Squat (exercise)

The squat is a lower body exercise used in strength training. It is also a competitive lift in powerlifting and an essential movement in the sport of weightlifting. The exercise's main emphasis is on the quadriceps and the glutes, but it also involves the hamstrings, the calves, and the lower back. The squat is often called "the King of exercises" because it is capable of inducing more and faster muscle growth than any other exercise.

Movement

The squat is performed by bending the legs at the knees and hips, lowering the torso between the legs, and then reversing direction to stand up straight again. The torso remains relatively upright throughout the movement. It acts as a supporting structure, unlike its role in the deadlift. Proper technique is critical, otherwise serious injuries or gradual injury over a period of time can occur. The back must be kept straight and never rounded, otherwise excess strain can be placed on the spine and cause serious injury. Lifting belts can be used to help support the lower back.

Safety

The feet should be flat on the floor, with even distribution of weight between the heel and the ball of the foot during eccentric muscle action. In order to reach a range of motion beyond parallel, individuals without sufficient ankle flexibility may try putting a flat board beneath the heels to artificially improve their flexibility. Similarly, a wedge shaped board may be used, allowing the entire foot to remain in contact with a single surface, improving stability over the first technique. Both methods are short-term fixes and require that regular stretching and a full range of motion be employed to maintain and increase flexibility to the desired levels with the ultimate aim that the board's use be eliminated. In the sport of weightlifting, a specifically designed squat shoe that has a heel elevated by an encased wooden block is commonly worn. Some experts discourage the use of a board or heel, however, because it may lead to a breakdown of proper form. In any squat, even one performed without these depth-increasing aids, the lifter should take care to exert force from the heel of the foot and not from the toes during concentric muscle contraction in order to maintain balance and keep the focus on the muscles of the thigh.

To avoid the chance of getting stuck under the bar, heavy barbell squats are best performed either inside a power cage or in the presence of one or more spotters, who can help to safely return the barbell to the squat rack at the end of the set if the lifter is unable to do so.

Individuals who find that they cannot safely perform the squat are advised to try the leg press. For those who do not know how to squat, it is highly recommended that one learns directly from a qualified professional - squatting without proper technique can lead to very serious long-term injuries. Furthermore, one should consult one's physician before undertaking a rigorous exercise such as the squat.

World record

The world record for the assisted squat is 1220 lb (553.4 kg), performed by Mike Miller. However he did not fully complete the lift. . Miller later requested this squat be stricken from the record books as he himself knew it was not of the correct depth. The APF did not do this however. It is widely accepted that Andy Bolton now holds the all time squat record with a lift of 1213lbs.

Variants

The squat has a number of variants, some of which can be combined (e.g. a dumbbell split squat):

• In the back squat, a barbell is held across the upper back.
• In the hack squat, a barbell is held just behind the legs.
• In the sissy squat, a dumbbell is held behind the legs while the heels are lifted off the ground and the torso remains flat while the lifter leans backwards. Sometimes this is done with a plate held on the chest and one arm holding onto a chair or beam for support.
• In the overhead squat, a barbell is held overhead at full extension in a wide-arm snatch grip.
• In the front squat, the weight (usually a barbell) is held on the front of the shoulders with the arms crossed and hands placed either on top of the barbell or holding the barbell with a clean grip.
• In the Zercher Squat, the weight is held in the crook of the arms.
• In the dumbbell squat, the weight may be held hanging from the side (suitcase position), vertically at the chest (goblet position), or above the head with the arms extended (waiter position).
• In the dumbbell front squat, the weights are held resting on the shoulders.
• In the box squat, the lifter sits back onto a short box, momentarily relaxing the hip flexors, before contracting them and rising off of the box. The use of a box sets a consistent depth and emphasizes the posterior chain over the muscles of the quadriceps.
• The pistol squat, a freestanding one-legged squat where the non-lifting leg is held in free space.
• The split squat, an assisted one-legged squat where the non-lifting leg is placed, at the ankle, on a knee-high platform behind the lifter.
• The hindu squat is a squat done without weight where the heels are raised and the weight is placed on the toes. The knees track far past the toes. This is a controversial exercise, and it criticized for being damaging, evidencing the knee problems historically experienced by Indian wrestlers who did hundreds daily.
• The jump squat, a plyometric exercise where the squatter jumps off of the floor at the top of the lift.
• The air squat is a squat done with no weight or barbell, often at higher repetitions than other variants
• The sumo squat is done with the legs further apart than usual

The squat also has a number of commonly specified depths:

• The quarter squat descends about half of the way down towards a half squat.
• The hams-parallel squat descends until the bottom of the thighs, the hamstrings, reach an imaginary line drawn parallel to the floor.
• The quads-parallel or powerlifting legal squat descends until the crease of the top of the thighs and hips are at the same level as the knees.
• The half squat descends to a depth that is between hams-parallel and quads-parallel.
• The full or ass to the grass (ATG) squat descends past quads-parallel to the maximum that a lifter's flexibility allows.

Squatting below parallel qualifies a squat as deep while squatting above it qualifies as shallow.
