Common Mistakes to Avoid
- !Rushing reps instead of controlling the lowering (eccentric) phase — aim for 2–3 seconds down.
- !Letting form break down as reps add up. Stop the set when technique slips, not when you physically can't do another rep.
- !Letting knees cave inward (valgus) — track them in line with your second toe throughout the rep.
Tips for Better Form
- ✓Breathe out during the effort (concentric) and breathe in on the return (eccentric).
- ✓Use a mirror or film yourself on your first session — your perceived form and actual form often differ.
- ✓Brace your core as if someone were about to punch you in the stomach. This stabilizes your spine in every rep.
- ✓Don't worry about load — master the movement pattern with light weight or easier variations first.
