Coach's note: These formulas are most accurate at 3–6 reps. At higher rep ranges (10+), 1RM estimates get less reliable. Use the Epley number as a training target and verify with a true max attempt in a controlled setting.

TrainSMS programs your sets and weights based on your actual 1RM. Every session auto-adjusts as you get stronger.
