Density Hangs, popularized by Dr. Tyler Nelson, are a powerful hangboard protocol used to improve finger durability, tendon health, and resistance to injury. By exposing the fingers to long, controlled loading, the method helps prepare the muscle–tendon system for harder climbing while also supporting rehabilitation and tissue remodeling.

The Hangboard Moving Hangs (HMH) climbing training protocol was described by Eric Hörst in his book Conditioning for Climbers. Because the intensity of the exercise is rather low, even beginner climbers with a couple of months of training under their belt can give it a try.

The Hangboard Moving Hangs climbing training protocol is a perfect introduction to hangboarding, because it’s safe, it puts less strain on the shoulders than typical dead hangs, and it’s easy to do. This routine is a powerful and versatile technique for developing forearm endurance, and it is worth including in any climber’s training portfolio! I started hangboarding with the Hangboard Moving Hangs climbing endurance protocol myself, and I would recommend it to both beginners and advanced climbers.

The Eva López SubHangs strength endurance protocol is characterized by long hang times of up to 45 seconds, at relatively low loads, between 55 – 85% MVC-7. This approach is aimed primarily at improving strength endurance and potentially also strength itself, through hypertrophy. The Eva López SubHangs strength endurance protocol is quite similar to the more old fashioned way of hangboard training, where long hangs till failure were preferred. The protocol can be executed in two versions, the minimum edge with no added weight (SubHangs MED) and with added weight (SubHangs MAW). Use this method if you want to reduce recovery times between sustained sections of a route, or if you need to be able to hang on to small holds for longer!

The Zlagboard comes with a built-in Forearm Endurance Workout protocol. The idea behind the method is to generate a severe forearm pump, targeting the anaerobic lactic energy system and improving both the physiological and psychological tolerance to high acidic loads. While not very climbing-specific, the Zlagboard Forearm Endurance Workout might be just what you need to get you through long, hard, and pumpy cruxes. Boulderers may also benefit from faster regeneration between attempts, as well as from muscle hypertrophy caused by growth hormone release triggered by lowered blood pH. Go ahead and give the Zlagboard Forearm Endurance Workout a try if you like suffering, but keep your climbing goals in mind!

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!

Eva López’s IntHangs protocol is a fingerboard training method for developing finger strength endurance. Two variants—MED (Minimum Edge Depth) and MAW (Maximum Added Weight)—use moderate loads and long time under tension to improve endurance and stimulate muscle hypertrophy.

Classic 7/3 Repeaters use 7-second hangs with just 3 seconds of rest to mimic climbing’s grip–relax rhythm. Their relatively low loads make them accessible for intermediate climbers, while the short rests create a strong pump—useful pre-season preparation for lead climbing.
