Ok, you will get alot of conflicting advice on this, even on this site. For the sake of argument you use this example. You have a 23 year old weight trained male. Squat 350 Bench 275. 17% bodyfat. Is on a diet that will meet his BMR or over by 100 calories or so.
Whatever he loses it will mostly be because of whatever energy expenditure he does. Now for the question. Is low intensity cardio or interval training the better choice for energy expenditure. Now we are mainly concerned with body composition so not so worried with the neural implications of low intensity exercise unless it hurts lean mass maintainence. Anyone?
