Why do two people with the same height and weight have different body shapes?
The reason why two people with the same height and weight have different body shapes is that their body fat percentage and muscle content are different. Weight is made up of many factors, besides fat and muscle, it also includes bones and blood. Muscle accounts for about 40% of body weight, but adipose tissue accounts for a large proportion of obese people.
The same amount of muscle and fat, the molecular volume of fat is about 3 times that of muscle. It can be seen that two people who are also 120 kg have a large proportion of muscle tissue and look thinner; People with a large proportion of adipose tissue look fatter.
In short, obesity can't be judged by weight. It is scientific to see your body fat content.
Which of several common fitness exercises has the best fat burning effect?
1, jump rope
Skipping rope is a high-intensity fat-burning exercise, which can not only increase the heart rate in a short time, but also exercise the whole body muscles and delay the muscle loss. Skipping rope/kloc-burning fat in 0/5 minutes is equivalent to jogging for 30 minutes. Skipping rope can improve basal metabolic rate and burn calories continuously. However, people with high body mass index, bone and joint diseases, high blood pressure and diabetes can't jump rope to avoid accidents.
Step 2 jog
Jogging is a simple aerobic exercise, which can be carried out anytime and anywhere, and will not be affected by venues and equipment. If you keep jogging for 60 minutes, you will consume 550 kilocalories. In order to improve the speed of burning fat, we might as well take intermittent jogging, that is, a combination of brisk walking and jogging. However, it is necessary to master the correct jogging posture, hold your head high, tighten your abdomen, and cooperate with abdominal breathing, so that your arms can swing freely with your body.
Step 3 swim
Swimming is a sport suitable for summer. General swimming 1 hour consumes 650~900 kilocalories. Because of the buoyancy of water, swimming can reduce joint pressure and is suitable for obese people with large base. For your own safety, you should choose a regular swimming pool; Wash your body with running water after swimming.
Step 4 play table tennis
Playing table tennis for one hour in a row consumes 350~400 kilocalories. Table tennis is a low-intensity sport, which is more suitable for middle-aged and elderly people. Not only make the limbs more coordinated, improve the flexibility of the body, but also help to lose weight.

skill
Obese people can choose suitable exercise according to their own situation, and ensure that they can do moderate-intensity aerobic exercise for more than 30 minutes every day, 4-5 times a week, and their heart rate reaches 140~ 150 times per minute during exercise.
In addition to aerobic exercise, strength training, such as sit-ups, push-ups or squats with bare hands, lifting dumbbells, etc. , can promote muscle synthesis, increase the proportion of muscle tissue, improve the basal metabolic rate, lose weight over time, and help shape up.
