Steps

  1. Sit down on the Preacher Curl Machine and select the weight.
  2. 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.
  3. 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.
  4. Lower the handles slowly back to the starting position as you inhale.
  5. Repeat for the recommended amount of repetitions.

Tracking it in OneRep

Add the machine preacher curls to a routine and your previous weight and reps sit beside every set, so the decision to add load is made by what is already on the screen rather than by memory. Exercise history and volume trends are one tap away, and logging works offline for the gyms where signal does not reach.

Because OneRep tracks food on the same timeline, a stall on this lift can be read against what you were actually eating that month — which is the difference between a programming problem and an eating one. More on that in tracking progressive overload without a spreadsheet.

Where the instructions come from

The steps above come from free-exercise-db, a public-domain exercise dataset. They are general guidance, not coaching for your body: if a movement hurts, stop and get someone qualified to look at it.
