How to properly stretch to maintain health

stretching is one of the best exercises to do on a daily basis, but it must be done properly.
As a massage therapist I specialize in safe stretching, and proper technique. some stretching can be done by yourself, while others can only be done with the help of a licensed professional.
what ever type of stretching the intention should be to lengthen the muscle as much as possible. Benefits are that it increases flexibility.
It also helps muscles relax and return to their normal length. there are many different types of stretching.
1. ballistic stretching- this is when there is a bouncing action at the end of the stretch. This is not recommended because of the damage it can do to the muscle.
2. Active stretching- This is when a person simply stretches by them self.
3. Passive stretching- is when you are stretched by the therapist.
4.proprioceptive neuromuscular facilitation or PNF- this is a technique where the patient and therapist work together, it is described by an isometric contraction followed by a post isometric stretch. this can only be done by a licensed professional
