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.
A good squat is a deep squat performed correctly. Inadequate ankle and hip mobility often keep lifters from squatting well. How you prepare to squat will determine how deep you can go. Do mobility exercises for the ankles, knees, and hips, then do stability exercises for the core before squatting. Use box squats to perfect your form. Front squats are a good option for those unable to back squat.
