There are several methodologies you can hang with. Personally I think it depends on how long it takes your unit to reach fatigue with the weight. Obviously you don’t want to increase weights to dangerous levels, and you don’t need to. You just need to be able to reach fatigue in the ligament or tunica, whichever is your current primary limiting factor. Then you can even lower the weight and ride the fatigue for longer periods of hanging. Re-induce fatigue and repeat when needed.
