Instructions for Proper Form
Similar to other curls, this isolation exercise targets the biceps. The use of a machine adds stability to the movement by forcing you to use a fixed range of motion. This added stability means you can focus more on exertion than stabilizing the movement. Since your range of motion is fixed, this is a great exercise for learning, or to push the limits of this movement.
- Sit upright in the bicep curl machine while resting the back of your arms on the arm pads.
- Extend your arms over the pad to grab ahold the handles with an underneath grip.
- With your arms parallel and in front of your shoulders, flex your elbows to raise the handles keeping your upper arms in contact with the pad.
- Once your forearms have come into contact with your biceps, Lower the handles back to the starting position.

Overusing Machines
Machines are great pieces of equipment, however they do hinder your ability to develop smaller stabilizing muscles. Try to work in other variations that require you to stabilize the movement as well.
Limit Range of Motion at the Bottom
There should always be tension on your biceps. It’s very common to lose tension at the bottom of the movement when your arms are fully extended. Limit your range of motion and keep your arm slightly bent to maintain tension in your biceps between reps.

Alternative Exercises to Machine Bicep Curl
1. Cable Bicep Curl

The use of cables allows you to apply tension to your biceps at a different angle than with free weights. This is especially helpful for applying tension at the top of your range of motion. Because you can maintain more tension on your biceps throughout the movement, this is especially helpful for building muscle mass in your biceps.
