Bicycle Crunch (Bench)
A core exercise performed on a bench where the torso rotates and crunches while the legs perform a pedaling motion, targeting the rectus abdominis and obliques.
Instructions
- Lie on your back on a bench with your head and upper back supported by the bench.
- Place your hands gently behind your head with elbows out to the sides.
- Perform a crunching motion while simultaneously bringing one knee up toward the opposite elbow.
- Return to the starting position and repeat on the opposite side in a pedaling motion.
- Continue alternating sides for the prescribed number of repetitions.
Tips
- Keep your lower back pressed against the bench to maintain core engagement.
- Move slowly and deliberately to maximize core activation.
- This variation is accessible for beginners due to the bench support.
- The oblique component is important for balanced core development.
- Avoid pulling on your head and neck; let your core do the work.
