1:1 Coaching
Program Subscriptions
Whether you coach 1:1, sell programs at scale, or run a gym floor, everyone you train uses the same mobile app — built to log workouts, stay accountable, and actually see results. Here's what they get.
A training log they'll actually use. Best-in-class and effortless — your clients log every set, rep, and weight in seconds. Last week's numbers are right there beside them, so they always know what to beat and progress takes care of itself.
Perfect rest, every set. An automatic rest timer kicks off between sets, so your clients know exactly when it's time to load up the next one. No stopwatch, no guessing, no rushing the work that matters.
Every PR, celebrated automatically. The app flags a new personal record the moment it happens — so your clients get to celebrate the win, and you get a built-in reason to reach out and celebrate it with them.
Video on every set. Your clients attach a video to any set, building a visual history of their lifts and sharing it straight to you or the wider community — for form checks, feedback, and a little well-earned showing off.
Nutrition, handled in one place. Track meals against a plan right inside the app, or sync with a favorite food tracker. Training and nutrition finally live side by side, so the full picture is never more than a tap away.
Habits that keep them on plan. Daily habit check-offs hold your clients accountable to the small things that drive the big results — and show both of you exactly where they're crushing it and where they need a nudge.
Progress they can actually see. Your clients capture progress photos over time, then view and compare them side by side. Built-in sharing pushes their transformation straight to any platform — turning their results into your best marketing.
Way more than a training app. Education, videos, ebooks, recipes and more — all your content, organized into hubs your clients can dig into any time. Everything you know, in their pocket.
Conversation built right in. 1:1 messaging, group chats, and community-style rooms — all inside the app. Share videos, images, files and more without anyone ever leaving the experience.
The full picture, in their pocket. Your clients see clear reports on everything that matters — training, nutrition, habits, and body stats — so progress is always obvious and motivation stays high between check-ins.
The most advanced coaching platform built for Bodybuilding coaches. Automate programming, track progress, and scale your business — all in one place.
