There's so many different things you can do with a Bosu ball. Legs. Tons of different leg workouts. I'm going to give you an example of some you can do, beginner and advanced. One thing you could do is you could stand on it and just do regular squats. So you would just come down, come straight up, butt goes straight back, you come right back up, you squeeze your butt in, down, you come back up. A little bit more challenging, maybe you put your arms over your head and you do the same thing. Again, you want to make sure your back is flat though. You don't want to be arching and you don't want to let your knees pass your toes. So just down and up. A little bit more advanced version of that would be to flip it over and do the squats on the other side. So step on it and just, this in itself, if you've never been on a Bosu ball, is probably going to already work your legs out. Because you have little muscles in your legs that you very seldomly use. And once you get on this, you're going to start to feel them. You're going to be like, wow, I didn't know I had those muscles. Once you stabilize yourself though, then you can try doing a squat again. Same thing. You can add weights to that as well. So you would have the weights on, either side works on it. And then again you just squat down. You squeeze your butt up, you squat down, you squeeze your butt up. So, now other things that you can do on this is lunges as well. So you want to do the lunge on this side of the ball. So you can just step up, bring your knee up, come down, lunge behind you. Step up, come down, lunge behind you. Or you could do something a little more basic by putting one knee on and just going out for a nice lunge. By putting your arms out to the side, you can help balance yourself. You can drop it down. You can pick up weights and do it as well. So you go down. Even more challenging, you can just lunge, pick up a knee, go straight to a lunge, pick up a knee. You want to be careful. If you start to feel any pain in your knee, it may not be something you're ready for because you have to really use a lot of the stabilizing muscles, and a lot of your quads and hamstrings and if they're not strong enough yet, you might start to feel pressure on your knees. So you want to be careful with that. And then to get your cardio up, if you want to do cardio as well as legs at the same time, you can jump squat onto the ball. So, make sure nothing's around your Bosu. Jump up, squat down, you jump back, squat down. Jump up, squat down, you jump back, squat down.
