Build aerobic capacity and forearm endurance through continuous climbing
Based on scientific research, community feedback, and proven results from climbers at your level.
Aerobic Restoration and Capillarity (ARC) training develops the foundation of climbing fitness. Through extended periods of easy climbing (20-45 minutes), you build the capillary density and aerobic capacity needed for recovery between hard efforts and sustained climbing performance.
Essential for sport climbers and an often-overlooked component of boulder training, ARC work builds the endurance base that supports all other training.
