How to do the machine preacher curls
- Sit down on the Preacher Curl Machine and select the weight.
- Place the back of your upper arms (your triceps) on the preacher pad provided and grab the handles using an underhand grip (palms facing up). Tip: Make sure that when you place the arms on the pad you keep the elbows in. This will be your starting position.
- Now lift the handles as you exhale and you contract the biceps. At the top of the position make sure that you hold the contraction for a second. Tip: Only the forearms should move. The upper arms should remain stationary and on the pad at all times.
- Lower the handles slowly back to the starting position as you inhale.
- Repeat for the recommended amount of repetitions.
Muscles worked
The prime mover is the biceps brachii, which bends the elbow and rotates the forearm palm-up.

How this movement works
One joint changes angle and the resistance travels toward you along a single arc. Nothing is positioned to help, so tension stays where you aimed it and the usable load drops sharply against a multi-joint pull for the same muscle. Protect the range of motion; buying weight by shortening the arc defeats the point.
It is filed under strength: produce force against resistance for a countable number of repetitions, and progress the resistance over time.
What you need
The machine fixes the path, removing the balance demand and letting you train close to failure without a spotter. The cost is the stabilising work a free weight would have made you do.

Difficulty
Listed at beginner level: the pattern is simple enough to pick up without coaching, and a position that goes wrong mid-set is obvious enough to correct on the next repetition.
