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.

Stay Safe in the Sun!

Playing in the sun

Hot, sunny weather can be dangerous. We enjoy exercising outdoors, but high temps can be dangerous without proper precautions. Experts at the American Academy of Orthopaedic Surgeons recommend lowering your risk of heat injury. Keep their tips in mind when you play outside:

  • Drink plenty of water. Don't wait until you become thirsty — keep yourself hydrated throughout your workout.
  • Take breaks, especially if you're trying a new activity or if you weren't active during the colder months.
  • Schedule your workouts in the morning or evening, when it's cooler. Avoid working out during the hottest part of the day — between 10 a.m. and 4 p.m.
  • Slow your pace on hot days. Your workout may take longer, but heat exhaustion can come on quickly when you exercise at an intense pace. Take it easy!
  • Wear lightweight, breathable fabrics; light colors will help reflect the sun's heat.
  • If you suspect heat exhaustion, stop what you are doing immediately. Move to a shaded area, remove excess clothing, fan or wet your body to reduce your core temperature, and seek medical care immediately.

Keep safe outdoors, and stay cool this summer!
