Information is always changing. 10 years ago the general consensus was that fascia didn't contract. Muscles contract, fascia was just the "bag" it's in. Now we know that fascia does indeed contract. Now there are some people that describe the anatomy of a person as a bag of fascia with 600 or so compartments for the muscles.
It has been said that the fascia contributes up to 30% of the contractile force. If the fascia is not healthy, it is tight or weak, the true expression of strength will never be realized. The true expression of effortless movement will never be realized.
Do your foam rolling, do your multi planar movements, drink your water, keep your fascia healthy. You will be rewarded with improved strength and better movement. Test it out. Create a marker workout. Record time or weight or both. Next time through, do some aggressive foam rolling work with a roller, lacrosse ball ect. before, between and after and compare the marker workout. I think you will be pleasantly surprised.
