Better but still more to go


Content-wise this is my favorite app. Chris Heria is great.

However, the app itself, though it has improved, can get better. I have a list of suggestions.

1. Reduce the length of in-workout exercise videos, only focus on the movement - not the intro or just talking. People want to focus on the workout, not waste time on watching videos.

2. Make each thumbnail for the video specific to the exercise. When it’s just a general thumbnail it’s confusing.

3. It’s very hard to do the workout with the basic timer. Make a rest and an in-set timer. Also have a counter for the rounds.

4. Make even more basic programs/progressions. The beginner program is already hard for the majority of the population. More users will sign up with an easier entry. E.g. the expectation to do 12 leg raises right off the bat.

5. Make the app payable by subscription on Apple. The website looks sketchy and prevented me from buying twice.

6. Basically, throw all ThenX content into a Mad Barz style app.

I’m looking forward to staying on board with ThenX as the app gets better!

Needs to be more beginner friendly


I’m a total beginner to calisthenics and I have no equipment. I was looking forward to this app but when I got to the beginner section I scroll through and find pull ups and tucked Lsits. Idk about other beginners but I can’t do any of that. So instead of getting into the workout I have to go find modified versions of those exercises so that I can participate to the best of my ability. I would have like to see a more beginner program that is still challenging and will build strength and muscle for these workouts but it just seems like it’s tailored to people that can already do these. I’ll still use it but I wish they thought more of beginners who literally just started calisthenics.

Great workouts and improved layout

This app played a significant role in my daily routine the day I downloaded it. It’s great for picking out workouts when you can’t choose them yourself. Problem is that I find myself skipping certain workouts simply because I don’t have a bar to work with. Thenx has done a great job improving their app as it’s less confusing and feels more easier to use.

4/5, turning a door knob has never been a painful task until now.
