you need this workout app

Probably the best body weight workout app I’ve ever used (of 12ish). Thenx workouts are challenging for people of every fitness level, but the beginner-intermediate-advanced layout makes it easy to pick the right workout for you. Using mostly the “daily workout,” 5-7 times a week (about 30 minutes per day), I saw significant improvements in my fitness and physique after a month or so. (I often supplement with free weights and/or swim.) While you start to see patterns and repeated exercises over time, the workouts rarely feel monotonous (like CrossFit “girls”) and you never see the exact workout twice. Great instructional videos for learning how to build up to more advanced movements. Three areas for app improvement: the warm up section needs a visible clock; rest times seem ignored for the most part (is there an option to set a standard rest period?); and the app tends to reset to the home page if I switch out of the app to change music or something. Otherwise, OUTSTANDING app.

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!

It was good, WHEN it worked but couldn’t log in/support is slow to reply.

We subscribed to the ThenX app several months ago and it worked great. Then one day, we were unable to log into it and couldn’t recover our password. We finally reached out by email to the support group and didn’t get a reply. We messaged Chris Heria himself on his Instagram account and he looked into the issue and finally received a response from support. They were able to recover our account but it said that we didn’t have a subscription. I then screen shot several months of charges from our bank account that ThenX was in fact still charging us but we were unable to gain access to the monthly subscription we had been paying for. So I emailed support back (Cristi is who we’ve been in contact with from the beginning) but never got a reply after that. That email was from July 23, 2019 and it is September now. We were still charged for the month of August and since no one will fix our issue, I had to go and just have my old debit card cancelled to prevent further charges.
