Real clients have histories. Your software should too.

Build every program against your client's recorded injuries and health profile, see the movements that hurt as they get flagged, and keep each client's whole training record in one place.

Everything you need to coach a real roster.

Body Engineers is built for trainers whose clients arrive with injuries and complex health histories — a structured injury record you actually program from, a health profile beside it, and in-session pain flagging that reaches you.

Program from a record, not a guess

Build each program against the client's recorded injuries and health profile — not a template picked off a shelf.

Injuries in front of you as you build

The client's injury record sits beside the program builder, so the movements they should not be doing are hard to miss.

One record per client

Assessments, sessions, injuries and pain flags live in one record instead of scattered across notebooks and chat threads — the record you program from.

Pain flags reach you, not a void

Clients flag the movement that hurt while they are still standing over it, with a note. You see it on your next look and adjust their next session.

History that does not reset

Every session and every pain flag builds a history you can look back through, with movement screens and body composition recorded against the same client.

Sessions and scheduling

You book the sessions and your clients see what is coming, with the notes from each one attached to the session itself.

Your entire roster.
One shared view.

Review every pain flag, adjust programs, and keep each client's injury history in front of you while you build — all without switching apps. The trainer portal is built for training people who can't follow a generic plan.

The client app

Your clients get an app of their own.

Every program you build lands here, and everything your clients log comes back to the same record. The screens below are how Body Engineers works — not every one of them is switched on today.

On the gym floor

They log every set. You see what hurt.

Session logging built for the gym floor — big targets, zero friction. If something doesn't feel right, they flag the movement and you see it on your next look, with full context.

You and your client

One thread with the people you program.

No lost context in a chat app. Questions, answers and adjustments live where the training does, so you can see what they actually did before you reply.

Marcus Webb · Trainer
Great session today Alex. Your left knee tracking has improved significantly.
Thanks! Felt stronger. Should I still do the Nordics today?
Marcus Webb · Trainer
Yes — 3×8 at bodyweight, and flag it in the logger if the knee talks to you.

Built for the way coaches actually work.

One of these is a real story, from a client trained by a coach on Body Engineers. The other two are placeholders showing the kind of work the product is built for, until more coaches join the alpha.

Half my roster has something going on — a shoulder, a knee, a back. Having the injury record open while I build the session means I am not holding all of it in my head.

Injury-aware training

A coach who trains on Body Engineers took me on as a virtual client after I hurt my lower back. He turned my flare-up into a recovery plan through the app, and I was back to lifting.

Every session and every twinge sits in one record, so I can see a pattern forming before the client can describe it.

If you run a gym and work with clients who have injuries or complex health histories, we would like to talk to you about the alpha.
