Squats are a full body exercise that train 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 tendonsthroughout the lower body.
Squats are considered a vital exercise for increasing the strength and size of the legs and buttocks, as well as developing core strength. Isometrically, the lower back, the upper back, the abdominals, the trunk muscles, the costal muscles, and theshoulders and arms are all essential to the exercise and thus are trained when squatting with the proper form.
On October 8, 2011, Jonas Rantanen of Finland performed a squat with a weight of 575 kg (1268 lb), beating the previous record by Donnie Thompson (USA) of 573 kg (1265 lb).
