A personal trainer
in your pocket

In most apps your log is where data goes to die. You write down 60kg for 10 reps and nothing ever comes back. A YouTube video does not even know you exist. OUJ reads it instead: sessions become reports and reports feed growth predictions. It remembers the last weight you lifted on every exercise, so you start there next time. Your log does not pile up. It comes back to you.

Sign in and get 10 workouts free. One is used each time you start a workout, and you can finish all 10. You can also keep 1 saved plan. Session reports, growth predictions and AI nutrition coaching sit in Premium, because those features need history to mean anything.

OUJ does not write sentences. It calculates prescriptions. It runs on rules built with reference to ACSM and NASM guidelines, designed hands-on by a trainer who coaches real clients. Rest between sets shows the ACSM-recommended value. Anything that feels wrong, you swap yourself for another exercise in the same muscle group. If you are in pain or under treatment, check with a professional first.

A trainer's real job is fitting the work to you, and OUJ builds plans around your goal, equipment and time too. The difference comes after. What a trainer adjusts in the room mostly disappears with the session. Here it stays: every weight, every completed session, every trend compounds in your account and returns as reports and predictions.
