Ride more efficiently

Practice cycling one-legged to ride more efficiently.
This forces you to concentrate on pulling up at the bottom of the stroke, which better distributes the work among the major leg muscles.
Lock both feet on your pedals, but let your left leg go limp while you do all the work with your right leg. Do this for 30 seconds, then switch legs.
Ride normally for 5 minutes, then repeat the drill. Continue this way for a 20- to 30-minute workout.
