Written byMySetPlan Training Team

NASM-CPT, CSCS certified trainers. Every guide is built from peer-reviewed research and real coaching experience.

The Copenhagen plank is an advanced side plank variation that adds significant adductor (inner thigh) demand. By placing your top leg on a bench, you create a lever that loads the adductors isometrically. This makes it excellent for groin injury prevention and hip stability.

When to use it

Use for adductor strengthening.

Who it's for

Advanced lifters seeking to maximize strength gains.

Coaching Note

Set up in a side plank with your top foot on a bench and elbow under your shoulder. Lift your hips to create a straight line from top foot to head. Your bottom leg can touch the ground for assistance or hover for more challenge. Keep hips stacked, not rotated.

What are common Copenhagen Plank mistakes to avoid?

Hips sagging downward, indicating weak core engagement.

Losing hip position during the Copenhagen Plank shifts the loading pattern away from your Hip adductors and can compress your lower back. Stay planted and let your Hip adductors do the work.

Not stacking hips for optimal results.

Losing hip position during the Copenhagen Plank shifts the loading pattern away from your Hip adductors and can compress your lower back. Stay planted and let your Hip adductors do the work.

Holding breath, which reduces blood flow and can cause dizziness.

Holding your breath incorrectly during the Copenhagen Plank spikes your blood pressure and reduces core stability. Inhale during the eccentric (lowering) phase and exhale during the concentric (lifting) phase.

How to Program the Copenhagen Plank

Strength15-20 seconds per side

Lower reps with heavier weight builds raw strength. Your muscles and nervous system adapt to handle more load over time. This range is best for strength-focused goals.

Muscle Growth20-30 seconds per side

This rep range keeps your muscles under tension long enough to trigger growth. Most people see the best muscle-building results in this zone. It balances strength and muscle size.

Endurance30-45 seconds per side

Higher reps with lighter weight builds muscular endurance and improves conditioning. This range is good for joint health and building work capacity.

General guideline: 3 sets of 20-30 seconds per side. Rest 60s.
