I have found heavy workouts, esp with a lot of leg work burned more fat than anything. I am sure if I wanted to dedicate more than an hour or so to training cardio may surpass that in the long run....but I don't have time like I did to spend 4 hours+ a day training.
Nowadays when I want to get back in shape I stick to a 3-5 day a week plan (right now I am doing 45min workouts, total body 3x a week...5x a week 1 hour workouts on a split I find more gains)
I do pushups, bent rows, good mornings, curls, tri exts, military presses, upright rows, squats, side bends, crunches and leg raises. Quick home workout.
I also supplement currently with ephedra (now with guifaisen 🙁), caffeine, a little aspirin, magnesium, potassium, a good multi-vitamin and lechitin. I eat two pretty well balanced meals (pita with tuna or chicken and vegetables for lunch, 4-6oz of a meat and more vegetables for dinner...during the weekend anything goes).
For the last 20 days I have lost 1lb per day. I want to lose another 10lbs (get to 175lbs at 5'10.5").
