Another combo killer workout you can do on the BOSU, which is really intense and incorporates your whole body, upper, lower, core and cardio is a squat jump on, and then either a push-up or tricep push-up while off. So it would look like this, a squat jump on. You jump back into a squat, hands come down, and you either do a regular push-up or you can do a tricep push-up, which is a little bit more strenuous and also gets the triceps, as opposed to the chest. Then you jump back in and do it again, so a faster version would look like this. Again, that type of combination would be really good for your entire body, because you get everything included in one.
