High Intensity Interval Training, which is also abbreviated as HIIT, is a form of cardio where you go all out for a short period of time, and then rest for a while, repeating this cycle multiple times. Numerous studies have shown that HIIT is actually far better for fat loss, and overall health, than steady state cardio. And, you can save time doing it.
Sure, you can lose weight quickly. There are plenty of fad diets that work to shed pounds rapidly -- while leaving you feeling hungry and deprived. But what good is losing weight only to regain it? To keep pounds off permanently, it's best to lose weight slowly. And many experts say you can do that without going on a "diet." Instead, the key is making simple tweaks to your lifestyle.
When Johns Hopkins researchers compared the effects on the heart of losing weight through a low-carbohydrate diet versus a low-fat diet for six months—each containing the same amount of calories—those on a low-carb diet lost an average of 10 pounds more than those on a low-fat diet—28.9 pounds versus 18.7 pounds. An extra benefit of the low-carb diet is that it produced a higher quality of weight loss, Stewart says. With weight loss, fat is reduced, but there is also often a loss of lean tissue (muscle), which is not desirable. On both diets, there was a loss of about 2 to 3 pounds of good lean tissue along with the fat, which means that the fat loss percentage was much higher on the low-carb diet.
How does it work? The Shred Plan is based on “diet confusion.” This principle is modeled after a similar strategy in exercise called muscle confusion, which is used to help break through plateaus of muscle growth. When you do the same types of exercises at the same times, your muscles acclimate to the stress and your progress stagnates. Muscle confusion dictates that people work their muscles in different ways for varying durations of time. By “confusing” your muscles, you can trigger their sustained growth and continue to move toward your fitness goals.
1. Bicycle Crunches are a great ab exercise and work the abs from every angle. It’s a combination of the regular crunch, a side-to-side motion that hits the oblique muscles and a reverse crunch that targets the lower abs. You can change the difficulty level by increasing or decreasing the range of motion used and the speed of movement as well as the intensity of the crunch by holding and squeezing.
In a way, moderate-intensity physical activity is that "magic pill" a lot of people are looking for, because the health benefits go beyond keeping your waistline trim: Not only can it reduce your risk of cancer, stroke, diabetes and heart attacks, but studies have shown that physical activity can significantly improve the moods of patients with major depressive disorders.
