Exercise guide
Resistance Band Wrist Flexion
- Beginner
- Isolation
- Rep-based
- Lower arms
- Upper arms
This isolation exercise targets the wrist flexors on the underside of the forearm, essential for grip strength and forearm development. The resistance band provides progressive tension, meaning the resistance increases as you reach the peak contraction.

Muscles worked
Setup
- Sit on a flat bench with your feet firmly planted and secure one end of the resistance band under your foot.
- Grasp the other end of the band with an underhand (palms up) grip.
- Rest your forearm on your thigh or the edge of the bench so your wrist hangs just off the edge, palm facing upward.
How to do it
- Start with your wrist fully extended, allowing the band to pull your hand toward the floor.
- Exhale as you curl your wrist upward toward your body, squeezing your forearm muscles at the top.
- Inhale as you slowly lower your hand back to the starting position with a controlled 2-second tempo.
- Complete the set on one arm before switching to the other to maintain unilateral focus.
Form checklist
- Keep your forearm pinned to your thigh or the bench; do not let the elbow lift.
- Ensure the movement occurs only at the wrist joint.
- Maintain a full range of motion, from deep extension to full flexion.
- Avoid using body momentum or 'jerking' the band upward.
Pro tips
- At the bottom of the rep, allow the band to roll slightly into your fingertips to maximize the stretch on the flexors.
- Focus on a hard one-second squeeze at the top of the movement to maximize muscle fiber recruitment.
Make it harder
- Increase the resistance by 'choking up' on the band to shorten its length.
- Incorporate a 3-second isometric hold at the peak of the flexion on every rep.
