Crux Recovery

Crux helps climbers train smarter by tracking recovery, sessions, and injury risk — all in one place. LOG YOUR SESSIONS Track grades climbed, hold types, and movement patterns. Crux calculates your Relative Effort Score (RES) after each session so you know exactly how hard you pushed. MORNING CHECK-IN Log daily soreness, pain areas, and affected fingers. Crux uses this to compute your Daily Readiness and flag overload before it becomes an injury. CLIMBER HEALTH INDEX (CHI) A composite score combining readiness, training load, and injury status — giving you a single number that tells you how ready your body is to climb. RECOVERY GUIDANCE See how many rest days your body needs based on your last session, soreness, and recent training load. Know when you're ready to climb again. INJURY TRACKING Monitor stress load on fingers, shoulders, knees, and more. Get alerts when any body part is approaching overload threshold. PROJECT PROGRESS Track sends toward your project grade and see a projected readiness date based on your current health and training data. TRAINING HISTORY Calendar view of every session and check-in. Grade progress chart over time. 14 and 30 day trend views. Built for boulderers who want to climb harder and stay healthy doing it.
