Hi everybody,
I just wanted to have some informations to understand well the programm. It is written on level 15 4x4 sets and 5sec at reps/time. I don't understand how to execute it well because the video shows a number of reps and not a tipe laps.
I saw the exact same thing on level 20.
Thanks to help me.
Please watch the explaining video !
I did it. That's why I'm asking. I just see you doing reps, so I don't understand why it's written time and 4x4 as sets.
I think it means you do it twice on 1 leg for 5 seconds (hence the 4 for both legs I guess) for 4 sets (4x4) if I'm not wrong, like with left leg 5 seconds, with right leg 5 seconds, left and then right again, that's the only sensible thing..
