Lateral movements like this one are SO good for us. It challenges our bodies, because we are used to just moving front to back…not side to side. This strengthens your lower body and also stretches out your hips and inner thighs. Weight should be in the heel of the standing leg. Keep the alignment of the hip, knee and ankle of the standing leg…even as the other leg slides out, and you squat low. Core pulls in and your chest stays lifted. A lot going on here, but the benefits are worth it!
