Stretching is an important part of a workout. It allows your muscles to relax, release tension, and improves blood flow. In this way, it helps to recover from injuries and get back to the normal state. Stretching is not just a matter of changing the position of your body, but it also requires you to change the shape of your body, so you can get rid of any pain.

Warm-up and Stretching Exercises:

A warm-up exercise is a simple and effective way to reduce the risk of injuries and improve your performance. It should be done immediately after the workout, before you start to cool down. The warm-up exercise allows you to improve your mobility, increase the flexibility of your muscles, and reduce the risk of injuries. It also improves the blood flow to the muscles, which is important for the recovery of muscle injuries.

Warm-up and stretching exercises can be done in several different ways. There is a general rule of thumb, which is that you should do your warm-up exercise for at least 45 seconds. You should try to make each warm-up exercise as comfortable as possible.
