What should be the placement of the hands of the spotter when assisting a lifter during a back squat?

In a back squat, the ideal placement of the spotter's hands is on the outside of the ribcage, under the chest. This position allows the spotter to effectively assist the lifter by providing support without interfering with their movement pattern. By being positioned underneath the chest, the spotter can effectively help lift the barbell or provide stability if the lifter encounters difficulty. This placement also allows the spotter to quickly react to any imbalance or failure without obstructing the lifter’s range of motion or the movement of the squat.

The other placements, such as on top of the shoulders, could interfere with the lifter's stability and control of the barbell. Supporting the lifter at the waist may lead to an inadequate response to a lifting challenge. Similarly, placing hands on the elbows could restrict arm movement, which is crucial for maintaining proper form and balance during the squat. Such interference can increase the risk of injury to both the lifter and the spotter, making it essential to utilize the correct hand placement.
