How to do it

  1. Lie on your side on your forearm, top leg on a bench.
  2. Lift your hips and hold your body in one line (reps = seconds).
  3. Knee on the bench is easier than your ankle.

Pick a weight you can lift for 15 to 40 seconds with good form, and stop each set with a few seconds left in the tank. Do the same number of reps on both sides, starting with your weaker side.

Why rating B

Static version of the Copenhagen adduction: good to start with or as an extra. The evidence (Harøy 2019) is for the version with reps, and a hold is hard to progress; hence B.1

Mitta rates every exercise from S to C, based on research where it exists and on how the exercise loads the muscle. When Mitta builds your plan it picks from S, A and B exercises and prefers ones that load the muscle at long length. C exercises are never picked automatically, but you can still choose them yourself.

Alternatives

These train the same muscle. Use one if you lack the equipment, if this exercise does not feel right, or for some variety.
