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.
Squats are possibly the most fundamental exercise. They are one of the best leg exercises because they work a good percentage of your muscle mass. Proper back squats will help you get stronger, gain muscle, burn fat and tone your entire body more than any other exercise.
