The Sparticus was tough. Every 3-4 weeks I take a break from my routine work outs and throw in a few weeks of full body compound exercises.

I did the Sparticus work out for two weeks followed by another work out Mens Health outlined that I altered slightly to help tone. I have never sweat like that lifting weights, and it is very intense. I consider myself to be in pretty good shape with a great diet, and I was huffing and puffing during this exercise. You can go slower if you find it to hard, or switch down from 60 to 45 or 30 seconds or something similar.

It isn't something I would continue for months on end, but it would be a great way to burn some fat fast. Remember though your body will adjust to this quickly, you can increase weight and/or switch the order of the exercises to keep your body guessing.

Make sure your diet always matches your work outs, meaning if you are lifting heavy and running lots of cardio, you won't see results unless your diet is equally as intense.
