3 HIIT Workouts For Weight and Fat Loss

Exercise alone might not be enough for most people to lose weight, but research shows that those who work out tend to lose and maintain more weight than those who don’t.

That doesn’t mean you have to spend hours at the gym every day. HIIT (High-Intensity Interval Training) is a great way to burn calories and boost fat loss in a short amount of time. HIIT involves short bursts of intense activity followed by low-intensity periods or rest, with workouts usually lasting 10-30 minutes.

Joey Hogger, a Personal Trainer and Assistant Gym Manager at PureGym in London, explains why incorporating HIIT into your routine can help with weight loss and shares three fat-burning HIIT workouts you can try.

Before jumping into the benefits of HIIT for fat loss, it’s important to remember that weight loss happens when you’re in a calorie deficit. This means consuming fewer calories than you burn, whether through daily activities, exercise, or NEAT (non-exercise activity thermogenesis). The most effective way to achieve a calorie deficit is through diet. You can learn more about calories and weight loss here.

HIIT For Weight Loss: How Does It Help?

Whether you’re aiming to improve fitness, lift your mood, or shed fat, HIIT is an awesome workout choice—you can check out all the great benefits of HIIT training here.

3 HIIT Workouts For Weight and Fat Loss

I often recommend HIIT to clients who want to lose fat, and there are two big reasons why it’s so effective.

First, HIIT burns a lot of calories while helping you maintain muscle. A 20-minute HIIT session can burn as many calories as a 40- or 60-minute cardio workout, but the benefits don’t stop there! By pushing your body to its max in short bursts, your body taps into the anaerobic system for energy (since oxygen isn’t available). After the workout, your body needs extra oxygen to recover—this process, called excess post-exercise oxygen consumption (EPOC), can keep burning calories for up to 24 hours!

The second reason is psychological. Let’s face it—traditional cardio can be super boring, which makes it harder to stay motivated and consistent. The more workouts you skip, the further you get from your fat loss goals. HIIT, on the other hand, is intense but short—just 10-20 minutes—and you can do it at home with no equipment. Plus, it’s way more fun than steady cardio. Who doesn’t love jumping around to their favorite playlist?

Does HIIT Burn Stomach Fat?

People come in all shapes and sizes, and where your body stores (and loses) fat mostly comes down to genetics. Some people lose weight from their stomachs first, while others might lose it from their legs or arms. Sadly, you can’t pick where the fat comes off first!

Studies show that HIIT can help reduce belly fat, but that’s usually because of overall weight loss. If you’re looking to lose fat from your stomach, the best approach is to maintain a calorie deficit and stick to regular exercise, including HIIT workouts.

How Much HIIT Is Too Much?

By now, you’re probably convinced that HIIT is great for fat loss. But before you jump into doing a HIIT workout every day, it’s important to know that rest is just as crucial. Like all workouts, rest days give your body and nervous system time to recover and help prevent injuries. HIIT is intense, so it’s best to stick to 2-3 sessions per week. Doing too much can raise cortisol levels (the stress hormone), which, if elevated for too long, can actually cause weight gain and other health issues.

You should also aim to strength train at least twice a week. Strength training helps preserve and build muscle as you lose fat, which boosts overall health and improves metabolism.

Here’s an example of a balanced workout week:

  • Monday: 40-minute full-body strength training, 8,000 steps
  • Tuesday: 20-minute HIIT workout, 8,000 steps
  • Wednesday: Rest
  • Thursday: 40-minute full-body strength training, 8,000 steps
  • Friday: 15-minute HIIT workout, 8,000 steps
  • Saturday: 30 minutes of stretching
  • Sunday: Rest

Fat burning HIIT Workouts

If you’re ready to add HIIT to your weight loss routine, here are some great workouts to try.

Before starting, take 2-5 minutes to warm up. This could be a quick walk, jog, or simple bodyweight moves like high knees, jumping jacks, or squats with forward folds. After your workout, spend a few minutes cooling down with stretches to lower your heart rate. You can check out some warm-up ideas here and find stretching exercises here.
