Exercise time should be kept for more than 20 minutes, and after 20 minutes, the proportion of fat energy supply begins to increase, occupying the main energy supply position. It can consume 300 kcal of exercise time (about 100 kcal for running or walking every 1500m): jogging for 4500m (4.5km) for 30-50 minutes, cycling for 60-75 minutes, walking for 60-90 minutes, swimming for 30-40 minutes and playing tennis for 40 minutes.

First, swimming. The data shows that the thermal conductivity of water is 26 times that of air. If heat dissipation in water at the same temperature is more than 20 times faster than in air, it will effectively consume people's heat. The test shows that swimming in water 100 meters consumes heat energy 100 calories, which is equivalent to running 400 meters on land, riding a bike 1000 meters, or skating 1500 meters.

Second, climb the mountain. The effect of climbing mountains to lose weight in summer is remarkable. Climbing a mountain in hot weather will increase physical exertion by about 20%-30%. The best way to lose weight is aerobic exercise, and mountain climbing is the best aerobic exercise. Every time you climb a mountain to get ready for a rest, take a watch and measure it: the heartbeat is 120 per minute, which can last for 10 minutes, indicating that exercise has achieved the purpose of burning fat.
