Steps
- Grab a dumbbell with each arm and place the upper arms on top of the preacher bench or the incline bench. The dumbbell should be held at shoulder length. This will be your starting position.
- As you breathe in, slowly lower the dumbbells until your upper arm is extended and the biceps is fully stretched.
- As you exhale, use the biceps to curl the weights up until your biceps is fully contracted and the dumbbells are at shoulder height.
- Squeeze the biceps hard for a second at the contracted position and repeat for the recommended amount of repetitions.
Tracking it in OneRep
Add the two-arm dumbbell preacher curl 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.
