How quick and intense workouts can help you get fitter








How quick and intense workouts can help you get fitter

As Tabata?s ensuing paper showed, athletes who do this type of interval training experience tremendous benefits in anaerobic capacity . In addition, high-intensity workouts have also been shown to improve overall conditioning, improved glucose metabolism , and improved fat burning . Why it works And indeed, the power of HIIT lies in its ability to facilitate fat burning, even once the training is done. Part of this has to do with having an elevated temperature. But it?s also because our bodies can?t bring in enough oxygen during these periods of strenuous exercise, creating a kind of oxygen ?deficit.? This results in post-exercise oxygen consumption , or EPOC, and it helps by boosting our metabolism .

Are Long or Short Workouts Best For Weight Loss?






A recent study in the Journal of Physiology compared the effects of a 6-week program on aerobic capacity and fat storage. Just 4-6 30-second sprints interspersed with 4.5 minutes of very low-intensity cycling three days a week, http://www.maxworkoutsexposed.com/how-to-prepare-healthier-food/ increased the usage of fat stores, insulin sensitivity, and aerobic capacity similar to hour-long workouts 5 days a week. While the longer, less intense workouts did show better improvements overall, the sprint-interval training took up only 30% of the workout time and wasn't too far behind. When Longer is Better  For some, a shorter workout session is good news, but there is a fear related to going all-out for older and obese Americans. Rightfully so, those who are sedentary are not familiar with the strenuousness of sprints: the heavy breathing, racing heart, and intense fatigue that it creates could make someone want to stop a workout all together.
