How does foam rolling work?

In: 11

You take a hard piece of foam and you roll around on it.

You body weight will press down the muscle against the foam roller and this performs a similar action or a massage.

We don’t exactly know for sure, but the most popular theory involves myofascial release.

Essentially, your muscle is made up of individual fibers. The fascia is like a sausage casing made of a bunch of strands that cover each individual fiber and the muscle itself. Those strands can get tangled up and stuck together. This leads to those knots in your muscles (formally called myofascial trigger points) you love so much. The slow pressure from a foam roller (and you should be using a foam roller very slowly), can help loosen up those knots.
