Adding weight while shortening the movement can make progress comparisons misleading. Use a suitable controlled, pain-free range and develop loading within it. Partial-range work has deliberate uses, but that does not make every shortened repetition an improvement. Body structure can also make appropriate movement look different between people.
Practical steps
- Standardise a controllable range
- Reduce load if technique changes
- Compare execution as well as numbers
A practical example
Squats performed through substantially different ranges are not a like-for-like strength comparison. Record deliberate technique changes.
How to review your decision
Check body position and equipment setup before adding load. Suitable range can vary with structure and experience, but movement should remain controllable without sharp pain. Distinguish ordinary muscular effort from joint pain and avoid unplanned swinging to finish repetitions. If setup is unclear, seek practical guidance from a qualified coach before testing a heavier load.
