Man, when I trained Sebastian the prowler didn't even exist so you are confused, I never used the prowler with him. I might have mentioned him in the video, but sometimes I confuse the names of the guys I trained.
The guy I used it with was another amateur bodybuilder, who was also very good but decided to stop competing. I also used prowler work with Daryl Gee when I trained him for the olympia. He did zero "traditional cardio".
As for the specifics of the workout, I can't always give out complete programs to everybody, especially since that prowler "program" is about 3-4 years old, so I do not remember it.
It was probably something very simple like 6- 8 sets of 30m pushing forward and 6-8 sets of 30m pushing backwards.
