I think we can all agree that recovery from childbirth is pretty gnarly. As my husband likes to put it, its like our body is recovering from a bad car wreck.
Heel slide
Lie on your back with your knees bent and feet on the floor. Slowly glide one heel out until the leg is extended.
Bridge marching
Roll up into a bridge with your knees aligned over your ankles. In your bridge, lift one leg to table top, engaging the core, then replace the leg, keeping the hips up.
