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.
Legs. Pushing your body up and down during a squat activates many of the muscles in your upper and lower legs. Your quadriceps and hamstrings are two primary muscles worked during squats. You'll likely feel those muscles working as you squat up and down. Including squats in your strength training routine helps tone and define the muscles in your thighs and calves.
