Strength training and running

Running isn't just about racking up miles. To progress in the long term, reduce injury risk, and improve your running performance, incorporating specific strength training sessions is essential. This work, sometimes called GPP (general physical preparation), prepares the body to absorb repeated impacts and to generate more power with each stride.

Why strength training rhymes with efficiency?

Running primarily engages the posterior chains and core: hamstrings, quadriceps, calves, glutes, and deep abdominal muscles. By working these groups through strength training exercises, you stabilize your pelvis, control propulsion, and improve your running economy. In the long term, these muscular adaptations reduce fatigue and delay the onset of degraded technique, a classic source of injuries.

Structure of a typical session (20 to 30 minutes)

Rather than spending an hour in the gym, aim for three short strength training sessions per week, with 15 repetitions per exercise. Start with a dynamic warm-up (knee raises, butt kicks), then follow with targeted drills:

1. Single-leg squats (assisted pistol squat)
   
   

• Position yourself facing a bench or chair; descend with control until your opposite leg lightly touches the seat, then stand back up.
  

• Perform 8–10 reps on each side, ensuring your knee stays aligned with your foot.
  
  

2. Chest flyes shoulder-width apart on Swiss Ball
   
   

• Lie on your back, upper back supported on the ball, and perform flyes with straight arms; this specific exercise strengthens stabilizers and core.
  

• 12 to 15 repetitions, controlling the eccentric phase.
  
  

3. Walking lunges with leg change
   
   

• Alternating legs with each step, lunge forward. Ensure your knee bends to 90° and your core remains engaged.
  

• Do 10 lunges on each side for true unilateral work.
  
  

4. Straight-arm plank / plank position
   
   

• Hold the position on your hands and toes, with a neutral pelvis.
  

• Hold for 30 to 45 seconds, 3 sets, to strengthen your core and shoulders, pillars of your running posture.
  
  

5. Single-leg glute bridge
   
   

• Lie on your back, heel propped up, push your pelvis upwards while keeping one opposite leg raised.

• 12 repetitions per side to strengthen glutes and hamstrings.
  
  

Tips to maximize your gains

• Control the descent: eccentric training builds muscle fibers and improves shock resistance.
  

• Bodyweight first: master each movement before adding a weighted vest or resistance band.
  

• Progression: when 15 repetitions become too easy, increase the difficulty (bench height, slower tempo, transition to a more unstable Swiss Ball).

• Vary angles: alternate high/low seating, unstable/STABLE surfaces to constantly stimulate the nervous system.
  

Integrating into the training plan

Combine these short GPP sessions with your running outings: two running days, one strength training day, then a rest day or easy outing. In a typical week, you could do:

• Monday: jogging + strength training (30 min)
  

• Wednesday: interval training + GPP
  

• Friday: long run without strength training
  

• Saturday: strength training only
  
  

This type of pyramidal training (alternating endurance and strength) optimizes both muscle mass gain in key areas and the ability to maintain a good running pace.

In conclusion, combining running and strength training is not an option, but a necessity for anyone who wants to run fast, farther, and without injury. With these exercises and tips, you will lay a solid foundation for sustainable progress, whatever your target distance: 5 km or marathon.
