The Copenhagen adduction exercise, more commonly known as the "Copenhagen plank," is a highly effective and versatile exercise that hits the core and the adductor muscles of the inner thighs.
This exercise, which originated in Denmark (hence the name), has gained popularity among athletes, fitness enthusiasts, and rehabilitation specialists due to its ability to enhance stability, strength, and overall athletic performance.
In this comprehensive guide, we will explore the mechanics of the Copenhagen plank, its benefits, variations, and how to incorporate it into your workout routine.

Understanding the Copenhagen Plank
The Copenhagen plank is a dynamic exercise that combines elements of a side plank with adductor activation. Basically, the Danes thought that side planks weren't difficult enough and wanted to up the intensity.
It involves supporting the body weight on one arm and one leg while the opposite leg remains elevated and engaged, creating a brutal isometric hold. This exercise primarily targets the core muscles, including the obliques, transverse abdominis, and rectus abdominis, as well as the adductors, which are the muscles chiefly responsible for bringing your legs together.
Sound a little confusing? Let's get into how to perform them.
How to Perform the Copenhagen Plank
-
Starting Position: Begin by lying on the ground on your side with your legs straight. Place your elbow directly under your shoulder, creating a straight line from your head to your feet.
-
Elevate the Hips: Raise your hips off the ground, forming a straight line from your head to your feet. Your body should be in a side plank position, with your supporting arm directly under your shoulder and your opposite arm resting on your hip.
-
Engage the Adductors: Raise your top leg and place it on an elevated surface, such as a bench or a sturdy chair. Your bottom leg remains extended on the ground.
-
Isometric Hold: Hold this position, focusing on keeping your core tight and your body in a straight line. The elevated leg should be actively pressing into the surface, engaging the adductors.
-
Duration: Hold the position for a specified duration, typically starting with 15-30 seconds and gradually increasing as your strength improves.
Benefits of the Copenhagen Plank
The Copenhagen plank offers a myriad of benefits, making it a worthy addition to any workout routine. Here are some key advantages:
1. Enhanced Core Strength
The Copenhagen plank engages the core muscles to a significant degree, helping to improve overall core strength and stability. A strong core is crucial for maintaining proper posture, preventing injuries, and enhancing athletic performance.
2. Adductor Activation
Unlike traditional planks, the Copenhagen plank specifically targets the adductors. Strengthening these muscles can improve hip stability, reduce the risk of groin injuries, and enhance lower body strength.
3. Improved Balance and Stability
The Copenhagen plank challenges balance and stability by requiring you to maintain a stable position on one arm and one leg. This helps to develop proprioception and coordination, which are crucial for various athletic activities.
4. Rehabilitation and Injury Prevention
This exercise is often used in rehabilitation programs to address adductor-related injuries, such as groin strains. It can also be an effective preventive measure for athletes who are prone to such injuries.
5. Versatility
The Copenhagen plank can be modified to suit different fitness levels and goals. By adjusting the duration, elevation, and position, you can customize the exercise to meet your specific needs.
Variations of the Copenhagen Plank
To keep your workouts exciting and to target different muscle groups, you can incorporate various variations of the Copenhagen plank. Here are some popular options:
-
Knee-Bent Copenhagen Plank: This variation involves bending the knee of the elevated leg, reducing the lever length, and making the exercise slightly easier. It is ideal for beginners or individuals with limited strength in the adductors.
-
Dynamic Copenhagen Plank: In this variation, you perform small, controlled leg lifts with the elevated leg. This adds an isotonic element to the exercise, increasing the challenge for the adductors and core.
-
Weighted Copenhagen Plank: To further intensify the exercise, you can add resistance by balancing a weight plate on your hip or holding a dumbbell in your free hand. This variation enhances the strength-building aspect of the exercise.
-
Extended Hold Copenhagen Plank: For an endurance challenge, increase the duration of the isometric hold. Aim to hold the position for 60 seconds or more, concentrating on maintaining proper form throughout.
Incorporating the Copenhagen Plank into Your Workout Routine
The Copenhagen plank can be integrated into your workout routine in a few different ways, depending on your fitness goals and overall program structure. Here are some tips on how to incorporate this exercise effectively:
-
Warm-Up: Include the Copenhagen plank as part of your dynamic warm-up routine. Perform 2-3 sets of 15-30 seconds on each side to activate the core and adductors before your main workout.
-
Core Circuit: Add the Copenhagen plank to a core circuit that includes other exercises such as planks, Russian twists, and leg raises. Perform each exercise for a set duration (we suggest at least 30 seconds), repeating the circuit 2-3 times.
-
Strength Training: Incorporate the Copenhagen plank into your lower body or full-body strength training sessions. Pair it with compound movements like squats, lunges, and deadlifts to enhance overall lower body strength and stability. We love it as a finishing move after a heavy lower body day.
-
Rehabilitation: If you are recovering from an adductor-related injury, consult with a physical therapist to determine the appropriate progression of the Copenhagen plank. Start with the knee-bent variation and gradually increase the intensity as your strength improves.
Common Mistakes to Avoid
To maximize the effectiveness of the Copenhagen plank and reduce the risk of injury, it is important to perform the exercise with proper form. Here are some common mistakes to avoid:
-
Sagging Hips: Ensure that your hips remain elevated and in line with your body throughout the exercise. Avoid letting your hips drop, as this can place undue stress on the lower back.
-
Rotating the Torso: Maintain a stable and square torso position. Avoid rotating your body or allowing your shoulders to twist, as this can compromise the engagement of the core muscles.
-
Incorrect Arm Position: Keep your supporting elbow directly under your shoulder. Avoid placing your arm too far forward or backward, as this can affect your balance and stability.
-
Inadequate Engagement: Actively press your elevated leg into the surface to engage the adductors fully. Avoid letting your leg hang passively, as this reduces the effectiveness of the exercise.
Conclusion
The Copenhagen plank is a beast of an exercise to target your core and adductor muscles, while also getting you some possibly confused glances in the gym.
Whether you are a seasoned athlete or a fitness enthusiast, the Copenhagen plank is a valuable addition to your training arsenal. Remember to start with the basic variation and progress gradually, allowing your body to adapt and build strength over time.
