At the beginning of exercise, the running speed should be limited to no uncomfortable feeling, and the running distance should be no uncomfortable feeling. Muscle pain in lower limbs may occur after running, which is a normal reaction. Insisting on exercise will disappear after a few days.
In order to determine the level of their own sports, after running for three to four months, take 12 minutes as the starting point to calculate the level.
30 ~ 39 years old, the running distance of 12 minutes is less than 1.5 ~ 1.8 kilometers, which indicates that the sports level is poor; If it can reach 1.8-2.6 km, it means that the sports level is good; If it's more than 2.6 kilometers, it's good exercise.
Hope to adopt!
