Add some variety to your walks by trying the Grapevine (instructions below). If this tangles you up, do a sideways shuffle. Both moves work your inner and outer thighs, says Lalo Fuentes, a personal trainer in New York City. Incorporate a one-minute Grapevine every five minutes during your walk and alternate going to the right and then to the left.
How to Grapevine
1. Step your left leg across in front of your right leg.
2. Take your right foot to the right.
3. Step your left leg behind your right.
