User reviews

Very limited

Initially, I was quite impressed with this app. It effectively demonstrates proper form during exercises. However, it’s not suitable for long-term use due to its limited exercise library. For instance, if you’re looking for shoulder exercises, there are only a few options available. Similarly, there are only a few exercises for biceps. Regrettably, I purchased this app for an entire year, but I’ll only be able to use it for about six months. I’ll have to switch to another workout app that offers a wider variety of exercises.

EXTREMELY IMPRESSED

I’ve been lifting on and off for years. I had a break and wanted to try something new. This app is insane in the best way. They literally thought of everything. LOVE IT!!!

Decent app - would prefer monthly subscription

The app is decent but I would prefer a monthly payment option instead of yearly.

Excellent

Life-changing. Kudos to Jeremy and team. Wife and I have loved the app and have lost a ton of weight so far while building muscle.

Suggestion : add blue progression arrows to Apple Watch so I don’t have to go to my phone to see what to adjust for my next set.

Gained 4lbs of fat and lost 1lb of muscle in my first 2 months

I didn’t keep to the calorie guidelines but hit my protein goal and exceeded most days, was on calorie surplus and was consistent with workouts and effort level, and after 2months my dexa scans say I gained 4 lbs of fat and lost 1lb of muscle. The only change I made over the last two months was downloading this app
