### 4/5 — Nice and . . .

*2026-07-13*

I’ve enjoyed doing the stretches.  Nicely laid out, clear, good stretches, etc.  And . . . I wish the exercises weren’t ordered in a way where you’re standing up, then sitting down, then standing up . . . and right now, there is no way to reorder the exercises, although there is a way to decide on the time of the exercise.  Also, I wish there was voice guidance.  As it is, you have to look at the app to find out what’s next.  Hopefully, the new update will have all those improvements.  Also, a renewal rate at the same rate I purchased, or maybe even lower.  That would really be fantastic.  As it is, the renewal rate is higher than I purchased and I know I would not be renewing at that rate.

### 5/5 — Love it

*2024-05-11*

Great app, really helpful has done wonders for my neck and back pain, couldn’t recommend enough.

### 5/5 — Perfect for an amateur at the gym

*2024-05-01*

Have been going for a year now to the gym and don’t have anyone to ask about stretching to improve my next day pains and flexibility. 

Thanks. Truly a worthy app

### 5/5 — Amazing results

*2024-04-20*

Started using this app especially for my lower back pain which I have had for many years. Felt the relief almost instantly with the back stretches. I do these first thing in the morning and feels good for the rest of the day including a good nights rest which I was struggling with. Would highly recommend these exercises which only take a few minutes and certainly worth getting and using the app.

### 4/5 — Want to just Mariana

*2020-07-06*

Weight

### 3/5 — Alright

*2018-12-13*

I got this app so I could add in all the excises from my fav circuit workouts but it comes with its own workouts which is fine for someone who is new to exercise and doesn't have favourite exercises yet. I can't scroll down on the settings page for some reason idk y.🤷🏻‍♀️I still can't find an app that allows me to make my own circuit workouts WITHOUT rest in between.

### 3/5 — Lacking

*2016-11-04*

The app doesn't have pictures or video of the exercises so if you don't know them by name, you either have to sub it for something you do know or stop working out to look it up on the internet. The app also doesn't tell you (or let you choose) how long the entire workout is. The app also doesn't tell you many calories you burned.

### 4/5 — Great but nothing else

*2016-08-03*

Lost 20lbs but nothing special

### 1/5 — Bof

*2015-05-25*

L'application était top avant la mise à jour. 
Le temps de repos n'est pas visible car masqué par le menu du bas!
Bref je ne comprends pas ce que le développeur a fait...

### 1/5 — Interface

*2015-05-25*

What happened to the interface, changed for the worse overnight. Not happy
