'Milo' is the best periodical that I've run across on strength training, which is different than 'body building'. A lot of feats of strength involve muscles and connective tissue that you don't see from the front, like hamstrings and back, but you'll see most males in the gym spending lots of time doing curls and bench presses. Too much time looking at 'Muscle and Fiction' on the magazine stands I guess. One article in Milo that I recall was by a strength trainer at Johns Hopkins, who recalled that at one time the 'ego lift' was the standing military, where 200 lbs seperated the men from the boys. I'm still a boy I guess :^) He observed that among the people that he trained the ones who could do 300 lbs on a standing military press all could bench 400 lbs even though they didn't train at bench pressing, but people who benched 400 lbs and didn't train with the overhead couldn't do 300 lbs. The standing military evidently provides better 'transfer of strength' to other activities, like chins do over pushups.
I have come to prefer a basic 'core body' program, around squats, different deadlifts, standing military, chins, and sometimes additional grip or 'foo foo stuff' like rotater cuff or curls, all with free weights. For fun I like to do cleans and clean and press. I use to alternate days of cardio and strength but when time got short I combined them into a routine of cardio, stretching, and weights. From my observations everyone does some sort of deadlift often, be loading groceries in the car, bags on concrete in the truck, puting sleeping kids in bed, etc., so by making sure that your daily activities are less than the stress that you apply in the gym you'll avoid back problems. I also find that grip work, like a farmer's walk with a body weight of dumbbells, holds carpal tunnel at bay.
The tough balance is between weights and cardio, as the Marines taught me that you always have to be able to do the runs.
