Customer Reviews

So happy I found this app

This app is really great! It has a whole workout program or you can look up individual workouts yourself. Customer service is VERY kind and quick to respond. I was very impressed with them and will be recommending this app to everyone

Good, but not all free

This app is really good, and with the one thing it gives you, there are really great exercises. The only problem is there are so many buttons on the app and you can only use one thing for free. I personally don't care too much, I think the one is enough.

Liked it so much I purchased the full version

"Instant Butt! Instant Butt!" is the mantra me and my workout buddy chant when getting our arsenals kicked while doing workouts from this app.

I downloaded this while in search of free fitness apps that would focus on toning my thighs and butt. (Mostly butt.) it had so many different kinds of workout for that region of the body alone that I had no trouble putting together a little butt-focused fitness plan of my own with plenty of varied movements to choose from. This isn't so easy to do sometimes because I strongly prefer body weight-only exercises so that I don't have to rely on weights or machines at the gym, but with this app I got exactly what I needed!

You have dozens of workouts to choose from that utilize different ways of resistance training. Every exercise has photos for each step and brief explanations for every part. You might need to look them up again (or just mark them as favorites) if you don't remember their names, but it's not hard to understand what to do.

I couldn't do this with a different free app by a different company (which had way way less exercises and no animated photo guides, just a single illustration - still good for a free app tho), I wound up buying the full version, Instant Fitness. For just $3, I figured it would be more than worth it, plus I want the app makers to get rewarded for their hard work.

Thanks guys! Instant Butt!
