Bicycle Crunch
A step-by-step form guide from the Ægir Iron exercise library: how to do the lift, what to watch for, and the muscles it trains.
- Equipment
- Bodyweight
HOW TO PERFORM
- Lie on your back, hands lightly by the ears, shoulders curled off the floor and the legs raised with the knees bent.
- Bring one knee in and rotate the opposite shoulder toward it while the other leg extends out straight.
- Switch sides in a steady pedalling rhythm, keeping the low back flat.
FORM TIPS
- Rotate the ribcage toward the knee, not the elbow. Pulling on the head only moves the neck.
