More About Stretch Strong
Most flexibility apps out there are AI abominations with no link to reality or real people. Stretch Strong demystifies flexibility training and has busy people and actual athletes in mind. We make flexibility convenient but also specific. Just search the database for stretches related to your sport or need and try them out!
Stretch Strong has features that help make it incredibly easy for you to continue stretching with a multitude of customizations. With the Stretch Strong app, you can:
– Explore explanations and in-app video demonstrations for every movement in our exercise library of 400+ movements, many of which you've never seen anywhere else!
– Navigate the exercise library with filter, substitute, and search functions to find the stretch you need when you need it quickly!
– Stay updated with weekly videos and notes with the exact flexibility training focus of any given week, as well as the broader context of where we are in a flexibility training cycle.
– Learn with our extensive Tutorial Video and FAQ resource library to help you understand flexibility training principles, techniques, and considerations that can affect your stretching.
– Get a new week of flexibility programming every Sunday with two training tracks: Novice and Experienced.
– Use an in-app training journal with references to recent performance to track your results.

Everything is hidden behind a paywall, maby some cool 1 minute videos but i didnt bother looking, i imagine its good if you wamt to spend £/$90 a month on summit u could do for free with research, this review is for those people as i can imagine its enjoyable other than that

I was excited for this app until I learned AFTER creating an account that it's a pay only app. So now they have my info to most likely sell off. A heads up would've been cool. Or be like most apps and have a Freemium feature.

App keeps saying it needs an update but there's no update available. Won't open. Tried to uninstall it and re-download and I'm having the same issues. On android.

Very nicely made app with a huge library of mobility exercises and a new weekly progression to follow. Easy 5 stars

I'm not paying for a service that I don't know anything about. I understand putting in limitations but you are asking payment for something I hope is good. That's not good enough. Edit: Oh you mean one more subscription for me to forget about? EZ Pass.

I really love this app, but am going to have to cancel my membership because the app is so buggy, half the time I get a frozen screen or a cannot connect to internet message despite having internet.

Great app, highly recommend. One thing that confuses me is it will have 3 sets on the bottom part but the written description will say 4. Not really a big deal just kinda weird.

I am a big fan of juiji. Just wanted to put here it is a subscription based app and there isn't a free version. I can see its probably amazing but thought It least there was a free version. There is a trial version for a 7 days FYI. Just a FYI,

Juji is a good coach and the program works well. It just feels disingenuous to not say that it REQUIRES A MONTH SUBSCRIPTION TO USE AT ALL anywhere the app is mentioned

I compete in powerlifting and I've had so many issues with mobility, especially in my hips. ONE WEEK on this app and I was able to get depth so much more easily and my knee valgus is vastly improved. Absolute miracle and only 15min or so a night.

Great app, love the stretch library and the quick workouts. I just wish I could select a body part or something that was giving me trouble and it would bring up a library of different work sessions to help with that.

Can't access anything about the app without entering payment credentials. Why would I subscribe to a service that I know nothing about? Sorry juji, big fan, but this is BS. I'll never subscribe to something that defaults to charging you after the trial is up. Too many people out there banking off the fact that you'll forget to unsubscribe before the trial is up and they get a free payment for you.

Logged me out twice and despite using a password manager the app states my credentials are wrong. Reset password, pasted same.password in wrong credentials. Agree with other risers app is okay, would like an offline version, more of an indication that it's all paywalled. Also was expecting more of a flexibility progression plan, not weekly exercises that change.

I would love to tell you what the app is about, but I literally cannot even create an account. Ive been trying for 3 days and I get the same error "Unable to process your request right now. Try again later" Im going to find another app to use instead. Edit: 1 month later I tried and I was able to create an account. Still bummed that there isnt a free trial without having to pay upfront. But all good. Also I would like to see stretching recommendations for particular lifts (squat, deadlift, etc)

Love the concept. The UI is terrible. The buttons are hit or miss when it comes to working (currently the app is completely locked because I can't dismiss a "Resume Training" pop up). Other UI elements seem to not load properly but still be "functioning" to the point where it registers certain actions despite not displaying anything - especially with the stretch timer.

I just purchased a 7 day free trial/yearly membership and as soon as I get in the app. I get a "no internet connection" notice and can't use the app. I then tried to reach out to the contact info provided, and got a failure to deliver email. Just want to make sure I don't get charged for an app that doesn't work. I was really looking forward to using it too.
