OK to be fair...there are some good points about losing weight because of muscle mass buring calories...but that's nutrition 101. The most important point, in my opinion, is long term fat loss (or maintaining weight) isn't best suited by doing cardio.
My Example of this point is the following:
When I was in High School I decided to try wrestling...I had never done it before and at the start of the season I was a tub of goo. I worked my ass off every day doing aerobic excersise (wrestling, running, etc.) and eat a low calorie diet. I went from aprox. 20%BF (158lbs) to around 10% (135lbs) by the end of the season and looked fucking cut.
Over the next 3 years of college I gained it all back plus more because I didn't maintain the strick wrestling regiment. At the start of this summer I started heavy weight training...used some supplements and made some good gains. I've just finished my 1st cycle of sustanon and have lost 3% BF and gained 20lbs on that cycle alone. I am not "massive eating" or anything like that...regular diet (except for protien shakes). Weight lifting may not provide as dramatic results in as short a period of time...but it provides results for a longer period of time and is more practical throughout your entire life.
This is why I don't understand why people tell ANYONE that they should try to lose weight before taking test. If you take test, hit the weights hard and stay on a reasonable diet you will both lose weight and gain muscle! ...this is of course assuming you're not already at peak potential.
OK let the flaming commence!
