If You Can't Do This, You're Not Fit (Even If You Look It)

This is Mariana. She's almost 60 years old, pulling herself up with just three fingers. And this is my aunt Melinda, who just turned 61, yet has never touched a weight. Today, I'm putting lifters and non-liffters, young and old, through seven sciencebacked fitness tests that you can try yourself, measuring strength, power, mobility, and conditioning. Every test is worth points, and we'll reveal the final scores at the end to find out how age and lifestyle actually impacts what your body can do. Because even if you look fit or you're strong in the gym, if you fail these tests, it'll reveal weaknesses that seriously affect how well your body holds up as you age.

Starting with power. You've probably seen this before. Bodybuilders look big and strong. But the second they try to sprint or jump, something looks off. I noticed this myself after years of soccer and sprinting growing up. I switched to bodybuilding style training and I lost my explosiveness. And the reason for this is muscle power. is what helps you move explosively, react quickly, and stay athletic. And if you don't train it, it's the first thing your body starts to lose, often as early as your 30s. And research has shown that it actually matters more than strength or size when it comes to how well your body and even your brain holds up as you age. So, how do you know if your power is actually holding up? So, the test we're doing is a bra jump, and that's going to measure your explosive power. If you can jump your own height, you pass the baseline test. And for those 55 and older, you pass if you can jump at least half your height. Whereas for the advanced test, you'll need to clear 2 m as a woman or 2. 5 m as a man. And if you can't even jump half your height, that is a clear warning sign that your power needs some work. We're taking the best of three attempts. Starting off with Robin. Even though he failed his first attempts, his next attempts were way better than I expected. Let's go, Robin. Wow, — that was very good. — Raven pushed past his second attempt, landing right at his own height to pass the baseline mark, which is impressive, especially considering he sits most of the day and doesn't exercise at all. But let's also not forget Robin at 29 is just reaching the age where he'll begin losing a lot of his natural muscle power. Yash is also 29, but he has been lifting weights for several years and actually plays volleyball recreationally. — Wow. — Yash easily passed the baseline test by clearing his own height. He didn't quite reach the advanced tier, but it was still a great jump. — Fix it. — Yeah, these are clean. — Both Yash and Robin earn one point for passing the baseline. And you can follow along, too. One point for baseline, two for advance. and I'll show you how you rank at the end. Next up is my aunt Melinda. She's 61 and has a very similar lifestyle to Robin. Because she's over 55, she only has to jump half her height to pass the baseline. — She barely made the cut, but she kept her spirits high and had a lot of fun with it. — Nice. Hey. — But Mariana is a complete opposite. always moving and lifting weights four to five times a week. She jumped nearly as far as the guys on her first two tries, but couldn't stick the landing. She finally found her footing on the last attempt. The jump had slightly less power, but she still walked away with an outstanding score for her age group. Now, compared to the younger guys, the main difference in Melinda and Mariana's muscle power has to do with their type 2 muscle fibers. These are the fast twitch fibers responsible for explosive movements. And when researchers examined muscle samples from people in their 20s all the way to their 80s, they found a huge drop in these type 2 muscle fibers. So for Mariana and Melinda, compared to the younger guys, they're already starting with fewer of these power producing fibers, which explains why my aunts just barely jumped half her height. Now, here's a detailed breakdown of how your jump ranks compared to young healthy adults. So to actually train it, all you really need to do is move weight quickly. Whether that's your own body weight through jumping and sprinting or in the gym with one of my personal favorite exercises, the kettle bell swing. Now, unlike a deadlift where you're controlling the weight slowly, these train your hips to produce force quickly. Make sure to use a lighter weight and add a few sets as a warm-up or finisher on your leg days. But for someone like Robin or my Melinda, you don't start here. First, you got to build a foundation, learning how to squat properly with something like a goblet squat. So, everyone earns one point for clearing the baseline, but nobody was able to hit the advance mark. By the end of the video, we'll total up all seven tests to see how well they're actually aging. So, while the broad jump

