How to Perform the Alternating Knee Strike
- 1
Stand tall with feet shoulder-width apart.
- 2
Bring one knee up towards your chest, engaging your core.
- 3
Drive your knee forward and slightly upward as if striking a target.
- 4
Lower your leg and immediately repeat with the opposite knee, alternating sides.
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.
- ✓Keep ribs down and lats engaged — this keeps tension on the core, not the hip flexors.
- ✓Start each set with 1–2 warm-up reps at a lighter load to groove the movement.
