## Program Details

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.
