Invisible Fitness Program

What do you think about this kind of training from the company invisible fitness?

3 set of 60 sec - 3 sec excentric, 3 sec concentric.

You can check out the testimonial and program on this page


let me know what you guys think about it.


Basically, it breaks down to 2-3 sets of 8-12 reps of each exercise with 60-second rest breaks.

According to most strength and conditioning literature, the time under tension for hypertrophy is 40-70 seconds, and this program just reinforces that. They are just doing it in a different way so people will focus on using better form and controlling the weight concentrically and negatively.

It’s just a different spin on the same old thing. :wink:
