Copenhagen straight leg (strength)

What you should feel?? When performed correctly, you will feel a “burn” or fatigue build up in the inner thigh and groin of the leg on the block. You may also feel a burn in the under side of your trunk and abdominal muscles.


  • Using a bench or a box that is at least 30cm off the ground
  • Place your foot on the edge of the bench or box and keep the other knee bent and out of the way
  • Squeeze your groin muscles of the knee on the box
  • in order to lift your hips up to a flat position with your torso
  • Ensure you are using your inner thigh of the leg on the box
  • and hold the contraction briefly at the top
  • Repeat until you have finished the set

Main muscles targeted:

  • Adductors
  • Groin
  • Internal hip

Main benefits:

Usually only done with body weight, the Copenhagen is a great way to strengthen the inner thigh muscles which often are neglected when isolating an area. Used for groin and hip injuries at various stages. This isokinetic version is usually a progression from the isometric used for tendon issues but can have various applications. The leg is straightened to add more load to the area than a bent knee version.
