They are super slow hit guys. They follow the super slow guru Ken Hutchins method of super slow. Hutchins was a follower of Jones but he put his own twist to it. Using mainly MEDX machines they use light weights using slow motion reps. They train sometimes less than 20 minutes twice a week. That's all the physical exercise they do. I believe they are using less than 80 calories a session.
I personally don't believe super slow involve the muscle fibers that are responsible for the greatest potential for growth and strength. Where in athletics do you do anything in slow motion? When you throw a punch, sprint, or tackle someone do you do it in slow motion? The university of Sydney found that lifting at a one second concentric and one second negative built more strength than the typically preached 3 second up and 3 second down. They found it was 11% more effective. I don't believe in throwing weights as in what I see some people do but lifting in a typical cadence that most bodybuilder use isn't a problem. When it comes to Olympic lifting the more explosive the better.
This subculture of bodbuilding also believe that the added muscle weight put on by super slow will get you ripped quick. They took an accepted given but ran with it to prove the efficiency of super slow. Yes adding muscle uses more calories at rest but give me a break. I guess it didn't work for Hutchins. No offense but maybe due to health problems he looks seriously out of shape in the last picture I saw.
Some of the studies with super slow were gathered from a YMCA in Mass. conducted by a man named Wescott I believe. It showed that non bodybuilders using super slow put on lean body mass but any untrained person put on any lifting program will show an increase in lean body mass.
Lastly from what I heard is that Jones wasn't to happy about super slow or the modifications to his MEDX machines. I think super slow has a place in training. It's a tool like any other. To use it exclusively is a mistake. It's great for rehabilitation.
The guys you see using super slow in the video are hard trainers who are devoted to the system. In the end it isn't rocket science it's just lifting weights.
