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.

About

Plateline

Features
Read full description

Plateline is a strength training tracker built around one idea: logging a set should take one tap. Finish a set, tap once, and the weight and reps you did last time are already there. The rest timer starts itself. Your next target is on the row in front of you, so you never have to remember what beating last week means. LOG ANYTHING YOU ACTUALLY DO A catalog of 136 movements ships with the app, and each one collects only the fields it needs. A barbell lift takes weight and reps. A plank takes a duration. A rowing machine takes distance and time. Assisted work takes a negative load. Add your own movements when the catalog misses one. FROM THE LOCK SCREEN A live session puts the current set on your Lock Screen. Complete it there, without unlocking the phone and without breaking your rhythm between sets. ROUTINES, NOT PAPERWORK Build a routine once and start from it. Edit the day as it actually went, afterwards, in History. Nothing is frozen once it is written. PROGRESS YOU CAN READ Volume, working sets and estimated one rep max per movement, drawn from the sets you logged. The estimate stops above twelve reps rather than print a number that would bend the trend line, because the Epley formula is fitted to low rep work. BUILT FOR THE GYM Dark by default, so it does not blind you at 6am. Portrait only, one handed, with a keypad sized for the phone you are holding. Haptics confirm a tap you cannot look at. Undo is always one tap away. YOUR DATA STAYS ON YOUR IPHONE There is no account, no server of ours, no analytics and no advertising. We cannot see what you lift, because none of it ever leaves your device. FREE AND PRO The free plan covers two completed workouts a calendar week and two saved routines, with the full catalog, history and progress. Delete a workout or a routine and its slot is free again. Everything you have already logged stays readable and editable whether or not you subscribe. Plateline Pro removes both limits: 3.99 USD a month, or 29.99 USD a year. A one time Lifetime unlock is offered as well, at the price shown on the paywall. Prices vary by storefront. Payment is charged to your Apple Account at confirmation of purchase. A subscription renews automatically unless it is cancelled at least 24 hours before the end of the current period, and your Apple Account is charged for renewal within 24 hours of the end of that period. Manage or cancel a subscription in the App Store settings of your Apple Account.
