What weight training workout should I do for running?
Your legs do a ton of work when you run, so building lean muscles in your legs is crucial for increasing your power and endurance. Moves like squats and lunges are efficient leg workouts for runners because they target most of the major (and minor) muscles in your lower body at the same time.
Dont forget upper body workout as you already put a ton of stress on the major muscle groups of the legs.
Running only moves you forward, which can lead to tightness and underdeveloped muscles in parts of your body. Strength and mobility exercises can help fix that.

Using only your body weight or resistance bands, runners can significantly increase their degree of mobility and stability, which can have a major effect on their movement patterns. Runners can see improvements from mobility and stability exercises, including:

  • Muscle Strength
  • Injury prevention
  • Increased range of motion
  • Balance
  • Power
  • Speed
