The fitness app I have been SEARCHING for

I need to preface with the fact that I rarely ever write reviews. This would be my first for an app actually. I would say I’m considerably fit, and whenever I try out a fitness app I’m typically disappointed because they treat everyone like a beginner, or the movements never really get harder.. etc, etc. I have been looking for a program that pushes me, and develops my strength in an efficient and functional way. I have been meaning to try a calisthenics program for a while, and this has been amazing. I bought the membership within two days of having the app, and have been excited to do the workout of the day. It’s great because you can signify your level, and the amount of resources the app has outside of specific programs, are wonderful. And the quality is A1. I’m SUCH a fan. Go get this app. Now!


Incredible workouts, poor app

Let me start off by saying Thenx is great. Out of all the paid subscription based fitness plans I have tried out, this one takes the crown as being miles ahead of all of the rest. I’ve been using Thenx for two months now, and the results are undeniable. The app itself is the only thing I have an issue with. The design of the app is great, it has a very clean well put together UI, it even shows videos of each exercise when prompted to begin the workout. However the app is CONSTANTLY crashing. I find myself having the keep my phone open at all times during the workout and always on the app because of I were to turn the screen off on my phone or go out of the app for any reason, the app will crash and you have to re open it and start all over again with your workout. On top of that, I’ve sometimes had trouble with even opening the app and loading up the workouts themselves. As I said, this does NOT discredit the program itself as it is elite, but the app needs some fixing.

Fantastic offer and amazing content - also for free-version users!!

For anyone looking to get started or change up their routine, THENX is perfect for you. Most of the exercises can be done anywhere - at home, outside in a hotel room or at the gym. I‘ve been doing fitness and working out for decades now, but the workouts, progression moves and explanations here have taken it to a new level. Much of the content in this app is free, and there are no annoying ads either. So there are no excuses not to download it and give it a whirl. You won’t regret it. There’s a daily workout posted (as the title suggests) everyday - and for three fitness levels: beginner, intermediate and advanced. I rarely write reviews, but this one is more than worthy and deserves a good one. Thanks Chris and all the folks at THENX for this. BTW, the workout pants (THENX Jogger II) are amazing!
