Frequently Asked Questions

RPE stands for Rate of Perceived Exertion. It's on a scale of 1-10, where 1 is very easy and 10 is maximum effort. We use it to help you gauge how hard a set felt, which helps us suggest appropriate weights for your next session.

We use the Epley formula, based on the top set you log each session — the weight and reps you get for your best set. It's an estimate, not a lab test, so day-to-day variation is normal. Look at the overall trend over time rather than any single number.

We look at your most recent session for that exercise. If you hit the top of your target rep range comfortably, we'll suggest a small increase. If you were under your rep range or it felt very hard, we'll suggest holding at the same weight. It's a starting point — always adjust based on how you're actually feeling that day.

If an exercise isn't available to you (equipment, injury, personal preference), this finds a substitute that targets the same muscle group and movement pattern at a similar difficulty. On the free plan this is available a limited number of times per month; Pro removes that limit.

After a run of consistent training weeks (you choose how many, in Settings), we'll nudge you to take a lighter deload week. This helps manage fatigue over time. It's just a reminder — training through it is entirely your call.
