A little about myself: I'm a male in my early 30s, I go to the gym a few times a week for cardio, a couple of times a year I'll knock down a 5k in the 10-11 minute/mile range, I play basketball once a week practically year round in an after work league (though my plus/minus is probably pretty bad), my bmi has me as obese and my body fat is north of 20% (had this tested at the gym recently) but I'm not a super-sized tub of goo (5-9, in the 210s). Other than looking terrible with my shirt off I'm pretty healthy. A few years ago I took up running and as of summer 2011 I was down under 190, but then I changed jobs and ruined my workout routine. It wasn't until recently that I restarted the gym habit at a new gym much closer to my new job than the old gym.
My goals would be to lose weight (hopefully faster than before) and build muscle while only being in the gym for 75-90 minutes at a time three times a week. I'm ashamed to admit this but I recently tried to go four days a week on the treadmill and one night of basketball and it had me popping daily Advil just to get through the soreness. Getting old sucks!

I think I have a good grasp of the nutrition end of this. When I'm being good I count calories on my iPhone and do all the recommended stuff: I cook a lot, I shop the perimeter of the supermarket for fresh food, eat only whole grains and no white grains, limit carbs, limit red meat, I don't regularly drink juice, soda, sport or energy drinks (though I'll have a small daily cup of home brewed morning coffee and an afternoon caramel macchiato a few times a week), eat green vegetables.
So does anyone have any experience going from totally un-awesome to less un-awesome? I know the simplest advice is to just get out and move, any exercise is good exercise, but if anyone is familiar with a program with some structure that is targeted for someone with my meager athletic abilities (for example, I tried to do the 100 pushup challenge with some coworkers and after a week or two had to bow out, even the easy track was too challenging) and my limited interest in becoming a gym rat that would be fantastic.
