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.
When you squat, your entire upper body is working to stabilize the weight. The muscles of the chest, shoulders, arms, back and abs all work in the movement. While squatting won't give you huge arms, it is a great exercise that develops strength, stability and endurance while working the cardiovascular system as well.
