ChatGPT talks
You've got a
body to train
Let's go

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. Ohunjal reads it instead: sessions become reports, reports become growth predictions, and your AI coach talks to you about what actually happened. 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 you can generate 1 AI plan free, plus keep 1 saved plan. That is enough to see how it asks, what it builds, and whether the two of you get along. Session reports, growth predictions and the AI nutrition coach sit in Premium, because those features need history to mean anything. Taste you can judge in one session. Compounding you have to stack.

Ohunjal AI does not write sentences. It calculates prescriptions. It runs on rules built from ACSM and NASM guidelines and reviewed by KNSU exercise science PhDs, designed hands-on by a trainer who coaches real clients. Every exercise carries form cues, and rest between sets shows the ACSM-recommended value. Tell it how your body feels and how much energy you have, and intensity and set count adjust to match. Anything that feels wrong, you swap yourself for another exercise in the same muscle group.

A trainer's real job is fitting the work to you, and that is what Ohunjal does too, rebuilding every session around your condition, time, equipment and goal. 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. Costing $4.99/mo instead of $75-100 a session is honestly the second reason.
