Train with
a plan.
A few short questions, then your week stands: your plan, every set and run, progress you can read, and the people you train with.

A plan,
not a guess.
Tell GROW what you want, how long you've trained and which days you have. You get a full week: exercises, sets and rep ranges, matched to your gym and your level. Change a day, swap an exercise, or build your own plan from scratch.
Your plan.
Every set
on paper.
Each finished set gets its stamp. Last time's weight sits right next to this time's, the rest timer keeps running when you leave the screen, and your Apple Watch counts along. Runs, rides and everything from Apple Health land in the same log.
Progress
you can read.
Your week next to the last twelve. Weeks in a row. Records per exercise. The muscles you trained today. Numbers that answer “am I getting stronger?” without a spreadsheet.
Train
together.
Every workout can become a post, with a poster GROW makes for you. Follow friends, cheer them on, share stories from the gym and pass on plans that worked. You choose who sees each post, and places and routes stay hidden from strangers.

own coach.
Connect ChatGPT, Claude or another AI assistant to your GROW account. Ask it to review your last month, move a training day or build next week's plan. It only gets the access you approve, and you can disconnect it any time in the app.
