We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
It has become common for people to foam-roll their muscles before weights or calisthenics nowadays. Generally-speaking, before their warm-ups and stretches. It's a brief massage, "myofascial release" as it is termed but that sounds dubious to me. Sometimes it hurts, but in a good way. Sometimes people do it after a workout.
I have no idea whether it does any good, but I do it anyway: back, butt, quads, hammies, sides of upper legs, and calves. I don't do my arms. Takes less than 5 minutes, feels good.
Amazon sells them but all gyms have stacks of them.
