よくある間違い
Excessive Torso Sway (Cheating)
Using momentum from the lower back and hips to lift the weight reduces the work done by the biceps. This not only diminishes muscle growth but also places undue stress on the lumbar spine, increasing the risk of lower back injury, especially with heavy loads.
Incomplete Range of Motion
Failing to fully extend the arms at the bottom or fully contract the biceps at the top limits the muscle's time under tension and the overall stimulus for growth. Partial reps can lead to underdeveloped muscle fibers and reduced strength gains across the full range.
Flaring Elbows
Allowing the elbows to move forward or flare out significantly during the curl shifts tension away from the biceps and onto the anterior deltoids and forearms. This reduces the effectiveness of the exercise for bicep development and can place stress on the shoulder joint.
