Squat against the wall
As a running you need endurance and also need to climb uphills and that is where the quad muscles come to play. Strengthening the quadriceps also help prevent injuries such as runner’s knee.
How to do it?
- Stand near a wall or some kind of support approximately 18 inches from the support
- Position your feet about shoulder width apart
- Lean back such that your back and head are flush against the support and you are in sitting position
- ensure you thighs are parallel to the ground and lower leg is perpendicular to the floor
