Great Seated Core Exercise!

So, for beginners, you can use a chair with back support. It's going to be more challenging if you do not have back support like Brad is right now. And to begin, all you're going to do is work on just lifting one leg up. — I want to emphasize good posture, shoulders back, sit up tall. — Make sure your core muscles are engaged and you can keep in this posture. If you're real weak, you might end up leaning back into the chair if your tummy muscles aren't quite strong enough. But you're just going to lift one leg up, bring it back down, and then switch on the other side. Brad has to use a lot more balance and a lot more core stability without the back support. I'm not leaning back, so I am as well. If I lean back, this will make it a little easier. If you are weaker, — you could grab the armrest as well if you need some assistance. — So, this is how you can begin. Just do 10 reps on each side. Nice and slow. If you want to get a little more advanced, you can do both legs at the same time. So you can either sit like this, lift up, hold for 5 seconds, go back down.
