Flexibility for better results from your workouts.
Post-exercise stretching has been performed as a recovery modality for many decades, if not centuries and beyond, and the current body of research demonstrates that it may have several beneficial effects on recovery. These effects range from decreasing muscle soreness, albeit by a very small amount, increasing flexibility, increasing local blood flow, and decreasing neural excitability. As a result, static stretching may be a useful form of recovery following exercise.
Assisted stretching works with Proprioceptive Neuromuscular Facilitation (PNF) which is a more advanced form of flexibility training that involves both the stretching and contraction of the muscle group being targeted. PNF stretching was originally developed as a form of rehabilitation, and to that effect it is very effective. It is also excellent for targeting specific muscle groups, and as well as increasing flexibility, it also improves muscular strength. To get the most out of your workout and exercise program you need to spend some time working on flexibility.
