The Newest Speed Secret
A slight change to a popular exercise might cut your 40-yard-dash time, say researchers in Sweden who found that jumping lunges can help sprinters gain speed. Jumping adds explosiveness to the exercise, the researchers say, activating muscle properties in a manner similar to sprinting. Try it for yourself: Lower your body into a lunge, jump up, switch legs in midair, and land with the opposite leg forward. Drop down into a lunge again and repeat. Twice a week, do 4 sets of 12 reps with 60 seconds of rest—the exact routine used in the study.
