Where should spotting assistance be provided during a barbell back squat?

In a barbell back squat, providing spotting assistance at the ribcage, just below the chest, is crucial for ensuring the safety and stability of the lifter. This positioning allows the spotter to effectively assist the lifter if they encounter difficulty, while also maintaining a strong grip without interfering with the lift.

Spotting at the ribcage offers control and leverage, enabling the spotter to help lift the barbell back to a safe position if needed. Additionally, this area is less likely to obstruct the movement of the barbell throughout the squat, allowing the lifter to maintain proper form and alignment.

Other locations, such as the shoulders or forearms, could interfere with the lift and lead to potential injury for both the lifter and spotter. Spotting at the thighs may not provide sufficient leverage or control, especially if the lifter generates a significant amount of force during the squat. Hence, the ribcage just below the chest is the ideal spot for effective and safe assistance.
