Besides being extremely relaxing, research has demonstrated the positive effect on preventing muscular injuries and also in injury treatment. Stretching helps promote blood circulation to the muscles, ‘warming’ them up for exercise so that they are not too stiff.
Stretching should always be relaxing with your breathing slow, rhythmical and under control. Do not hold your breath while stretching. If a stretch position inhibits your natural breathing pattern, then you are obviously not relaxed. Just ease up on the stretch so you can breathe naturally.
Depending on the reason for stretching you should never rush stretching exercises as they are important in preparing your body for exercises and improving flexibility.
If you do not stretch properly there is a greater chance of experiencing tight and sore muscles, and even a muscular injury. Always make sure when stretching that you allow at least 30 seconds for each stretching exercise.
