Numerous studies show the advantages of regular strength training for running economy. Muscles can use oxygen more efficiently. You can run faster and for longer. Strength training also prevents injuries. Even trained athletes make more use of one leg than the other while running. This can result in a muscular imbalance which compromises your performance. You are also more prone to injuries.
That is why it is useful to train each leg individually. Otherwise, the stronger leg will always support the weaker leg – and the imbalance increases because of the strengthening exercises.
1. One-legged squats to generate more power
Squats are among the most important basic exercises for runners. They are also used for rehabilitation after a sports injury. The squat works on the calf, thigh, and buttock muscles. Standing on one leg, slightly bend your knee to about 50 degrees. Then push yourself up to stand straight again. When doing this exercise, your hips must remain straight, and the knee you are bending has to be vertically above the supporting foot. Do the one-legged squat on alternate sides with ten repetitions and two sets. Slowly increase the number of repetitions later, and do three sets.
2. Heel lifts to generate more power and control
Stand on the edge of a step. The balls of your feet carry your entire body weight, with the heels overhanging the edge. Now stand on tiptoes. Lift one foot off the ground and return the heel of the other foot to the starting position. Carry out this exercise on alternate sides, initially with ten repetitions and two sets, then 15 repetitions and three sets.
3. Lunges to generate maximum power
The lunge is an intense strengthening exercise that uses every muscle during a leg work-out. Stand with your feet shoulder-width apart. Put your hands behind your head, and make one big step forward. Now lower your body as far as possible. Also, keep your back as straight as possible. The knee at the back almost touches the floor. From this position, push yourself back up to standing, and repeat the exercise with the other leg. Initially do ten repetitions and two sets, advanced athletes do 15 repetitions and three sets.
