The metabolic effect of an hour of cardio is 3-4 hours while an hour lifting hard is 8-10 hours.
Increased muscle increases testosterone. You will also find out once you lose your weight your testosterone will increase somewhat which will help keep the weight off as excess fat decreases testosterone production.
Cardio is very important for cardiovascular and joint health and you need to do it also and I try to do it 5-6 days per week.
Seriously, thanks for the input. I am doing the TKD twice a week. I have incorporated the “Couch to 5K” program into my routine also. I need to up my cardio endurance. I am planning on testing for my black belt in about 1 1/2 years and at 51(age now) I am really huffing and puffing. To go through that test I need to be in really good shape. I would like to add some weight training, but finding the time is difficult.Up to now “weight training” has consisted of lugging my fat $#s to the fridge.
