2019-02-22 00:00:00 ! attention - the app works only on android 7.0 and higher. Ratio - stroke / recovery = 1: x. Example: you need ratio 1: 3 - Input "3" into the "ratio" field I am a rowing coach, I hope this app will help both young oarsmen and coaches. 3 stages of recovery (blue squares) you can fill with your own patterns. i use such a circuit: 1 stage - straight arms, 2- half of slide, 3- full slide.
