The Chris Johnson Workout
Find out how the Tennessee Titans' running back stays at the top of his game
3 SINGLE-LEG SQUAT
SETS: 3 REPS: 8
"Everyone has a weak side of their body," Shaw says. "You can see, oftentimes with the single-leg squat, that a guy can do 180 pounds on his strong leg, but only 140 on the other. We want to make sure Chris is balanced." Johnson sets up in a Smith machine and takes a lunge position. He bends his front knee until his thigh is parallel to the floor. He works up to six reps on each leg.
