Triceps Extension Machine
Muscles worked: Triceps.
How to do it
- Adjust the seat to the appropriate height and make your weight selection.
- Perform the movement by extending the elbow, pulling your lower arm away from your upper arm.
- Pause at the completion of the movement, and then slowly return the weight to the starting position.
- Avoid returning the weight all the way to the stops until the set is complete to keep tension on the muscles being worked.
Coaching cues
The two cues IronPack shows on this exercise's card mid-workout:

Logging it
IronPack suggests working in the 10 to 15 rep range, progressing in 2.5 kg jumps when you own the top of the range. Records are tracked automatically at every rep count from 1 to 12. Check your estimated 1RM from any hard set.
