Handle Band Crunch
The Handle Band Crunch is a resistance-based core exercise that targets the rectus abdominis through controlled spinal flexion. By using a resistance band anchored high, this movement provides continuous tension on the abdominals, offering a functional alternative to traditional floor crunches for developing core strength.
Since band tension varies based on stretch length, Iridium relies on your RPE inputs rather than 1RM estimates to track progressive overload for this movement. The system counts this work specifically toward your Upper Abs weekly volume landmarks, aiming to hit your Minimum Effective Volume without exceeding your recovery capacity for the core.
Form Cues
- Anchor the band high and kneel facing away from it
- Hold the handles by your ears or neck stationary
- Exhale deeply as you curl your chest down toward your pelvis
- Round your spine to fully contract the abdominals
- Control the resistance slowly on the way back up
- Don't pull the handles down with your arms
- Don't sit your hips back onto your heels during the rep
- Don't keep your back flat or straight
- Don't allow the band to snap you back to the start
Common Mistakes
- Using arms to pull instead of abs
- Hinging at hips instead of curling spine
- Rushing the eccentric (upward) phase
- Sitting back on heels
- Arching the lower back at the top
Muscles Worked
This exercise primarily targets the upper rectus abdominis (the 'six-pack' muscles) by forcing the spine to flex against resistance. Unlike floor crunches, the band provides varying resistance that peaks at the point of strongest contraction, while also engaging the transverse abdominis and obliques to stabilize the torso.
