For example, 1 hour aerobic exercise, the warm-up time should be within the range of 6- 12 minutes. At the same time, according to the age, competition or non-competition, sports, personal physical differences, seasons and temperatures, the time required for warm-up exercise will be different.

The length of warm-up is very important. Because the time is too short, the body can't warm up fully. If the preheating time is too long, it is not necessary. On the contrary, it will waste precious physical strength and affect the enthusiasm and enthusiasm of fitness.

So we need a certain warm-up time, about 10 minutes. During this time, you need to warm up fully and do every movement well.

Warm-up needs attention:

When we warm up, we need to focus on our knees and do enough warm-up exercises about them. Because the knee is a very fragile part for runners. The impact of our running often gives the knee, which is a fragile part. So many runners have knee health problems.

If you want to protect your knees, you must warm up your knees and let them secrete synovial fluid as much as possible, which can also offset some shocks for you and is also a way to protect your knees.
