BUILT BY PIONEERS, REBUILT FOR TODAY
Long before “AI fitness” was a trend, we were building intelligent training systems with real coaches and real data—helping over 2 million people get stronger. After a decade of learning and refinement, the new GAIN is here: a smarter, more adaptive workout app grounded in real coaching, real science, and real results.
WHAT SHOULD I DO TODAY? SOLVED.
You stop training when you’re not sure what to do next—or life gets busy and your routine gets derailed. GAIN solves both by giving you a clear, structured workout plan built from exercise science, multi-disciplinary coaching, and motivational app design. It saves time, eliminates confusion, and simplifies your entire fitness equation down to one simple, daily action: tap “Start Workout.”
REAL FITNESS INTELLIGENCE
Our homegrown training engine—built with real coaches, not generic AI—unifies strength, cardio, yoga, mobility, and recovery into a balanced plan for daily progress, fully aligned with your body, your goals, and the time and energy you have each day.
ADAPTIVE FITNESS COACHING
GAIN tells you exactly what to do based on your goals, fitness experience, injuries, time, and equipment. Whether you’re at home, traveling, or in the gym, GAIN adapts instantly to your current situation, giving you the right workout for right now.
TONS OF FEATURES, ZERO GUESSWORK
• Simple Design: A clean, single-screen interface that keeps you focused
• Dynamic Equipment: Build workouts anywhere, with whatever equipment you have
• Injury Workarounds: Train safely by isolating healthy muscle groups
• Muscle Heatmaps: Visualize training balance and fill the gaps
• Recovery Routines: Targeted stretching and self-massage to help you rebuild stronger
BUILT ON EXPERIENCE, POWERED BY ADAPTIVE AI
GAIN isn’t another quick-spin AI project—it’s the evolution of a decade of coaching, data, and real-world learning. This is intelligent training, rebuilt from scratch for modern life.

v1.2.1 also includes onboarding upgrades, performance improvements, and a few bug fixes.
Strength Session Picker—Upgrade in Onboarding
We added our 2-level workout selector to onboarding so you can see the power of the GAIN engine right away. Choose more nuanced strength splits like Chest & Biceps, Legs & Abs, or targeted bodypart sessions like Arms or Shoulders.
Email Verification
Okay, this one’s mostly for us. Sorry. We just have to make sure the gym rat is who they say they are these days.
Workout Experience Improvements
Continuing to refine the experience with new sound effects, improved audio ducking, cleaner controls, and smoother content loading—both before and during workouts.
Plan Programming Improvements
GAIN Plan workouts now use more targeted strength splits for better structure, more precise targeting, and just plain variety.
Under-the-Hood Improvements
Parallel equipment loading speeds plan generation. Protocol summaries and warm-up controls are cleaned up like an Equinox locker room.
Bug Fixes
Resolved email verification glitches, a login hang, keyboard layout issues, and several builder screen layout nits.
As always, we’re building quickly, hungry for feedback, and dreaming big about what’s next—while keeping the product experience tight. Be in touch!
