Bicycle Crunch
A tougher crunch variation where your torso stays lifted and your core stays engaged the whole time. Pedaling your legs adds instability and the twist brings in the obliques, so it hits the core harder than a standard crunch.
How to do it
- 1
Lie on your back with hands behind your head and hips and knees bent to 90 degrees.
- 2
Extend one leg away while keeping both feet off the floor.
- 3
Draw that knee back in toward your chest, keeping your shins roughly parallel to the floor.
- 4
As the knee comes up, rotate your upper back to bring the opposite elbow toward it, without yanking on your head.
- 5
Return that leg to 90 degrees and lower your shoulders, then repeat to the other side, alternating.
