Although running can also increase some muscles, running consumes more fat, which means losing weight is better. Many bodybuilders would rather train for three hours than run because running will consume some muscles. As a professional long-distance runner, he began to turn to strength training. After training, because they have a certain sports foundation, and their physical strength and endurance are much stronger than ordinary people, their muscle training efficiency is better.

Two. Changes in muscle circumference

After long-distance runners change to strength training, the biggest change is definitely the change of muscle circumference. In our impression, like long-distance runners, they are slimming, mainly because of long-term running. When they started strength training, their muscles began to grow steadily and their diet was reasonable. Their weight and muscle content will gradually increase, and their muscle circumference will be much stronger than that of long-distance runners.

Third, physical changes.

It's not that the physical quality of long-distance runners is not as good as that of people with healthy muscles, but that even if we ordinary people don't pay attention to long-distance running, we will suffer some physical injuries, not to mention the amazing running amount of long-distance runners. There are also some results of long-term running, such as knees and feet. Ankle injury is definitely more serious for us ordinary people than running. Although running can really improve our physical fitness, it is the same in the case of quantitative weightlifting. Everything must have a certain degree to find the best balance.

Fourth, changes in muscle performance.

Many of us are actually curious about why long-distance runners look so thin but run so fast, mainly because their muscle training methods are different. The muscles of long-distance runners belong to endurance muscles, so their muscles have better endurance and flexibility, but their strength will be less than one. When some people start strength training, muscle strength begins to rise steadily, especially in the legs.
