All take part in the fitness runners, often should pay attention to adhere to and step by step, special attention should be paid to control the amount of exercise. In addition, must learn to ＂self control＂, which is particularly important. Because sometimes the desire of the running will suddenly disappeared, it needs to be ＂can't run＂ or ＂don't want to run＂ distinction. , of course, if you don't run when sick, while in other cases should overcome the ＂inert＂, insist to take exercise.

At the beginning of the exercise, running speed limit by no uncomfortable feeling, run the distance with no hard feelings advisable. Running after lower limb muscle pain may occur, this is a normal reaction, insist to take exercise this kind of phenomenon will disappear in a few days.

To determine the level of their exercise level, to participate in the running for three to four months after some tests, test runs the distance in 12 minutes for calculating level starting point.

30到39岁的年龄断， 12 minutes to run the distance of less than 1.5 to 1.8 kilometers, explain exercise level is poor; If can reach 1.8到2.6千米， specify exercise level is good; If more than 2.6 km, is good exercise.
