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.

Get charged for not even using the app

I download this app hoping it was what I was looking for, I created an account, I saw they had a “My Test Client” pre-made profile by them and you could move around workouts and see how it worked, I notice it said that the first client was free so I created just one with my brother to see how it would work and see how it would look on the other end of the client, sadly it wasn’t what I wanted and since there is no delete my account option I just left it as it is. Today I received an email by them saying I’m getting charged for using the app and for having 2 clients! Are you serious 2 clients?! They are counting the my test client as a client! This is so infuriating when I don’t even use the app at all and they said the first client was free but I am guessing that first client was that pre-made profile by them?? This is so unfair and completely regret downloading this app now. I sent them an email to resolve this and they never replied back. I advice that no one downloads it at all!
