About MyRX - Fitness Workout Tracker
MyRX turns your own numbers into your next step. Log a lift, a run, a night's sleep - and MyRX tells you what to do next, backed by sports science. STRENGTH - Every set projects your rep maxes across the full rep max range, so you always know the weight to train next. Powerlifting, CrossFit, Olympic lifts, bodyweight, strongman - it's all here. CARDIO - Pace and heart-rate-anchored zones for running, rucking, rowing, the air bike, stairmill, swimming and the Concept2 ergs, so you train at the right intensity to get faster. SLEEP - See your sleep rhythm across the week and get next-step guidance to recover for what's coming. HYDRATION - A daily water target built around you, with a fast way to log every intake. NUTRITION - Track your macros against a daily calorie target tuned to your goal. HEART & RECOVERY - Resting, average and peak heart rate by training zone, synced from your wearable. YOUR TRENDS, ONE PLACE - Strength, cardio, sleep, hydration, nutrition and bodyweight all trend toward your goal, and every screen answers one question: what's my next step here? Free to download.
