Mastering the Squat Depth

Squatting deep isn't just for show - it engages more muscle fibres and ensures better joint health. Research shows that deeper squats (below parallel) activate significantly more muscle mass in the quadriceps, glutes, and adductors compared to partial squats.

Common Mobility Issues

Ankle Dorsiflexion

If your heels lift off the ground, your ankles are likely tight. This forces the torso to lean too far forward, increasing shear forces on the lower back. You need approximately 20-30 degrees of ankle dorsiflexion for a proper deep squat.

Hip Internal Rotation

Tight hips prevent the "knees out" position, essential for creating space for the pelvis to drop. Limited hip mobility often manifests as the knees caving inward (valgus collapse) or an inability to reach depth without excessive forward lean.

Thoracic Spine Mobility

A rounded upper back in the bottom of the squat can indicate tightness in the thoracic spine. This affects bar position and overall stability.

Assessment Methods

Before addressing mobility, assess your current limitations:

• Ankle Test: Place your foot 4 inches from a wall, keep your heel down, and try to touch your knee to the wall. If you can't, ankle mobility is limited.
• Hip Test: Sit in a deep squat position with your feet flat. If you fall backward or can't maintain an upright torso, hip mobility is likely the issue.
• Overhead Squat: Hold a PVC pipe overhead and squat. This reveals mobility restrictions throughout the entire kinetic chain.

Drills to Improve Depth

1. Goblet Squat Holds: Sink into a deep squat and use your elbows to push your knees out. Hold for 30-60 seconds, focusing on maintaining an upright torso.
2. Ankle Wall Stretch: Place your foot 4-6 inches from a wall, keep your heel planted, and drive your knee forward. Hold for 30 seconds, repeat 3-5 times per side.
3. Hip Flexor Stretch: In a lunge position, push your hips forward while keeping your rear leg straight. Hold for 30-45 seconds per side.
4. Prying Goblet Squats: Hold a light weight and perform 10-15 slow, controlled squats, pausing at the bottom and gently "prying" your hips open.
5. Third World Squats: Practice sitting in a deep squat position daily, even if just for a few minutes while watching TV or using your phone.

Progressive Depth Training

If you can't squat deep with weight, don't force it. Instead:

1. Work on mobility daily (10-15 minutes)
2. Practice bodyweight squats to full depth
3. Gradually add load while maintaining depth
4. Use tempo squats (3-4 second descent) to improve control

Technique Check

Always film your sets from the side. Your hip crease should ideally drop below the top of your knee (this is "below parallel" or "ass to grass"). From the front, your knees should track over your toes without caving inward. Your torso should remain relatively upright, with minimal forward lean.

When Depth Isn't Possible

Some individuals have structural limitations (bone-on-bone contact, previous injuries) that prevent deep squatting. In these cases, work to your available range of motion and focus on other exercises to target the muscles that deep squats would normally hit.
