Bicycle Crunch
Technique guide
Set-up
- Lie on your back with your hands lightly behind your head.
- Lift your shoulders and feet off the floor, knees bent.
How to do it
- Bring one knee towards your chest while rotating the opposite shoulder towards it.
- Straighten that leg as you switch to the other side.
- Continue alternating; each side counts as one rep.
Coaching cues
- Rotate through your upper back, not your neck.
- Move steadily, not as fast as possible.
Common mistakes
- Pulling on your head with your hands.
- Rushing the reps.
