Strengthening your lower body is one of the best ways to build speed, says former world champion marathoner and physical therapist Mark Plaatjes. Do these five exercises two or three times a week during base training.
Single-leg Squat
Squat down on one foot until your leg is bent about 50 degrees; push back up. "Keep your hips even, and your knee over your foot," says coach Bob Larsen. Once you've mastered the move, add dumbbells (start with 5 pounds).
Reps: 2 sets of 10; build to 3 sets of 12
Strengthens: Quads and glutes
Balance Run
Stand on a flat-bottomed stability trainer (or a narrow board). Hold light dumbbells (2 to 5 pounds) and swing your arms in a running motion. Keep your knees slightly bent and your abs tight.
Reps: 3 sets of 30 seconds
Strengthens: Core muscles and hones balance
Heel Raises
Stand on a curb or platform with your heels over the edge. Lift up onto your toes, raise one foot and slowly lower. Once you have the move down, add dumbbells (start with 5 pounds).
Reps: 1 set of 8; build to 3 sets of 15
Strengthens: Calf muscles and Achilles tendon
Hamstring Push-up
Lie on the floor with your feet
on a chair or Swiss ball that's against a wall. Lift your butt off the floor, then lift one leg off the ball. Slowly lower your body to the floor, using the hamstring of the supporting leg.
Reps: One set of 8 on each leg; work up to 3 sets of 12
Strengthens: Hamstrings
Plank + Lift
From a push-up position, drop onto your forearms. Focus on pulling your abdominals in. Then lift one foot about six inches (keep hips square to the floor), hold for five seconds, and repeat on other side.
Reps: Continue for 60 seconds, build to 3 minutes
Strengthens: Core and glutes individually
