Kashrut: Jewish Dietary Laws. Kashrut is the body of Jewish law dealing with what foods we can and cannot eat and how those foods must be prepared and eaten. Kashrut comes from the Hebrew root Kaf-Shin-Reish, meaning fit, proper or correct.
Squats obviously help to build your leg muscles (including your quadriceps, hamstrings, and calves), but they also create an anabolic environment, which promotes body-wide muscle building.
Factor #1: Larger Muscles Require More Recovery Time. Just compare how you feel after several sets of heavy squats compared to a bicep curl workout. Weightlifters do not train the squat with the same intensity as powerlifters, so they can squat almost every workout. Powerlifters train at much higher intensities to the extent that many only have to squat once a week and some even once every ten days. High-intensity squats need lots of recovery.
