Frequent traveler and this app is amazing

I never leave reviews but this app has been amazing. I’m a 27 year old woman and travel frequently for dance. I felt like dance kept me relatively lean but I didn’t have the shape I wanted. I also got tired of spending money on monthly gym passes in different cities/countries. I got into calisthenics this month to improve strength and felt like the mobility/range of motion would help my dancing.

After a short time, I have visible upper abs and feel so much stronger. They only thing I would love is to be able to swap certain movements for others in the app. I like the no equipment workouts, but would like to swap in some banded movements on leg day for more stimulus. However, I love the current price and understand complicating the app like that might raise the cost. So it’s definitely something I work around and just customize on my own.


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.

My review

I have enjoyed the ThenX app since November. The work outs are great. You can make them as hard or easy as you want. I increase the difficulty by taking 10 seconds between tasks when I can. I’ll be 43 next month and haven’t been in this great of shape or looked this good since I was 20 years old. Thanks.

That was my review 3 years ago. I didn’t know I wrote it. I still stand by what I said then. It must have been 2019. I just turned 46 last month. I still really enjoy the AP. I had shoulder surgery last May and haven’t been able to do everything on this Ap. The AP is still helpful. The community of people are so encouraging. I modify the workouts to manage my shoulder and I’m slowly building myself back up to where I was before my shoulder. I’m still in the best shape of my adult life and love this AP.
