One Rep Max
Estimate your 1RM from a submaximal set. Enter the weight you lifted and how many reps you got — the calculator does the rest.
Clinical Context
If you're on beta-blockers or other heart rate-affecting medications, percentage-based programming may still work for you — but RPE (Rate of Perceived Exertion) is often a more reliable intensity gauge. Check out our RPE to Percentage chart for an alternative approach. If your blood pressure is uncontrolled, get clearance from your physician before testing maximal strength.
