How to execute concentration curls.
To do a Concentration Curl, start by selecting the desired weight from the rack, and sitting in an upright position on a flat bench.
- Then, hinge forward and position your elbow against the inside of your thigh, making sure your upper arm is perpendicular to the ground.
- Slowly curl the weight up, only moving your forearms — the position of your upper arm on your thigh will help you keep it still during the movement.
- Concentrate on getting a full contraction at the top of the rep and squeezing your biceps.
- For strength, do three to four sets of six to eight reps per side, and for muscle, perform three to four sets of eight to twelve reps per side.
