When most people think of HIIT they think of it as applicable only for cardio, yet it can also be used in weight training. After all, weight training itself is a form of HIIT—you do a set with all-out effort, rest, then do another set, rest, and repeat. Resting two to three minutes between sets, however, is too long for a training session to be considered an effective form of HIIT. But all you have to do is shorten rest periods and you're doing a kind of HIIT that burns fat.
Call it what you will: An eating plan, a lifestyle, a diet, a philosophy, but few things garner such heated debate as how to lose weight. The truth is, whether you’re on a low-carb keto program, devoted to the Paleo lifestyle, all in to the Whole 30 or remain committed to low-fat eating, these plans have more in common than you think. What’s more, follow any one of them religiously, and you’ll likely notice results.
The following workouts are simple to follow, just not very easy to do. For each major muscle group, after following the HIIT 100s protocol on your first exercise, you'll do three more sets to failure of the same exercise using your 10-rep max (10RM). Of course, after doing 10 sets of 10 reps, you'll no longer be able to complete 10 full reps with your 10RM weight—probably more like 5-7 reps. On the third set, you'll do a dropset with the same weight you used for HIIT 100s (50% of your 10RM) and do as many reps as possible.
If you want to lose weight you should start by avoiding sugar and starch (like bread, pasta and potatoes). This is an old idea: For 150 years or more there have been a huge number of weight-loss diets based on eating fewer carbs. What’s new is that dozens of modern scientific studies have proven that, yes, low carb is the most effective way to lose weight.
That’s because strength training helps you build muscle, which will replace body fat. In fact, strength training is one of the few activities you can do to spike the amount of calories you burn, even after you’re done with your workout. Bonus: When your metabolic rate becomes faster due to muscle growth, you’ll have a little more wiggle room in your diet if that’s something you struggle with, says Dr. Cheskin.
Not all fat is bad. Healthy or “good” fats can actually help to control your weight, as well as manage your moods and fight fatigue. Unsaturated fats found in avocados, nuts, seeds, soy milk, tofu, and fatty fish can help fill you up, while adding a little tasty olive oil to a plate of vegetables, for example, can make it easier to eat healthy food and improve the overall quality of your diet.
