Pro tips
- Move through the full range of motion under control.
- Keep tension on the target muscle — avoid using momentum.
- Breathe out on the effort, in on the return.
- Pick a weight that lets you keep clean form for every rep.
Common mistakes
- Using too much weight and sacrificing technique.
- Rushing reps instead of controlling the tempo.
- Cutting the range of motion short.
- Holding your breath throughout the set.
Safety notes

- Stop immediately if you feel sharp or joint pain.
