Muscle map

Tap a muscle. See what trained it.

Templates and plans

Plan it, do it, compare.

Build templates and planned days with sets × reps @ weight. When you train, Heza shows planned vs done, so you know whether you hit the session. Your AI can plan the week for you.

A week planned by your AI: Monday Upper A, Tuesday easy 6 km run, Wednesday Lower A with squats 4 by 6 at 82.5 kg, Thursday 8 km tempo run, Friday rest, Saturday 14 km long run.

Coaching

A second pair of eyes on your training.

Connect your AI and it reviews your sessions: volume, loads and how lifting fits around your runs. It leaves a coach note on the Lift screen with one next step.

How the AI coach works
Coach note from your AI in Lift: Three sessions a week and loads are still climbing. Bench is up 2.5 kg in three weeks and squat volume held steady despite the long runs. Suggestion: Keep Wednesday's lower session before Thursday's tempo.

FAQ

Workout tracker questions.

How are the suggested weights worked out?

From what you did last time and how hard it felt. If you did 3 sets of 10 at 25 kg with 2 reps in reserve, Heza suggests 27.5 kg. If a set was a grind, it suggests holding or dropping the weight.

Can I log effort?

Yes. Log reps in reserve (0 to 4+) or RPE with one tap per set.

Does it work for single-arm moves and planks?

Yes. Log per-side sets and timed holds as well as regular sets.

Does Heza count lifting calories?

Yes. They come from your watch when it recorded the session, or Heza estimates them. You choose whether they count toward what you burned.
