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 primarily target your thighs and derriere, but they also tone your hamstrings and calves. Your back muscles and abs work to steady your spine during the movement, making squats a core strengthener. Even your breathing muscles get a workout when you're squatting. Squats are a great all-around thigh toner.
