I suppose the downloaded field that I have on my phone, which is called The Leg Day Automated Workout is this one? 
Edit: it has to be.
Yep, it is, checked the YouTube field for comparison.
I felt like a pressure or something and pulsating sensations in my feet and heels, also in my calves too, it’s definitely working and the sensations are clear and strong.
It kind of feels like a massage.
