Film from the side
Your feel is unreliable under load. A side on video of a working set exposes depth, bar path, and spine position far better than a mirror or how it felt.
How do I know if my form is good?
Good form means smooth controlled reps, the target muscle working, stable joints, and no sharp pain through a full range.
The quick answer
Judge form by control and consistency, not just how much you lift. Reps should look the same from first to last, move through a full range you own, and drive tension into the target muscle rather than random momentum. The clearest test is filming from the side and comparing against a coaching cue for that lift. Sharp joint pain is always a red flag.
How to think about it
Control beats ego
Good reps are smooth with a controlled 2 to 3 second lowering, no bouncing or jerking, and the last rep resembles the first. If it turns into a whole body heave, the weight is too heavy.
Right muscle, no pain
You should feel the intended muscle working, not sharp pain in a joint. Aches in the target muscle are fine, but stabbing or pinching joint pain means stop and reassess.
Do this
- Record a setFilm from the side at working weight and compare against a known technique cue.
- Test with lighter loadIf form breaks down, drop the weight until every rep looks identical.
- Check the rangeMove through a full range you can control rather than partial ego reps.
- Watch the last repsIf the final reps get sloppy, stop the set there rather than grinding.
When to see a professional
If a movement causes sharp, persistent, or worsening joint pain, stop and see a physio before loading it again.
