Haha, hey join the crowd. A few things I have learned by accident over the years.
Dieting and or food intake is gonna be the most important thing in losing fat mass, but really, the slower you lose it, the more lean mass you will keep and just lose mainly BF. If losses are to quick, one can lose maybe 35%-45% lean tissue mass along with BF.
As far as rep ranges etc., it was always more higher rep multi sets, back in the day, 3-5 sets 8-12 rps, but it certainly may vary among certain genetic types. (whether or not you have a propensity to be lean or thick!?)
Of course again bigger compound exercises working the largest muscle groups and building/burning/ better hormone release etc. and as much energy will produce and or elicit the biggest body changes, ie: 3 sets of squats or clean & presses, will do much more than 7 sets of curls or tri kick backs. Cardio work thru the week cannot hurt either.
Hope that sheds some light!?
BTW, what did you play?
