Kiss Your Treadmill Goodbye

Source CBN.com and The Cardio Free Diet

Author and weight-loss expert Jim Karas says you can kiss your treadmill goodbye. He says cardiovascular workouts burn a few calories, but far fewer than you think. From 1987-2000 the number of people exercising on treadmills increased by 900 percent, meanwhile obesity doubled. Using this and other research, Jim developed a new approach to weight-loss: The Cardio Free Diet.

Your body functions like an equation, Jim says, where we look at calories in and calories out. For too long we’ve focused on the first part of the equation when trying to lose weight. Instead, Jim notes that looking at dieting like that is what has led many people to fad dieting. We need to burn calories and interval strength training is the best way to do that for these reasons:
  1. It provides absolute enhanced heart health. It’s our heart-rate variability that counts, how fast we respond to stimuli. If we’re walking at one pace for 30 minutes on a treadmill, our heart rate is at a steady rate. That doesn’t replicate real life. “We live our lives in spurts, not marathons,” Jim says.
  2. Interval strength training provides greater flexibility.
  3. Interval strength training increases lean muscle tissue and increases metabolism. Jim says that we can lose weight doing intervals of cardio exercise also, but that cardio will not build your lean muscle tissue in the same way that interval strength training does. Jim says cardio can be detrimental. “It kills your time, your energy, your joints, and your motivation.” He says the only people who should ever do cardio are those who really enjoy it. Others should cut it out completely.