measured your explosive power, lower body strength and stability is just as important. And to test that, we are going to use the reverse lunge. The general benchmark is going to be 25% of your body weight in each hand with dumbbells. And you're going to aim for eight reps each leg. Melinda is out in less than a rep. However, Robin does last a tiny bit longer by using some questionable form. Unfortunately, that doesn't take him far, and he fails after four reps, leaving both him and Melinda with a zero for the baseline test. Now, as we wait to see how Mariana and Yash do, there's a few things I really like about this test. First, if you can't handle the required weight, it's a clear sign your lower body needs more strength or more stability to stay balanced. Second, both sides have to pass, which exposes strength imbalances between your legs, and that's way more common than you might think. Most people, they naturally favor one side. And with something like a squat, your stronger leg can quietly do more work and you'll still finish the rep. In my experience, for lifters, this can create all sorts of problems in your hips, your knees, and for me, it was my groin. And this only gets worse as you age. Research tends to show younger adults have a 5 to 15% difference between sides. But in older adults, that often grows to 15 to 20% or more. And when you trip or you lose balance, one side has to take over. And so if that side just isn't strong enough, that's when falls are much more likely. Now, both Mariana and Yash actually do this exercise regularly. So passing the baseline test for them was a piece of cake. Was that easy? — That was good. But the advanced test, it takes this to another level. Eight reps of the dreaded Bulgarian split squat, using 50% of body weight in each hand for men and 30% for women. For Yash, that meant holding 100 lb dumbbells in each hand. But there was just one problem. — You don't have 100 lb. — I don't have hundreds. To make up for the lighter weight, we bumped Yash's target up to 10 reps. — One. Two. Come on. Three. Four. You're halfway there. You got it. Five. Three more. Six. Seven. Last one. Go all the way down there. Good. Nine. Come on. Last one. Oh, no. — It doesn't want you stability. No. Okay. — All right. You got it. — So close. We — were so close. — Oh my gosh. — I'm not going to lie, that advanced test is no joke. So, if you try it, let me know how it goes on the comments. But if you had trouble with just a basic test, then start with a stationary split squat to build strength and control. then progress to the reverse lunge until you can handle 25% of your body weight in each hand before moving on to the final boss, Bulgarian split squats. And for most lifters, keeping at least two to three single leg exercises in your routine is one of the simplest ways to prevent imbalances as you get stronger. But with test two finished, here's what the scores are currently at. We still got five more tests to go, and the last one might look like a piece of cake, but it's actually the one that most people struggle with. The next question is simple. Can your upper body actually pull its own weight? This test measures the strength of your lats, your upper back, and your biceps. And if you can't even pass the baseline, it's a sign that your upper body strength and muscle mass aren't keeping up with your body weight.

Okay, so for this test, we're going to use an underhand grip. You're going to start from a dead hang and then you're going to pull until your chin crosses the bar. So, one body weight chin up is the standard general benchmark. And then if you can pass that, we have some advanced benchmarks where we're going to add weight. Hang. All right. Pull. Go. — Oh, nice try. Next up is Yash. The baseline test was a piece of cake for him, locking in this point while Robin takes zero. So, we're moving him on to the advanced test. Three or more reps with an additional 40% of your body weight. And for women, we're bringing the requirement down to just five or more clean body weight reps. The gym bros will be looking up to light weight. One up. Yeah, that's good. Come on. One more. Drive the elbows down. No. So close. As for the senior group ready, — are you hanging? This is like when I was a kid. This is the opposite now. Monkey bars. All right. Pull. — Hold on. I can — pull. Now, unlike the power test, Melinda wasn't able to get a single rep. And that's because going from zero to one rep, no matter your age, is a massive jump. Later, I'm going to show you how to bridge that gap. But first, let's clean. Nice. Three. Easy. Wow. Dennis, you got to get a shot of these back muscles. Holy crap. — Holy. — Oh, wow. — Easy. — Was that five? I'm just in awe. — Ariana easily placed herself in the advanced category. But that's not the end. She's about to show us something I had never seen before. That's crazy. I don't even know if I can hang with three fingers. — Yeah, that's pretty wild. Oh my god. — Honestly, this is way harder than it looks. And I was genuinely shocked how strong Mariana actually is. How did you get so strong with pulling? You're a climber, right? — Yeah. — Oh, yeah. — I saw you earlier. I was like, damn. Like her forearms. — Yeah. More muscular than my forearms. I feel holy crap. When you go to the gym, how often are you practicing chin-ups, pull-ups? — I try to do a minimum of five. So I stress my body because when I go climbing I need to make sure I climb I'm not at fault. So I rely on every body part. — Now climbing is just one of the secrets behind how Mariana manages to stay in such incredible shape. But she's not just strong, she's also insanely lean as well. In fact, based on her DEXA scan, she clocked in at under 17% body fat. That's top 1% of the population lean and the equivalent of sub 10% body fat on a man. And later, I'm going to show you exactly how she does it. But if you can't bang out chin-ups like Mariana, you'll want to start with the inverted row to build your back strength. And then move on to band assisted chin-ups, which even someone like Robin with zero exercise could already do. And then over time, you use smaller bands until you can do unassisted chin-ups, which is when you want to start adding more weight. every time you can do eight reps pretty easily. So, for our next four tests, we're actually moving away from

