To improve your running you need to improve your muscle endurance and this means that you need the core strength: one minute crunch. Set your stop watch and grit your teeth – one minute of pain equals a future of running GAIN.

- Look up to the ceiling.
- Crunch up by lifting your head and shoulders off the floor.
- Repeat the move for one minute.
Push your lower back into the ground to keep your spine stable.
