We see these foam rollers used wherever exercise is undertaken, with those using them swearing by them, confidently pronouncing that their muscles are more relaxed after using the roller after exercise.

Tom Myers wrote a fascinating piece on foam rollers and it is certainly worth a read.
What is happening inside when you do foam rolling or use any types of balls or tools for self-myofascial release (SMR)?

Like squeezing a sponge over the sink and then letting it fill again while doing the pots and pans, this is generally a good idea. As the old bedouin proverb has it: “Water still: poison!