strength. And I know a lot of you are definitely neglecting this next one, which is testing your cardiovascular fitness. Now, when people say being out of shape is worse than smoking, they're not just being dramatic. A massive study on more than 120,000 patients who performed treadmill testing found that low fitness carried a risk comparable to things like diabetes, high blood pressure, and yes, even smoking. In fact, many researchers are now suggesting that being fit is far more important for your health than what you eat. Today, we're going to do a onem run. Melinda, do you do any form of cardio? — Never. — I just only walk every single day. — I bike. I do cardio. Yes. I used to be like run the sunun back in high school. — Okay. — I was in like a running club. — I love walking tide running sometimes, but no, I'm not good at running. — 3 2 1 go. And right out the gate, Yash and Robin are taking off in the lead while Mariana is sticking to a manageable pace while I'm personally helping my ass set her pace for lap one. The first lap, it'll like raise your breathing. — Oh yeah, — it'll feel harder, but then your body will get used to it. Now, typically researchers test your cardio fitness with a V2 max test. You run as hard and as long as possible until you give up, and afterwards you get a score that represents your fitness level. But the good news is a simple onem run test is a pretty good way to gauge your cardio fitness on your own. For the baseline score, you should be able to run a mile in under 10 minutes if you're younger or under 12 minutes if you're over 55. For me personally, I'm currently under 6 minutes, placing me at an advanced level, which is under 7 minutes. Whereas, if you're over 55, 9 minutes or less is the advanced benchmark. And you can also easily do these tests on the treadmill. Just set the treadmill to these speeds in miles per hour for the designated time. But just half a mile in, Robin burned out from his early sprint of the gate. Well, to my surprise, Yash is actually on target to beat the advance time if he can hold this pace. Now, even though Yash doesn't do any formal cardio anymore, he has built a solid base from his early years of running and playing sports, which he seems to have been able to maintain just from doing big lifts in the gym that get his heart rate up. But he's also got his age on his side. Because after your mid20s is when your cardio fitness starts to silently decline by about 1% per year. It doesn't sound like much, but this can eventually reach a point where climbing a set of stairs or keeping up with your friends on the hike becomes very difficult. I'm noticing this firsthand with my aunt. This is good. — No breath now. — While she is trying her best, I can hear the wheezing in her breathing, and she was nowhere near Mariana's pace, who seemed to also be on track to beating the advance time. When it came to the finish line, Yash actually crossed first, but he missed the advance time by a few seconds. 7:16. Wow. Mariana followed behind him, officially clocking in at 9 minutes, beating the advance time for her age. And after a few minutes, Robin, who burned out early, finally crossed the line. — Wow. 12. — 12 minutes. — And as for my aunt, almost there. You got it. — Close. — Let's go. Almost there. — Close. — Almost there. — Yes. Wow. — Thanks. Thanks, — Ramon. Are you okay? — I would rather have less life expectancy than running. Mariana was the only one able to beat the advanced time, putting her in the top tier of cardio fitness for her age. But perhaps an even bigger benefit of cardio is what it does to your belly fat. Specifically, the dangerous visceral belly fat deep in your organs that's linked to disease and death. Now, if you don't exercise much and you eat a lot of sugar and fatty foods and you notice that your belly is full and firm to the touch, you probably have a high amount of this fat. In fact, both Melinda and Robin had alarmingly high levels based on their Dexter reports. But the good news is cardio is the most effective form of exercise to burn off this visceral fat even without losing weight. Which is why we added cardio exercises to our Built with Science Plus app. And this is actually where Mariana stands out. She not only has extremely low body fat, but her visceral fat is virtually non-existent. And from just one day together, it's clear to me why that is. Rather than driving, she actually biked over to meet us for the onem run test. And she regularly goes for hikes and just finds ways to stay active no matter what time of year it is. She is the only one who came prepared with a full day's worth of food. Greek yogurt oats for breakfast, a smoked salmon bagel for lunch, plenty of healthy protein and complex carbs to fuel her activity. And this is actually what researchers call a high energy flux lifestyle. She eats more, but she also moves more. And that combination has been shown to be one of the best long-term strategies to lose fat and keep it off for good. The good news is when it comes to cardio, just walking more is a great place to start, but it needs to be challenging. So try alternating between faster and easier walking for about 30 minutes. And then over time, you'll want to include more demanding cardio that actually gets your heart rate up a few times a week. Running, cycling, swimming, or sports. It doesn't matter what you choose as long as it feels challenging and is something you can actually stick to. And if you want more ideas, I'll link a video in the description box down below where we scientifically measured the calorie and fat burn of almost every cardio exercise you can think of. So, this next test is going to test your

