Are You Doing It Wrong? 10 Common Squat Mistakes and How to Fix Them
The squat is often hailed as the “king of all exercises”. Whether you are looking to build powerful legs, improve your strength training routine, or simply enhance your functional movement, the squat is your go-to move. However, despite its popularity, it is one of the most frequently performed exercises with poor technique.
Making subtle squat mistakes can do more than just stall your progress; it can lead to chronic lower back pain and compromise your long-term joint health. According to the NHS, performing resistance exercises correctly is vital for preventing musculoskeletal injuries. In this guide, we will break down the most common errors and provide expert-backed solutions to help you achieve proper form.
The Anatomy of a Perfect Squat
Before diving into the errors, it is essential to understand what a “good” squat looks like. A successful squat involves a complex coordination of hip mobility, ankle flexibility, and core stability. When these elements work in harmony, the load is distributed evenly across your muscles rather than your joints.
Research published in the Journal of Strength and Conditioning Research suggests that squatting through a full range of motion provides the most significant hypertrophic benefits. However, achieving this requires addressing the following hurdles.
1. Knees Caving Inwards (Valgus)
One of the most prevalent squat mistakes is “knee valgus”, where the knees collapse toward the midline of the body during the ascent or descent. This puts immense stress on the Anterior Cruciate Ligament (ACL). This often stems from weak hip abductors or muscle imbalances.
The Fix: Focus on “screwing” your feet into the floor. Imagine trying to rip the floor apart with your feet. This increases glute activation and keeps your knees in proper knee alignment. You can find more targeted glute exercises on Healthline to strengthen these stabilising muscles.
2. Lifting the Heels Off the Ground
If your heels rise as you descend, your weight shifts onto the balls of your feet, overloading the knee joint. This is usually a sign of poor ankle flexibility, specifically restricted dorsiflexion.
The Fix: Incorporate dynamic ankle stretches into your warm-up. If mobility is a persistent issue, clinical studies suggest that using weightlifting shoes with a raised heel can provide temporary assistance while you work on your long-term mobility.
3. The “Butt Wink” (Posterior Pelvic Tilt)
The “butt wink” occurs when the pelvis tucks under at the bottom of the movement, causing the lower spine to round. This is a recipe for lower back pain and potential disc issues. Experts at the Cleveland Clinic emphasize that maintaining a neutral spine is critical during heavy lifting.
The Fix: Only squat as deep as your hip mobility allows while maintaining a flat back. Gradually increase your squat depth as your flexibility improves. Understanding your hip anatomy can help you determine the best stance width for your body type.
4. Neglecting Core Stability
Many lifters treat the squat as purely a leg exercise, forgetting that the torso acts as the bridge between the weight and the floor. Without core stability, the spine can buckle under pressure.
The Fix: Utilise the “Valsalva manoeuvre”—taking a deep breath into your belly and bracing your abdominals as if you’re about to be punched. For those lifting near their maximum capacity, a weightlifting belt can offer additional intra-abdominal pressure, as noted by the American Council on Exercise.
Quick Correction Guide
Use the table below to identify your specific squat mistakes and the immediate steps to rectify them.
| Mistake | Primary Cause | Quick Fix |
|---|---|---|
| Knees Caving In | Weak Glutes / Hip Abductors | Drive knees out; use resistance bands. |
| Heels Rising | Poor Ankle Mobility | Stretch calves; use squat shoes. |
| Leaning Too Far Forward | Tight Hips / Weak Back | Keep chest up; engage lats. |
| Rounding Lower Back | Inadequate Core Bracing | Learn the Valsalva manoeuvre. |
5. Looking Straight Up
It is a common myth that looking at the ceiling helps you stay upright. In reality, hyperextending your neck puts unnecessary strain on the cervical spine and disrupts your overall balance.
The Fix: Maintain a “packed” neck. Pick a spot on the floor about two metres in front of you and keep your gaze fixed there. This promotes a neutral spine from your head to your hips, a key component of injury prevention recommended by the British Journal of Sports Medicine.
6. Lack of Depth
Partial squats lead to partial results. Stopping too high reduces muscle activation in the hamstrings and glutes, placing most of the load on the quadriceps. According to ScienceDirect, full-depth squats result in better overall lower-body development.
The Fix: Aim for the hip crease to drop just below the top of the knee. If you struggle with this, try goblet squats to help counterbalance your weight and allow for a deeper range of motion.
How to Warm Up for a Barbell Squat
Jumping straight under a heavy barbell squat is one of the most dangerous squat mistakes you can make. A proper warm-up “greases the groove” of the movement pattern. The Mayo Clinic suggests that warming up increases blood flow and prepares the nervous system for work.
- 90/90 Hip Switches: To improve internal and external hip rotation.
- Cat-Cow Stretch: To mobilise the spine.
- Bodyweight Squats: To practice the movement pattern.
- Ankle Circles: To prepare the joints for dorsiflexion.
The Importance of Professional Guidance
While self-correction is valuable, having an expert eye can be transformative. The National Academy of Sports Medicine highlights that subtle deviations in biomechanics are often hard to feel but easy to see. Consider filming your sets or working with a certified trainer to identify muscle imbalances early.
For those with pre-existing conditions, consulting a physical therapist is essential. Protecting your joints is a lifelong commitment, as advocated by the Arthritis Foundation. Squatting is a fundamental human movement, and when done correctly, it supports joint health well into old age.
Key Takeaways for Better Squats
- Prioritise Form Over Weight: Never add plates to the bar if your technique is failing.
- Master Mobility: Spend time daily on your ankles and hips.
- Engage Your Core: Treat the squat as a full-body lift.
- Find Your Stance: Everyone’s anatomy is different; experiment with foot width and toe angle.
- Stay Consistent: Strength training is a marathon, not a sprint.
By avoiding these squat mistakes, you turn a potentially risky exercise into a powerful tool for functional fitness. As Harvard Health notes, functional movements like the squat help maintain independence and prevent falls as we age.
Frequently Asked Questions (FAQs)
Are squats bad for your knees?
No, when performed with proper form, squats actually strengthen the muscles around the knee joint, providing better support. Problems usually arise from existing injury prevention failures or incorrect knee alignment during the lift. Biomechanical studies in Nature show that the knee joint is well-adapted to handle the loads of a squat.
Should I wear a weightlifting belt?
A weightlifting belt is a tool, not a crutch. It is most beneficial when lifting near-maximal loads to increase intra-abdominal pressure. However, you should still develop your natural core stability without relying on a belt for every set. Refer to the Cochrane Library for more on physical activity supports.
How deep should I squat?
Ideally, you should aim for “parallel”—where the hip crease is level with the knee. However, the best squat depth for you is the maximum range you can achieve without your lower back rounding or your heels lifting. Quality of movement always trumps quantity of depth.
