This is easy to understand, because you don't warm up and go to work directly, and your body hasn't moved yet. As soon as I get up, I exercise vigorously, and my body is not ready, so I can't adapt at all, so I am very fragile. For bodybuilders, once injured, it hurts for several days, and when it is serious, it will cause habitual injury and make people miserable.

2. Warm-up exercises can relieve muscle soreness.

No matter how much exercise you do next, even if it's just running, it's best to warm up before exercise. When doing warm-up activities, joint stretching should be done first, which can relax muscles and make blood flow smoothly, otherwise muscle soreness will easily occur after exercise.

3. Warm-up exercise can play a buffering role

After a day's work, all my muscles are stiff. If you don't do some warm-up activities before exercise, especially if you suddenly do a lot of exercise, it is particularly easy to cause acute joint injuries such as lumbar joint sprain. The process of warm-up is to play a buffering role in the static state and sports state, so that the limbs can adapt in advance and avoid injury.

4. Warm-up exercise can increase muscle metabolism.

Before the start of exercise and fitness, warm-up exercise with a certain intensity can strengthen the metabolic process of muscles, increase the temperature of muscles, reduce the viscosity of muscles, increase the extensibility and elasticity of muscles and ligaments, and reduce sports injuries caused by severe contraction of muscles.

It can also improve the ability to excrete metabolic waste, because blood flows faster and waste is discharged faster, so we are not easy to get tired during real training.
