I’ve been working with some people who wanted simple exercises they could do that would stretch and tone simultaneously. This is one of the oldies but goodies from my dancing days, a plie squat with side reach.
It’s great for opening up your hips and stretching your adductor muscles and obliques, all in one.
Do this slowly as a stretch and do this quickly for a quick cardio blast. It is surprisingly tough on the legs as well so expect a bit of calf and quad soreness the next day!
