Steps
- Lie flat on a bench while holding a dumbbell at arms length. Your arm should be perpendicular to your body. The palm of your hand should be facing towards your feet as a pronated grip is required to perform this exercise.
- Place your non lifting hand on your bicep for support.
- Slowly begin to lower the dumbbell down as you breathe in.
- Then, begin lifting the dumbbell upward as you contract the triceps. Remember to breathe out during the concentric (lifting part of the exercise).
- Repeat until you have performed your set repetitions.
- Switch arms and repeat the movement.
Tracking it in OneRep
Add the one arm pronated dumbbell triceps extension 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.
