Skin-the-Cat

This is the gateway drill for every lever and inversion, because it teaches your shoulders to control load through their full, uncomfortable range with the arms locked. On rings it builds active shoulder mobility and straight-arm strength at the same time, priming the tissues you will lean on for the back lever and muscle-up. Start with a small range and stop short of the deepest stretch until your shoulders feel strong and painless there.

How to do it

  1. 1

    Hang from rings set at about head height with straight arms and a firm grip.

  2. 2

    Tuck your knees toward your chest and pull the rings in as you begin to rotate backward.

  3. 3

    Roll your hips up and over so your body passes between your arms while keeping the elbows locked.

  4. 4

    Lower into a controlled inverted hang until you feel a moderate stretch across the shoulders and chest.

  5. 5

    Reverse the rotation smoothly to return to the starting hang without letting the shoulders collapse.

Tips

  • Keep the movement slow and owned; never fall backward into the stretch or let the rings yank your shoulders.
  • Shorten the range at first and open it up over weeks as your shoulder mobility improves.
  • Keep the arms straight throughout so the shoulders, not the elbows, do the rotating.

Variations

Common mistakes

  • Rings hung above head height leave no floor to touch at the bottom of the inverted hang, so there is no way out if the shoulders start to complain mid-rep.
  • The hands squeeze so hard that the rings cannot rotate with the body, and the wrists get wrung around at the deepest part of the turn.
  • Legs get straightened during the first sessions, which doubles the lever and drags the shoulders further into extension than you chose to go; stay tucked until the tucked range is easy.
  • Hanging relaxed at the bottom to enjoy the stretch hands the position over to the joint rather than the muscle; keep the shoulders pulling and the arms working while you are down there.
  • The return is started with a leg kick, which throws you through the hardest part of the rotation and teaches the shoulders nothing; pull with the lats and retrace the path you came down.

Frequently asked

How many reps of skin-the-cat should you do when you are new to the exercise?
Three sets of 3 to 5 slow reps, two or three times a week, using only the range you could stop and reverse at any point. Holding the deepest comfortable position for five seconds at the end of a set works just as well. Progress by opening the range a little every week or two, not by adding reps, and put it early in a session while you are fresh rather than after heavy pulling.
What can I do instead of skin-the-cat if I have no rings?
A suspension trainer with the handles set high works almost as well, because the straps still let your hands rotate. A pull-up bar version exists, but the fixed grip means the wrists and shoulders cannot turn with you, so it is harder on the joint rather than easier. With neither, build the same range from the ground: a supported German hang under a low bar with your feet still on the floor, a doorway chest stretch, and shoulder pass-throughs with a broomstick or a band.
Why do people do skin-the-cat, and who should avoid it?
It buys active shoulder mobility and straight-arm strength through the deep extension that back levers, muscle-ups, and ring work all demand. Skip it if a shoulder already pinches at end range or has a history of coming out of joint, since this loads exactly that position. It is also the wrong pick if you want a bigger back: it adds range and control, not muscle, so pair it with rows and pull-ups rather than using it in their place.
