The rundown

The rundown.

  • 0 1

    AI program builder

    Describe the block in plain English. Trainer Nerd composes a periodized program from a library of 1,272 movements.

  • 0 2

    Kanban program board

    Days as columns, weeks as tabs. Drag exercises between days, edit set schemes, supersets, deloads — native fields, not freeform notes.

  • 0 3

    Coach ↔ client, 1:1

    Invite your coach with a single token. They assign programs from their board straight onto your dated calendar.

  • 0 4

    Calendar assignment

    A template becomes a dated instance. FullCalendar week / month / list views. Disabled days and travel weeks respected.

  • 0 5

    Set logging

    Reps, weight, RPE — logged from the floor. Per-set %1RM and RPE prescriptions, supersets, AMRAP, time-based work.

  • 0 6

    PR history & adherence

    Per-exercise PR curves and per-block adherence — the numbers your coach actually opens in a check-in.

The library, in 3D

Watch the movement.
Not a diagram.

Every one of the 1,272 movements renders as a real model you can spin and inspect from any angle — the way a coach would walk you around the rack. The working muscles light up as the rep moves.

  • Drag to rotate, scroll to zoom — full 360° on the lift.
  • Working muscles glow through the range of motion.
  • Same mannequin you see on every exercise in the app.

A long game

Built for the months between PRs.

For you · solo

Programs that think.

Trainer Nerd reads a one-paragraph brief the way a coach would, then composes a real periodized block — 1 to 14 weeks, your exact equipment, your real schedule.

  • Picks from 1,272 curated movements — not generic placeholders.
  • Respects %1RM, RPE, RIR, supersets, AMRAP, time-based work.
  • Streams week by week — you watch it think.
  • Drops you straight into the editable board when it's done.

With your coach · 1:1

One plan, two roles.

Trainer Nerd is a direct coach ↔ client link — no organization, no roster, no group chat. Your coach assigns programs from their board. You execute. Every logged set shows up on their side.

  • One tokenized email invite. Your coach is in.
  • They edit on the board. You see the updated week on Today.
  • Logged actuals back into their PR history & adherence views.
0 1· Invite

Your coach joins by email.

One tokenized invite. They log in to a coach view; you stay on the athlete one.

0 2· Assign

They write the block, it lands on your calendar.

Programs flow from the coach's board into your dated schedule — no PDFs, no group chats.

0 3· Review

Check-ins built on what you actually did.

Every set you log shows up on their side. Adherence, intensity curves, last-block deltas.

Coach view · the check-in

Reviewing on real data.

Every logged set rolls up into per-exercise PR history and per-block adherence. The Sunday check-in starts from the dashboard, not a memory of texts.
