Log every set as you lift — weight, reps, RPE, rest and tempo. GYMJAM turns raw sets into estimated 1RM, personal records and weekly volume, so progress is measured, not guessed.
Record load and reps for every working set, plus tempo and rest period when you want to control execution and recovery precisely. The tracker keeps a running total of session volume as you go.
Log RPE per set to quantify effort and autoregulate intensity across a training block. RPE data sits alongside load so you can see whether a lift is getting easier at the same weight.
Live elapsed time, set completion and rest tracking keep your sessions honest. Start a workout on your phone, finish reviewing it on the web — everything stays in sync.
ESTIMATED 1RM
GYMJAM estimates your one-rep max from each logged set using the established Epley and Brzycki formulas. Strength trends are tracked automatically, so you can drive progressive overload from data instead of feel.
