![]() ![]() ![]() HIIT is just one kind of cardio exercise. It’s calories in, calories out, for the most part.” “Try to limit your portions and limit your calories. There’s really no getting around it,” says Janet Lee, a doctor of Chinese medicine, yoga instructor and health journalist based in Kansas City, Missouri. If you’re not operating on a caloric deficit - burning more calories in your HIIT workouts than you’re consuming - you may not lose weight. What you do in the gym has to balance with what you do in the kitchen. “High-intensity interval training - think group or circuit training and moving from station to station with little to no downtime - can assist you in dropping the weight, as long as it’s combined with a low-calorie diet or nutrition plan,” he says. “People can continue to grow their muscle mass while shedding extra fat in hard-to-reach places like the lower abdomen and thighs,” Brown says.īut there’s a cap to what HIIT can do, says Thomas Roe, a fitness trainer and endurance athlete based in San Antonio, Texas. HIIT can then help burn more fat rather than muscle, which can occur with steady-state cardio. HIIT can also boost your resting metabolic rate, and you’ll burn calories for up to 24 hours after your workout, Brown says. ![]() HIIT also increases lung capacity and blood flow within the body.” “Most people can burn the same number of calories in a 20-minute HIIT workout than they can in performing constant cardio or strength training for 45 minutes. “HIIT is a great way to lose weight in less time,” Brown says. There are multiple pluses to the HIIT approach: effective workouts, weight loss and health benefits. And overall, most HIIT workouts are completed in 10 to 30 minutes, which is often less time than you need for a full cardio conditioning or strength training session. Rest periods in HIIT workouts often incorporate active rest, a type of light activity like walking or jogging, that lasts longer than the amount of time you’ve spent on the strenuous exercise element. “This type of training stresses your cardiovascular system in a good way, causing your heart rate to speed up and then slow, which ultimately gives you more bang for your buck.” Jude Medical Center in Fullerton, California. “For instance, going for a jog and doing 30-second sprints every three minutes is HIIT, as well as doing as many chest presses as possible with the highest weight possible for 60 seconds in between treadmill walks,” says Megan Wroe, a registered dietitian and wellness manager with Providence St. So, what does a full HIIT workout look like? “You feel like you’re getting more of a workout because you’re breathing heavier and your muscles are burning.” “People love that overall feeling of going to 90% to 100% of your max heart rate,” he explains. Many people really enjoy this super effort, says Joel Freeman, a fitness trainer and entrepreneur based in Los Angeles. To calculate your max heart rate, subtract your age from 220. Some super high-intensity HIIT workouts will take you right up to 90% or 100% of your max heart rate for a short time to really crank up the heat. You cross that high-intensity threshold –usually around 80% of maximum heart rate - when you’re almost out of breath or unable to hold a conversation, Brown says. More specifically, HIIT allows the body to achieve a higher heart rate for short periods of time.
