I'm not familiar with this method!

You will get ripped really quick! The premise is that you do intense excerises for a minute at a time and then rest for a minute then increase intensity for another minute or 2 then rest, so on and so forth! Look into "Insanity!"

Ooooh. I started experimenting with something like this... with a intense pushup routine..

Still suck at it but gettting stronger..!
