Hammer Curls with Cable Rope
Set a rope handle in the lower position of a cable.
Keep your elbows tucked close to your sides as you curl the weight up. Don't let them flare out. This helps isolate the biceps.
Focus on contracting the biceps as you lift. Concentrate on making a good mind-muscle connection.
Use a supinated or neutral grip (palms facing inwards or towards each other). This puts more focus on the brachialis muscle.
Keep your wrists straight and rigid. Don't let them bend back as you curl.
Use a full range of motion. Fully extend your arms at the bottom and curl all the way up but without moving elbows.
Go slow and controlled on both the positive and negative portion of the lift. Don't use momentum or swing the weights up unless needed or indicated.
Use a weight that fatigues your biceps in the rep range indicated for optimal hypertrophy. Increase the weight once the number of reps becomes easy.
You can do hammer curls seated, standing, or with bent knees for stability.