upper body mobility. Over 90% of people actually fail this simple test. Usually, it's because of poor posture, sitting all day on the computer, or they're lifting weights in the gym, but a lot of what they're doing is just imbalance. All you need is a wall. Stand roughly a foot back from the wall and rest your glutes and upper back against it. Then bring your arms up into a goalpost position with your arms at 90° while making sure the back of your head is still touching the wall. Now, if you can't get your arms to 90° with the back of your hands touching the wall or you can only get there by sticking your head forward or arching your lower back, that's a fail. And then advanced is can you slide all the way up while keeping everything intact? This seems easy. — It looks easy, but that does not feel easy. Okay, — Robin. Robin, Mr. Looks easy. Let's go. — Touching the wall. Slide up. All the way up. — It's back. It's back. It's back. — I don't know. My back is — No, it's just your It's because you don't have the mobility that you're going like this, right? No, it's because I sit all less, so my back is covered. — I know, but that's for that's the point of this test. — All right, get out of here. — Can you lift your hands up at all? — I mean, my elbow is coming. — Come on. — This is not something you can force your way through. — Yeah, right. — It's okay. — Nice try. Now, — you'll often see strong lifters who do a lot of pressing really struggle with this test. Their bigger muscles tend to overpower key muscles like the mid and lower traps that help open you up and control proper shoulder movement. It's probably why when I tested three other guys at the gym, they all failed. Whereas both Mariana and Melinda passed with flying colors. Keep this flat and go down. — Yes, I did it. — You did it. — If you struggle with this, the fix is actually really straightforward. You want to start with a band or towel and do over and backs for three sets of 10 to 20 reps to open up your shoulders and chest and then follow it with a set of wall slides to actually strengthen some of these back muscles. For me, I do this like 10 times every morning. — Oh, really? — Yeah. Every single morning. This really helped with a lot of my like shoulder issues, — tightness in my upper traps and my neck. All went away once I started doing this.

Okay, so we just have two tests left. And this next one, if this muscle is weak, it's going to negatively affect everything that you do. Most people train their abs for how they look, but that's not what they're most important for. Your core, which includes your six-pack, are all the muscles around your waist. And they're what keep you stable and strong. Whether you're catching yourself from a fall or doing heavy squats and deadlifts. But when your core gets weak, your lifts in the gym not only start suffering, but your posture and your balance can break down. And you can even become more prone to back injury, the leading cause of disability worldwide, which can affect you at any age, whether your goal is to lift pain-free, play with your kids in your 40s, or just stay active and mobile through your 70s and 80s. And to test it, the baseline test is 25 controlled roll downs and 50 for advanced. You're going to start up here and your hands are in front of you. You're going to come down very slowly. Flatten your back. Then reverse by slowly flexing your spine in a C-shape. No momentum and no leading with your neck and go. Just go slow. There you go. Good job, guys. Melinda is out. Now, you can train your abs all you want, but they're not going to show unless you do this. To make them pop, you want to get down to at least 15% for men and around 25% for women. And that's mainly driven by your diet. Let's go, Robin. Come on. You got it. That's exactly why we created the Built with Science app. It takes care of both your training and nutrition for you and has helped members of all start importance and ages lose fat, build muscle, and get into the best shape of their lives. You can try two weeks for free over at builwithcience. com or by scanning this QR code. And oh my god, I cannot believe Mariana is still going. That is insane. Let's go. 48 49 — 50. — Wow. She could go all day. — Crazy. That is insane core strength. And with Mariana easily hitting the advanced score, I had to know how she was training. So, there are a couple things I do. Then I go on to that sweep. — That's my toes. — And while I'm definitely going to try Mariana's core training myself, if you're already lifting weights, especially with free weight compound exercises, you're probably training your core more than you think. But you can always benefit from training that directly, especially if you struggle with this test. For beginners, use the rolldowns as both your test and your training tool, starting with partial reps and then gradually build up to full controlled ones over time. Whereas, as you get more advanced, some of my personal go-tos are RKC planks, ab rollouts, and weighted crunches. And if you do want to mix it up and take it to another level, this is what Mariana does every week. I also added some of her ab exercises into our Build Science Plus app so you too can become Mariana. Okay, so for the next test, if you do this

