What is buttwink?

Buttwink is a term used in weightlifting and squatting to describe a phenomenon where the pelvis tucks under at the bottom of a squat, causing the lower back to round or flex. This can also be referred to as a posterior pelvic tilt.

The term "buttwink" is often used as a way to describe the movement as it creates a visible rounding or tucking in of the buttocks. Some individuals experience this due to limited hip mobility, particularly in the form of tight hip flexors or poor ankle mobility. It can also occur if the individual is not properly activating their core muscles or lacks proper technique in the squat.

Buttwink is generally considered to be biomechanically disadvantageous and potentially increases the risk of lower back injury during squats. When the lower back rounds, it places more stress on the spinal discs, potentially leading to issues like herniated discs or lower back pain.

To address buttwink, individuals can work on improving their hip and ankle mobility through stretching and flexibility exercises. Strengthening the core muscles is also crucial to provide support and stability during squats. Additionally, making modifications to squat form, such as reducing the depth or widening the stance, may help minimize buttwink.

It is important to note that some degree of buttwink may be unavoidable for some individuals due to their unique anatomy. In such cases, it is recommended to work with a qualified strength and conditioning coach or physical therapist who can provide personalized guidance and exercise modifications to address any potential risks.
