If you’ve been working on your squats and noticed your lower back tucking under as you descend, you might be dealing with a common issue called “butt wink.” This movement pattern can affect your squat performance, increase injury risk, and limit your gains. But what exactly causes butt wink, and how can you fix it? Let’s break it down in simple, easy-to-read terms.


Common Causes of Butt Wink

There are several reasons why you might experience butt wink during squats. Let’s explore the most common causes:

1. Lack of Hip Mobility

Poor hip flexibility is one of the leading causes of butt wink. If your hip joints lack the necessary range of motion to reach a deep squat, your body compensates by rounding the lower back. Stretching and mobility exercises targeting the hip flexors, glutes, and hamstrings can improve your squat depth without compromising your spine.

2. Tight Hamstrings

Tight hamstrings pull on the pelvis, causing it to tilt posteriorly (backward) as you descend into the squat. This tilt leads to a butt wink. Incorporating hamstring stretches, such as standing forward folds or hamstring-focused yoga poses, can help loosen up these muscles and prevent the tuck.

3. Poor Ankle Mobility

Ankle mobility plays a crucial role in squat depth. Limited dorsiflexion (the ability to flex your ankle upward) can prevent you from achieving proper squat form, forcing compensations that lead to butt wink. Exercises like ankle dorsiflexion drills and calf stretches can enhance your ankle mobility.

4. Weak Core Muscles

A weak core affects your ability to stabilize your pelvis and lower back during squats. Strengthening your core muscles, particularly the deep stabilizers, can help you maintain a neutral spine throughout the movement.

5. Incorrect Squat Depth

Sometimes, butt wink occurs when people squat deeper than their body allows. Everyone has a different range of motion, and trying to push beyond your limits can cause your pelvis to tilt. Learning to recognize your optimal squat depth can minimize the risk.


How to Fix Butt Wink

Now that you know the causes of butt wink, let’s look at some practical steps to correct it.

1. Improve Hip Mobility

Incorporate dynamic and static stretches into your routine to improve hip flexibility. Try exercises like:

  • Hip flexor stretches
  • 90/90 hip mobility drills
  • Butterfly stretches

2. Stretch and Strengthen the Hamstrings

Loosen up tight hamstrings with regular stretching and strengthen them through exercises like Romanian deadlifts and hamstring curls. Balancing flexibility and strength can help prevent pelvic tilting.

3. Work on Ankle Mobility

Enhance your ankle flexibility with drills like:

  • Calf stretches against a wall
  • Ankle dorsiflexion stretches using a resistance band
  • Deep squat holds with heel elevation

4. Strengthen Your Core

Core stability is critical for maintaining a neutral spine. Include core exercises such as:

  • Planks and side planks
  • Dead bugs
  • Bird dogs

These movements target deep core muscles that help stabilize your lower back and pelvis.

5. Adjust Squat Depth

Find your optimal squat depth by descending only as far as you can maintain a neutral spine. Use a mirror or film yourself to monitor your form. Gradually increase your depth as your mobility improves.


Proper Squat Form Tips

To prevent butt wink and ensure safe squatting, follow these form tips:

  1. Engage Your Core: Brace your core as if preparing for a punch to protect your spine.
  2. Keep Your Chest Up: Avoid leaning too far forward; maintain an upright torso.
  3. Use Your Hips: Initiate the squat by pushing your hips back rather than bending your knees first.
  4. Maintain a Neutral Spine: Keep your back flat and avoid excessive arching or rounding.
  5. Track Your Knees Over Your Toes: Ensure your knees follow the direction of your toes to avoid knee strain.
