Explanation:

Muscle flexibility is an important factor for both performing functional activities and achieving good athletic performance. It can be defined by the muscle's ability to stretch, allowing one or two joints in series to increase its range of motion. Of course, this flexibility is not achieved without any effort and it is necessary that specific exercises are done so that the flexibility is stimulated in a certain part of the body.

The exercises that have shown positive results in terms of stimulating flexibility are stretching and flexing, so we can say that if someone wants to improve the flexibility of the chest and side muscles, the ideal would be for them to do side stretch and chest and arm bends
