An article in today's Monroe News-Star really bothered me. The article talks about a man who was severely overweight and had high cholesterol. In his attempt to lower his cholesterol and lose weight, he began to cut out junk food and sodas. I have no problem with this. However his exercise program consisted of strictly jogging.
As we know, jogging and long, slow, boring cardio is not the answer to weight loss. What he should be doing is weight training combined with interval training to promote the growth of lean muscle and decrease in body fat. Lean muscle burns more calories than fat. So, the more you have, the more calories your body will burn. Traditional cardio workouts do nothing to promote the growth of muscle. Check out my previous post on the ill effects of long slow cardio.
The man mentioned in the article did complete a marathon recently in just under 5 hours. I think about all the time he spent training for and completing this marathon. I can't help but think how much better shape he would be in and how much less time he would have spent exercising if he had only been performing 30-45 minute weight lifting and interval training sessions 3 times per week.
He will also probably need to be concerned with the pounding and wear and tear his joints have gone through due to all the long hours of continuous and repetitive jogging. This can lead to many injuries especially for overweight people. Think about this statistic: Every pound you are overweight adds an extra 4 lbs. of pressure to your joints when jogging or running.
If you are considering beggining a jogging program, remember you should never run to get in shape. You should get in shape to run. Lifting weights and interval training is such a more effective and safer method of improving one's fitness.
