For certified personal trainers, group fitness pros and fitness leaders who want to train others.

GAIN for Trainers is the simplest, most effective way to digitally train your clients (and groups) outside of in-person 1:1 or group training sessions. Create, save and send personalized workouts, manage a client’s schedule, stay connected and hold clients accountable 24/7 through messaging and real-time progress notifications.

This app works in conjunction with our companion app GAIN Personal & Group Training.

GAIN for Trainers features the most extensive and varied exercise library on the market. Choose from over 1,700 exercises covering diverse modalities such as free weight and machine strength training, functional training, bodyweight training, Cross Fit, Pilates, yoga, TRX, corrective exercise, cardio, agility, plyometrics, mobility, and tons more. Each exercise includes motion GIFs and audio instructions—created by pro trainers and demonstrated by trainers and fitness models.

NOTE: If we’re missing an exercise you want, please let us know.

Our workout builder has been lauded by top fitness clubs around the world as the most easy-to-use for trainers to create completely custom workouts from scratch. Templates allow you to save and store full workouts or segments (i.e. warm-up, cool down) for future use. Drag-and-drop features allow you to program straight sets, circuits, pyramids and supersets. You can even intersperse cardio with strength training, rehab exercises, stretches and yoga poses. We give you nearly complete freedom—so get creative!

NOTE: We do not yet support AMRAP, AMAP or Complexes, but let us know if you’re interested in these advanced protocols.

The Group Training feature is currently in Beta, and we are not charging anything for it yet.

What's New

Version 1.1.0

Group Training (Beta) – Now you can build and manage training groups using the same powerful programming and accountability tools you use for 1:1 clients. Groups allow you to invite an unlimited number of clients to a single training program and batch together progress notifications and messaging into one feed per group. Now you can scale your virtual training business from 20-30 clients to massive virtual training communities.
