@jamescharlesfitness: If you’re swinging the dumbbells, the weight is probably too heavy. Most people turn curls into a full-body movement. That takes tension away from the biceps. Set your shoulders back and down, keep your elbows close, and control the lowering phase instead of rushing through it. The goal isn’t just to get the weight up. It’s to keep the biceps loaded from start to finish. Less momentum. More tension. Better results. DM me COACHING if you want someone checking this stuff for you every week.
