I am 21 years old and went through a transformation (body and life) about 2.5 years ago (with the help of the workouts & info from M&S). I was originally weighing around 100kgs (220lbs) when i was 18 and stood at around 5 foot 9...great huh?! haha.
To cut a long story short after learning what to do and not to do when it comes to training and nutrition i managed to drop my weight from 100kgs to 70kgs in about a year and a half.

I began boxing around the same time and this has helped greatly also.

The pump that you get is addictive, combined with boxing i could do it all day long!
