Bicycle crunches get harder when the ball makes you balance.
Twist from your ribs, not your neck, and keep the ball steady underneath you.
The Stability Ball Bicycle Crunch isolates the Core — no passengers. That makes it a clean tool for adding targeted core volume without extra fatigue.
The Stability Ball Bicycle Crunch primarily works the Core.
Shorten the range or use an easier variation, and stop 1 to 2 reps before failure. Reps build fast when you train just shy of your limit.
For most lifters 3 to 4 working sets. Pick the rep range that fits your goal and progress the load when the top of the range feels owned.
