Select your goal to see suggested weight ranges based on your estimated 1RM. Strength targets 1-5 reps at 85-100%. Hypertrophy targets 6-12 reps at 65-85%. Endurance targets 13-20+ reps at 50-65%.

How many reps you had left before failure. RIR 0 = you couldn't do another rep. RIR 2 = you could've done 2 more. This helps estimate your 1RM and track intensity.

Tick the warm-up checkbox on lighter sets. These are excluded from your working volume totals so your metrics reflect true training stimulus.

Uses the Brendan formula to estimate your 1RM from a working set, then shows what weight you should be lifting for different rep ranges. The suggested range highlights your selected goal zone.

Total volume = sets × reps × weight (working sets only). This is a key driver of training adaptation.

Use the floating timer in the bottom-right corner. Tap a preset or type your own rest period. The timer will beep when time is up.

Copy your session report to save it in your notes app. Next session, paste it into the Import section to pre-fill your exercises — then adjust weights and reps as you progress.
