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.
How low you go when you squat determines which muscles you'll target. Deep squats, in which your hips descend below your knees, focus on the glutes. Squatting to 90 degrees targets the quadriceps more. Because the hamstrings play a stabilizing role, squat depth doesn't affect them.
