The best exercise to lose belly fat is high-intensity interval training (HIIT), followed by combined aerobic and resistance training, aerobic exercise alone, and resistance training, according to multiple large network meta-analyses of randomized trials. The most important truth, though, is that you cannot spot-reduce belly fat with crunches; fat comes off your whole body, including your midsection, when you train effectively and manage calories. This guide ranks the options by the evidence and shows you how to dose them.
What follows is the science-backed ranking, the details of each exercise type, practical dosing, and honest caveats about what does and does not work. This is general educational information, not personalized advice, and results vary from person to person.

A 2026 network meta-analysis of 61 randomized trials ranked the main exercise types for reducing visceral (deep belly) fat. An earlier 84-trial analysis reached the same broad conclusion, with vigorous aerobic exercise and HIIT most likely to be the best options for visceral fat, weight, total body fat, BMI, and waist circumference. The ranking is below.
| Rank | Exercise type | Effectiveness for belly fat | Notes |
| 1 | High-intensity interval training (HIIT) | Most effective | Works at a lower time commitment |
| 2 | Combined aerobic + resistance | Second most effective | Also best for subcutaneous fat and muscle |
| 3 | Aerobic alone | Comparable to combined | Needs a higher weekly dose |
| 4 | Resistance training alone | Least effective for belly fat | Best for preserving muscle |
The standout finding is that HIIT achieves significant belly-fat reduction at a relatively low dose (around 400 METs-minutes a week), while aerobic exercise alone needs roughly 1,100 METs-minutes a week to match it. In plain terms, HIIT delivers more belly-fat reduction for less total time, which makes it especially appealing if a busy schedule is your main barrier to exercising.
HIIT alternates short, hard bursts of effort with brief recovery, and it has the strongest evidence for belly fat loss. Running-based HIIT appears more effective than cycling for reducing visceral fat, while cycling may do slightly more for the subcutaneous fat just under the skin. Intervals at or above about 90 percent of your peak effort seem to reach the threshold that maximizes visceral fat reduction.
Encouragingly, you do not need marathon sessions. Even low-volume HIIT, under 15 minutes of actual high-intensity work per session, produces visceral fat reductions comparable to high-volume HIIT and better than steady moderate cardio. Effective protocols typically run three sessions a week for at least 12 weeks, with work intervals under 60 seconds and recovery of 90 seconds or less. A simple version: after a warm-up, alternate 30 seconds hard with 60 to 90 seconds easy, repeated for 10 to 20 minutes.
Why is HIIT so effective for belly fat specifically? Researchers think the intense bursts drive a larger metabolic and hormonal response than steady-state cardio, increasing fat oxidation and energy expenditure both during and after the session. The bigger practical advantage, though, may be adherence: short, time-efficient workouts are easier to fit into a busy week than an hour of jogging, and consistency over 12 weeks or more is ultimately what produces results. If you are new to exercise, you can start with gentler intervals and build up the intensity as your fitness improves.
Moderate-to-vigorous aerobic exercise such as brisk walking, jogging, or cycling significantly reduces belly fat and carries a top-grade recommendation from the European Association for the Study of Obesity. The American Heart Association points out that exercise can shrink visceral fat even without weight loss, around 6 percent reduction with no change on the scale, and meeting 150 minutes a week of activity may be enough to see a benefit.
That said, intensity matters: vigorous aerobic exercise outperforms moderate intensity for belly fat. These are some of the best cardio exercises for weight loss because they are accessible, easy to scale, and sustainable, and they double as the most accessible best exercise to lose weight at home, since brisk walking, jogging in place, stair climbing, or following a cardio video need little or no equipment.

Combining aerobic and resistance training is the second most effective approach for belly fat and the best for reducing subcutaneous abdominal fat, with studies showing more than double the reduction of aerobic exercise alone. It also preserves lean mass during weight loss, which is a top-grade recommendation, so it is an excellent all-around choice.
Resistance training on its own reduces belly fat the least of the four modalities, and the effect may not be significant in women or people with very high body fat. But that does not make it optional. Its real value is preserving and building muscle while you lose fat, which protects your metabolism and long-term function. The ideal plan for most people blends cardio or HIIT with resistance work two to three times a week. This also answers a related question, exercise to reduce thigh fat: like belly fat, thigh fat responds to overall fat loss plus strength work for the legs, not to targeted toning alone.
Translating the research into a routine, the practical targets are straightforward:
Consistency over those weeks matters more than any single workout. Build the habit, progress gradually, and give it time. A realistic weekly template for many people is two HIIT or vigorous cardio sessions plus two short resistance sessions, which covers belly-fat reduction and muscle preservation without taking over your schedule.
A few honest points save a lot of wasted effort. Spot reduction is a myth: doing endless crunches or sit-ups will strengthen abdominal muscles but will not preferentially burn belly fat, because fat loss happens systemically across the whole body. Targeted ab gadgets and belts do not change this.
Two practical caveats matter too. Exercise works best alongside a calorie deficit, since combining nutrition changes with training produces greater fat loss than exercise alone. And because HIIT is demanding, a cardiovascular risk assessment is wise before starting, especially if you are sedentary or have health conditions. Talk to a healthcare provider before beginning an intense new exercise program.
What is the single best exercise to lose belly fat?
High-intensity interval training (HIIT) has the strongest evidence for reducing visceral belly fat, and it works at a lower time commitment than steady cardio. Combining it with resistance training and a calorie deficit is the most effective overall approach.
Do crunches and sit-ups burn belly fat?
No. You cannot spot-reduce fat. Ab exercises strengthen the underlying muscles but do not preferentially burn belly fat, which comes off as part of whole-body fat loss through effective training and diet.
What are the best cardio exercises for weight loss at home?
Brisk walking, jogging in place, stair climbing, jumping rope, and following a HIIT or cardio video are effective and need little equipment. Vigorous intensity works better than moderate for belly fat, so push the pace when you safely can.
Can I target thigh fat with specific exercises?
Not directly. Like belly fat, thigh fat decreases with overall fat loss rather than spot training. Strength work for the legs builds and tones muscle, but reducing the fat over it requires whole-body fat loss.
How long until I see results?
Most studies show measurable belly-fat changes after 12 to 16 weeks of consistent training. Pairing exercise with a calorie deficit speeds results, and individual responses vary.
