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.
Lie on your back with your knees bent and feet on the floor. Slowly glide one heel out until the leg is extended.
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.
