Stretching in the gym

Hi everyone, I'm just here today with a quick blog on stretching in the gym and how useful it is in terms of creating good posture and fixing mobility issues and pain in the lower back. First off, there are two types of stretching techniques known mainly as STATIC stretching and DYNAMIC stretching. The difference is that static, meaning constant, is where you hold the stretch for an allocated time. Now if you're doing STATIC stretching, it's recommended to do so at the end of your training to stretch the muscle because when you train you can end up shortening the muscle from repetitive use. I would say if you want to increase flexibility, stretch the muscle for at least 45 seconds to about a 1 minute 30 seconds regularly to see flexibility improvements.
DYNAMIC stretching is where you you do your motions, whether its leg swings, arm swings, trunk rotations or your alternating windmills, this helps loosen up the muscles at the joints and activates the muscles and tendons around the supporting joints. This is really good to do at the start of the session so that you can go into your workout warmed up and ready to go.
Anyways, I hope some of this helped you guys and so if you enjoyed reading this, spread it around and help out other people who may be new to the gym. A little knowledge goes a long way.
