Pumped

Pumped occurs when a climber's forearm muscles become fatigued and swollen from prolonged exertion. This often results in a loss of grip strength and control, making it difficult to hold onto holds or continue climbing effectively. Managing pump is crucial for sustained climbing performance.

Examples

Sarah was halfway up a challenging route when she felt her forearms getting pumped. The muscles began to burn, signaling she needed a quick rest. James found his grip weakening and his forearms tightening as he climbed the overhanging wall, indicating he was getting pumped. After a few tough problems, Linda's hands started to shake, her forearms pumped from the intense effort.
