The Starting Line
These two exercise are practiced by some of the best runners in the world. "They strengthen the key muscle groups needed for strong, fast, injury free running". Says Nick.
Lie down with your feet flat on the floor and place your hands underneath the small of your back, palms on the floor. Engage your abdominal and the press your lower back into the floor, crushing your fingers. Hold until you feel the BURN! Repeat 3-4 times to make it harder, lift one foot at a time a few inches off the floor.
The One-Leg Squat
Stand on one leg and squat as far as you can without your hips tilting or your knee turning in. This may be very shallow or further down, depending on your leg strength. Do two or three sets of 3-6 squats on each leg.
