For this HIIT 100s program, I've combined HIIT not only with weights but also with two very popular, intense, and effective weight-training techniques: German volume training (GVT) and Hundreds training. With GVT, aka 10x10, you do 10 sets of 10 reps on a given exercise. Hundreds, as the name implies, involves doing 100-rep sets. With Hundreds, you'll do 10 sets of 10 reps for one exercise per muscle group. Sounds the same as GVT, right? Not exactly.
Like protein, fiber slows the rate at which your body plows through carb calories so you feel full for longer and maintain steadier blood sugar levels, one reason why research consistently links fiber intake to weight loss. That means fibrous whole grain bread tends to be a better choice than white bread and also explains why fruits, which contain fiber and valuable vitamins in addition to sugar, beat straight-up candy every time.
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.
