▎ jogging will make your legs thinner

.

People’s muscle fibers are divided into two categories: white muscle fibers and red muscle fibers

.

White muscle fiber, also known as fast muscle fiber, main explosive force, general anaerobic exercise will make white muscle fiber become developed

.

Its appearance is stout, so you will find that sprinters, football players who need a foot in front of the door, weightlifters and so on, their legs are generally very stout

.

Red muscle fiber, also known as slow muscle fiber, is mainly used for endurance

.

Generally speaking, the red muscle fibers of aerobic joggers are especially developed

.

Its shape is thin and long, so if you pay attention to the observation, you will find that the long-distance runners’ legs are very slender

The red muscle fiber is relatively developed, so the legs will be very slender

▎ after running, I feel that my legs are getting thicker, which may be due to the lack of stretching

.

However, some people often complain that I want to lose weight in running, but I didn’t expect that my legs are getting thicker and thicker, which may be due to the lack of stretching after running

.

🤨 After a certain amount of running, the muscles contract

.

If you don’t stretch in time, the muscles can’t stretch, shrink into a ball, and pile up together for a long time, it may cause the calf to be thick

.

But this does not mean that the legs are really thicker

.

Timely relaxation and stretching can relieve muscle tension, fully stretch the contracted muscles, and promote the faster elimination of lactic acid

.

Not only can make the leg become more slender, but also can relieve muscle soreness

.

So for your beautiful legs, you must stretch after running! This is the 15th issue of “ask if you don’t know” column