test poorly, your risk of dying actually increases by up to five to six times. All you have to do is sit down and stand up. Back in 2012, a group of researchers had 2,000 adults between the ages of 51 to 80 do this exact test. Now, you get five points for sitting down and five for standing up, but you lose points each time you use support, like with your hands or your knees. Now after the test, the researchers followed these individuals for over 6 years to see how well this test predicted survival. And during that time, 159 of them passed away. And what they found was striking. Those who scored poorly were five to six times more likely to die than those who scored well. So out of all the tests today, this is the one I'm most interested in, especially for our older participants. And for our baseline test, we're keeping it simple. No support, you pass. Any support you fail. — Okay. — Oh, nice. Nice. — Do it together. — Together. — So, no hands, no support. Okay. — Oh, jeez. Okay. — Whenever you're ready. — You did it. What happened? — No, — I don't think I can do it. — This is where things get interesting. Yash is way stronger than Robin, but still couldn't pass this test. Because this isn't just about your lower body strength. You also need enough mobility in your hips and your legs. And even though Robin doesn't lift at all, the one thing he does do is a 10-minute yoga routine every morning, explaining why you actually outperform Yash in both our mobility tests. — You can do it. No, — you got it. You got it. — Oh, — okay. One hand. Good job. — You got to work on your leg strength. — Yeah. — Wow. — Easy, easy. — Now, the advance. I don't think I could do the advance. — Uh-oh. — Does that count? We need a demo from — the other day. WHOA. — WOW. — DENNIS. — Dennis mentioned it might be due to his background. Growing up in Taiwan, they sat on the floor a lot during school assemblies. So, he's essentially been practicing this movement ever since he was a kid. And even now at home, he still sits on the floor more than on the coach, which explains why his mobility is naturally better than everyone else here. And if you want Dennis's level of mobility, start with a 9090 stretch to open up your hips. Hold each side and use your arms for support. Then gradually work towards doing it without your hands and windshield wiping your legs. And then finally progressing into a getup. I personally do just five reps of these every single morning, which has been just enough for me to keep my hips moving well. Here's everything we

tested, and here is every exercise we covered to improve each test. Focus on your weakest areas. And honestly, guys, just don't overthink it. Out of all the tests we did, you could have scored a total of 14 points. Melinda, you got three points. Robin, you scored three points. Yash, you scored five points. Mariana, 12 out of 14 points. — Wow. — Yes. — Vote for me. I'll be the next prime minister. — We found the different areas that you guys need to work on. I think like Robin and Melinda, it's very clear that you just need to start something. I would highly recommend one of those things be strength training. It's never too late to start. When you're 70, when you're 80, when you're 90, I want you to still be healthy and still be around. And the same way that you took care of me, I want to start taking care of you. — A Okay. — What a good guy. — Do you have any advice for people watching who want to stay in shape as they're getting older? — So, start as soon as you can. And anything just find anything you like. Those days that you don't feel good, just do something. Stretching, yoga, something. Just push a little bit. Push yourself a little bit. That's it. If I inspired anybody, I'm super happy about that. — Give this video a watch next and give a like and shows your support for all these amazing people for joining us today. All right. Yes.
