Build it once
Write the workout or program the way you always do. Saved workouts, progression rules, the lot.
Cruciferous Greens for trainers.
Program your clients' training in the same free app you use yourself. Build the workout once, send a link, and your client gets the full thing: the muscle map, the exercise list, and a Start button that saves it to their library.
Send the link
Every workout and program has a share link. Text it, email it, drop it in your coaching channel.
They train it
Your client opens the link, saves it to their library, and starts. No account setup on your end, nothing to manage.
Free for your clients too.
No per-seat pricing and no client accounts to manage. If the app earns its keep in your coaching business, consider contributing to keep it free for everyone.
