First of all, I know that the term cardio is not necessarily an acurate one, but we all know what I'm talking about! My question to all of you out there is what are your thoughts on cardio? I've heard so many conflicting opinions out there that I don't know whether or not a few 30 minute runs a week will reduce me to 98lbs or give me a red afro! I'm a pretty solid 190lbs at 5'8 but I just want to tighten up my stomach and bring out the definition in my chest and back.
My training program is pretty sound I think. I train three times a week on the big exercises such as bench presses, overhead presses, trap-bar deadlifts, power cleans, bent rows, chins, squats, and curls. I split these exercises logically over three training days. I don't really do too many arm exercises or shoulder raises or anything because I really find they get worked hard enough for me from chins and pressing movements.
Since my cardio has been essentially nothing other then the odd game of hockey or something every few weeks, would the simple adding of a 30 minute jog in between training days as well as a masive reduction in sugar/junk foods get me where I want in a few months? I'm already in decent shape, just have a little gut and lack definition. Any thoughts or advice?
