Swimming
Swimming is a sport that mobilizes almost all muscle groups, especially the abdominal, back and hip muscles. According to Dr. Edward Laskowski, a sports medicine expert at Mayo Clinic (USA), swimming helps increase stable heart rate, burn calories effectively without putting pressure on joints, suitable for many ages.
Swimming styles such as cross-country swimming, butterfly swimming or frog swimming all require tightening abdominal muscles to maintain balance and create push-ups, thereby helping the waist area to be noticeably firm if maintained regularly 3-4 times a week.
Cycling
Cycling, especially outdoor cycling or high-intensity bicycles, is considered an effective "weapon" to reduce belly fat. According to the American Heart Association (AHA), cycling for 45-60 minutes can consume 400-600 kcal, while strongly activating the thigh muscle group, buttocks and core muscles.
British fitness expert James Smith said that maintaining a stable position when cycling forces abdominal muscles to work continuously, helping to reduce visceral fat - the most dangerous type of fat accumulated in the abdomen.
Boxing
Boxing is not only a martial art but also a cardio exercise - combined strength. Continuous punching, dodging, and spinning movements make abdominal muscles, intercostal muscles, and shoulders work hard. According to boxing coach and fitness expert Ross Enamait (USA), boxing can burn up to 700-800 kcal per hour, and at the same time help the body become firmer faster than many conventional forms of exercise.
Experts note that to achieve clear abdominal reduction effects, it is necessary to combine regular exercise with a reasonable diet and enough sleep, instead of just relying on one sport.
