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.
Squats are among the handful of essential strength-building and strength-maintenance exercises. They also happen to be highly-functional and, done properly, they can engage about 200 different muscles.
People tend to want to do barbell squats because they are the most demanding and stressful, but for beginners and for those who just want to stay fit and mobile without really increasing strength, higher-rep body-weight squats or light-weight squats (eg four sets of 20+ per week) are good exercise. You have to get low for it to work.
