Barbell squats are one of the three lifts in powerlifting. Questions are about effective technique, variations, and programs for squatting with or without resistance.

In strength training, the squat is a compound, full body exercise that trains primarily the muscles of the thighs, hips and buttocks, quads (vastus lateralus medialis and intermedius), hamstrings, as well as strengthening the bones, ligaments and insertion of the tendons throughout the lower body.
