Gym Move 1: One-Legged Lunge
Works: thighs, butt (Bonus: core)
A. Stand about one leg’s distance in front of the ball, facing away from it. (Hold on to a wall or sturdy object for balance, if needed.)
B. Tighten abs and place left foot and ankle, shoe’s sole up, on ball. Left leg should be bent. Bend right leg, aligning knee over ankle, and lower hips toward the floor. The ball will roll slightly back and away.
C. Hold two seconds, straighten right leg. Do eight to 12. Switch sides.
Tip: Select the right-sized ball: When sitting, your legs should bend to about 90 degrees.
