Copenhagen Adduction Exercise (CAE)
A high-value adductor strength exercise using a side-plank setup that challenges inner-thigh strength and hip/pelvic control.
EPI video demonstration · Watch on YouTube
Muscles Targeted
Primarily the adductors (longus, brevis, magnus, gracilis, pectineus). You’ll also feel obliques, glute medius, and trunk stabilizers working to hold the side-plank position.
Key Benefits
- High-demand adductor strength option with strong transfer to sport and running
- Trains inner-thigh strength with trunk and hip control at the same time
- Easy to regress or progress by changing leverage and support
- Excellent exercise for groin-strength progressions
Equipment Needed
A bench, box, chair, or partner support surface (as shown in the video) to support the top leg.
How to Perform the Copenhagen Adduction Exercise
- Set up in a side-plank position with the top leg supported on a bench/box as shown.
- Stack shoulders, hips, and ankles and keep the pelvis steady.
- Drive the supported leg down into the bench/box while lifting the body.
- Keep breathing and maintain a clean, controlled position.
- Use the regression/progression options in the video to match your level.
Programming Options
- 2–4 sets of 10–25 seconds holds each side
- or 2–4 sets of 4–8 controlled reps each side
- Start with a regression and build leverage over time
Why This Variation Works
The CAE challenges the adductors with significant load while the trunk and hips stabilize the pelvis. That combination makes it a strong option for building resilient inner-thigh strength.
When to Use It
Use this in dedicated groin-strength progressions, as accessory work on lower-body days, or as part of return-to-sport strength programming.

Frequently Asked Questions
Is the Copenhagen exercise supposed to feel hard?
Yes—this is a high-demand exercise. Use the regressions shown in the video and build gradually.
Where should I feel it?
Primarily in the inner thigh of the top leg, plus the trunk/hip stabilizers working to hold position.
How do I know if I should regress?
If you lose pelvic control, can’t hold alignment, or symptoms spike, choose a shorter leverage/regression and rebuild.
