How to Perform the Assisted Copenhagen Plank
- 1
Lie on your side, propped up on your bottom forearm (elbow under shoulder).
- 2
Place your top leg (straight) on an elevated surface (bench).
- 3
Bend your bottom leg and place the knee on the ground for support.
- 4
Lift your hips off the ground, forming a straight line from head to top foot.
- 5
Engage your core and the adductor (inner thigh) of the top leg.
- 6
Hold this position for the desired duration.
- 7
Switch sides and repeat.
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.
- !Using momentum instead of muscle tension. Slow the tempo and feel the target muscle doing the work.
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.
- ✓Start each set with 1–2 warm-up reps at a lighter load to groove the movement.
