Modified bicycle crunches (low-strain core work)
A modified bicycle crunch trains the abs and obliques like a normal bicycle crunch, but with less neck and lower-back strain. It’s ideal for beginners, rehab, or anyone with back sensitivity.
🔹 How to do it (correct form)
1. Start position
o Lie on your back
o Knees bent, feet off floor (tabletop)
o Hands lightly behind head or arms on floor
2. Brace first
o Tighten core
o Flatten lower back to floor
3. Small movement
o Bring one knee toward chest
o Rotate torso slightly toward that knee
o Other foot stays higher (not fully extended)
4. Switch sides slowly
o Controlled pace
o Keep lower back down
________________________________________
🔹 Key cues (don’t skip these)
• Move slow, not fast
• Elbow moves toward knee via torso rotation (not pulling neck)
• Lower back stays on floor
• Range of motion = small but controlled
If your back arches, you’ve gone too far.

🔹 Programming
• 2–3 sets
• 8–12 reps per side
• Slow tempo (2–3 sec per rep)

🔹 Why it works
• Targets abs + obliques
• Lower spinal stress than full bicycles
• Good for core rehab progressions
• Builds control before harder exercises
