Cat/cow

This yoga exercise gives “a nice stretch to the lower back and works through the core and hips,” Stover says. Start on your hands and needs, with your head in a neutral position. As you inhale, lift your tailbone and chest toward the ceiling, allowing your belly to sink. Lift your head and look straight ahead (don’t crank your neck.) As you exhale, round your spine as you release your head toward the floor.

Squat/shoulder press combo

Hold dumbbells by the shoulders or the hips. Squat, then lift dumbbells and lower them.  This exercise works through the hips and butt and builds upper-body strength—great for holding your baby.

Alternating leg extensions

Begin on all fours. Extend one leg straight back, then bring it back in place. Switch sides. This exercise works the upper body as you stabilize you’re your hands, Stover says. It also builds strength in your gluts and back, engaging your core but without too much of a load.
