What's New


We fully upgraded the workout experience, developed from over 2 years of extensive testing and iteration.

These bigger/faster/stronger apps will also include:
- A fresher audio-visual experience
- Major performance improvements (no more “loading” issues)
- Hand-crafted workouts from expert trainers (no more algorithms)
- More exercises for FREE (no more premium “expansion packs”)

These changes mark our renewed focus on the self-guided workout apps—they will benefit from increased attention and continuous improvement going forward.


In order to streamline and simplify our apps, we removed some of the less popular features from our previous app versions. Namely, versions 8.0 will no longer offer:
- Algorithmic workout building
- Workout buddies
- Workout history (initially)
- GAIN Plan (we'll bring this back, but in a different way)

While it’s difficult to cut features, we are confident that this simplification will create a better app experience for GAIN users going forward.

NOTE: You may choose not to upgrade to this version in case you really want to maintain your existing workouts (and not get access to all the amazing, fresh, new workouts and content coming down the pipe). If you go this route, you will no longer be able to generate new workouts or plans, but you WILL be able to access all your existing workouts. It's. Your. Prerogative.

Keep on,

The GAIN Fitness Team
