Endurance Repeaters are a less known modification of the standard 7/3 Hangboard Repeaters protocol. The idea behind this method is to perform intermittent hangs until failure, with the load reduced to only 30 – 40% of your maximum voluntary contraction (MVC). Such training is known to introduce adaptations, which include improved capillary density and vascular conductance, increases in size and density of the mitochondria, aerobic enzymes and fat oxidation, as well as sparing of muscle glycogen, reduced rates of lactate (La-) production and enhanced La- removal. Ultimately, you should expect improved oxygen supply to the muscles and better maximal endurance capacity. Give Endurance Repeaters a try if you often get pumped before you even reach the crux on those long sport routes!
