It really kills me when I sign new clients/competitors up, and they tell me, their last coach had them doing 2 hours of cardio or even more a day!
My question to them and their last coach is WHY??
We all know that to get lean you have to do cardio and have a great consistent nutritional diet. But doing too much cardio can be counterproductive? If you're a slave to the treadmill, or stair master, you can actually lose muscle. Unless your goal is to look like someone who was in a concentration camp, it's best to be really smart about your cardio.
If you don't know how much is too much, let me help!
THE GREAT CARDIO MYTH
There is this horrible misperception in our society about fat loss. A lot of people think that if you starve yourself and do two or three hours of cardio each day, the fat is just going to melt off. Actually, performing too much cardio will put your body in a catabolic state and burn hard-earned muscle. The loss of muscle will not only reduce strength, but it will also slow down your metabolism. If your metabolism slows down too much, you'll have a tough time burning fat, and those are usually the ones who have a horrible rebound when they stop their current fitness regimen.
There's no exact answer for how much cardio is too much. But if you're not a distance runner, anything over 60 minutes per day is likely counterproductive—especially if you aren't consuming enough protein or calories to support the daily caloric expenditure. In order to build or maintain muscle, you need to eat enough food.
I've always said and will always say it, if you have to do two hours or more of cardio a day! Your Diet is not right!
