Unlock Your Ultimate Flexibility with Stretch Strong! Over 400+ stretching exercises and growing! With search, filtering, and substitution functions, you'll be able to explore a world of flexibility training you can't find anywhere else online! With Jon Call (@jujimufu), a flexibility expert with over 20 years of experience competing in Martial Arts, Bodybuilding, and Strength Sports, you'll get new weekly flexibility workouts created by him (that he does himself!) that you can incorporate into your training. The weekly workouts are quick and effective, demanding only 1 hour per week of total work to see improvements for even the busiest or biggest athletes out there! There are two versions of the weekly workouts: a novice version and an experienced version that you can jump between. 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.
