Lying Supine Dumbbell Curl

Lie back like a cozy bear in a den, then curl those dumbbells like you are scooping up two jars of honey. Keep your elbows tucked and your paws steady so the biceps do the work. Slow curls, big squeeze, no wiggly salmon-flop cheating.

Instructions

1. Lie on your back on a flat bench (or the floor) holding a dumbbell in each hand, arms straight and palms facing up.
2. Set your shoulders down and back; keep your upper arms close to your sides.
3. Curl the dumbbells by bending only at the elbows until the weights are near your shoulders.
4. Squeeze your biceps briefly at the top without letting elbows drift forward.
5. Lower the dumbbells slowly to full elbow extension, keeping tension in the biceps.
6. Repeat for the desired reps.

Benefits

• Isolates the biceps with reduced body swing
• Improves mind-muscle connection for elbow flexion
• Builds biceps strength and size with minimal equipment
• Can be easier on the lower back than standing curls

Key Points

• Keep elbows pinned; only the forearms should move.
• Use a slow, controlled lowering phase.
• Maintain neutral wrists; do not let them bend back.
• Keep shoulders packed to limit front-delt takeover.
• Stop 1 to 2 reps before form breaks down.

Common Mistakes

• Letting elbows drift forward, turning it into a front-delt movement
• Swinging the dumbbells or using momentum
• Bending the wrists back instead of keeping them neutral
• Cutting the range of motion short
• Lowering too fast and losing tension
