The Maximum Weight “7-53” protocol is a highly effective strength training method developed by Eric Hörst as something in between the classic 7/3 Repeaters protocol and Eva López’s MaxHangs. This highly time efficient protocol is the middle ground between strength and strength endurance training, and it is recommended for intermediate and advanced climbers. With this method, Eric progressed from 22.5 kg to 41 kg added weight on a 14 mm edge and it’s his favorite hangboard protocol!
