On HIIT 100s sets during Weeks 1-3, when rest periods are 30 seconds or more, perform the first three sets of 10 as fast and explosively as possible. This will help build more muscle power and strength, despite using such light weight. On Sets 4-6, keep the movement slow and controlled, focusing on the contraction and squeezing each rep at the top for one to two seconds. This helps establish a strong mind-muscle connection, which is critical for muscle size, shape, and separation.

Don't banish certain foods. Don't tell yourself you'll never again eat your absolutely favorite peanut butter chocolate ice cream. Making all treats forbidden is sure to make you want them even more. The key to long-term success is making healthy choices most of the time. If you want a piece of cake at a party, go for it! But munch on the carrots rather than the chips to balance it out.
We often make the wrong trade-offs. Many of us make the mistake of swapping fat for the empty calories of sugar and refined carbohydrates. Instead of eating whole-fat yoghurt, for example, we eat low- or no-fat versions that are packed with sugar to make up for the loss of taste. Or we swap our fatty breakfast bacon for a muffin or donut that causes rapid spikes in blood sugar.
Why does HIIT training work better than conventional cardio for fat loss? When you do cardio at the same pace, your body adjusts itself to the workload and tries to conserve calories. (After all, your body doesn't know how long or hard you plan to work out.) Interval training forces your body to burn more calories -- and tap into fat stores -- because it has no choice. Science says so: One study at Laval University found people who performed HIIT cardio lost nine times more fat than people who performed moderate cardio at a consistent speed.
Based on my experience in nutrition counseling, most of us tend to snack on foods that aren’t nutrient-dense, but are high in calories. For example, skipping sugary beverages is often the easiest way to lose weight faster. You don’t feel full from drinks — even the ones that do contain calories — so swapping those out for sparkling water or unsweetened tea and coffee is the best place to start. Other major culprits often come in refined grains like cereals, chips, crackers, and cookies.

Blood vessels (veh-suls): The system of flexible tubes—arteries, capillaries and veins—that carries blood through the body. Oxygen and nutrients are delivered by arteries to tiny, thin-walled capillaries that feed them to cells and pick up waste material, including carbon dioxide. Capillaries pass the waste to veins, which take the blood back to the heart and lungs, where carbon dioxide is let out through your breath as you exhale.


Even if you do meet your goal, it's nearly impossible to keep off the weight over the long term: "The amount of restriction required [to maintain that number] will make you so hungry that you’ll eat everything in sight—it’s survival instinct," Dr. Seltzer says. And since calorie restriction gradually slows your metabolism, your body will be less prepared to burn the foods you binge on, he adds. That could mean gaining more pounds than you lost in the first place.
It’s natural for anyone trying to lose weight to want to lose it very quickly. But evidence shows that people who lose weight gradually and steadily (about 1 to 2 pounds per week) are more successful at keeping weight off. Healthy weight loss isn’t just about a “diet” or “program”. It’s about an ongoing lifestyle that includes long-term changes in daily eating and exercise habits.
I started at 245lbs, I began my journey in 2015 I am currently 170lbs at 5'10. I never ever thought I would be addicted to working out, I love it! I started simply by doing morning and evening walks for a year then I wanted more so I did a lot of research and came across so many trainers but Jillian caught my attention. I've never felt better in my life. I'm a mom of three beautiful boys who by the way do JM with my youngest being only 5 years old! Thank you Jillian! You have helped me so much!
Count calories and macros. You’ll need to track calories and macros (grams of fats, protein and carbs) religiously, at least for the first month. First, use this calculator to determine your body fat percentage- and don’t suck in your gut when you measure your waist. Then, use this calorie calculator (be sure to select the lean mass formula) to determine your Total Daily Energy Expenditure.
"Only doing abdominal-focused workouts, like crunches, won’t help you banish the bulge. Belly fat is simply where your body stores energy, so you need to take a whole-body approach to tackle it. HIIT training (high intensity interval training) is a great way to burn fat and get your heart rate up. Squats, burpees and treadmill sprints are all examples to try."
