When it comes to compound lifts like squats and overhead presses, mobility isn't just a nice-to-have. It's essential for performance and injury prevention. Today we are going to cover some of the key mobility requirements for the fitness athlete and what happens when restrictions occur.
Key Mobility Regions For Optimizing Athletic Performance
Hip Mobility
- Internal Rotation (15-20°)
- External Rotation (40-60°)
- Flexion (~120-140°)
Thoracic Spine
- Rotation (35-40° each direction)
- Extension (~20-30°)
Shoulder Mobility
- Flexion (180°)
- External rotation (90°)
- Internal rotation (~70°)
Ankle Mobility
- Dorsiflexion (20-30°)
Common Mobility Restrictions and Their Compensatory Patterns
1. Limited Ankle Mobility
Limited ankle (dorsiflexion) leads to forward trunk lean to maintain balance or achieve lower depth, which creates increased stress on the lumbar spine and potential injury.
2. Limited Shoulder and Thoracic Mobility
Restricted shoulder flexion and/or thoracic extension leads to excessive extension from the low back to achieve position, which creates increased stress on the lumbar spine and increased stress through anterior shoulder structures, and potential injury.
3. Limited Hip Mobility
Poor hip internal rotation causes the knees to track improperly, which creates increased stress on certain compartments of the knees and potential injury.
The key is addressing mobility limitations systematically rather than pushing through restrictions with poor form.
How Do I Know If I Have Limited Mobility?
Self-assessment can be a great first step toward identifying potential mobility restrictions.
The Overhead Squat Assessment
The overhead squat assessment is one of the most comprehensive mobility tests, revealing restrictions throughout your entire kinetic chain simultaneously.
Here's how to perform it correctly:
- Stand with feet shoulder-width apart
- Grab a broom or PVC pipe using a wide grip with straight elbows overhead
- Maintain a neutral spine
- Descend into a squat while keeping arms overhead
- Lower until thighs are parallel to the ground (or as deep as possible)
- Maintain weight in mid-foot to heel
- Keep chest up and spine neutral
- Feet turning out/heels rising: potential ankle mobility restriction
- Knees caving in: potential hip internal rotation limitation or weak glute musculature
- Forward torso lean: may indicate tight hip flexors or limited ankle mobility
- Arms falling forward: often signals restricted shoulder flexion or thoracic extension
- Lower back arching excessively: possible core weakness or hip mobility issues
What Do I Do If I Feel Tightness or Pain With This Assessment?
1. Consult a Professional
While self-assessment is valuable, a qualified physical therapist or movement specialist can:
- Provide objective measurements of your mobility limitations
- Identify subtle compensation patterns you might miss
- Rule out structural issues that might require special attention
- Create a personalized mobility program targeting your specific needs
2. Implement a Targeted Mobility Routine Into Your Warm-Up or Cool Down
Effective mobility work should be:
- Consistent: Daily practice yields better results than occasional intense sessions
- Specific: Target the exact restrictions you've identified
- Progressive: Gradually increase range and challenge over time
- Functional: Include movements that relate to your training goals
3. Lifestyle Modifications
Remember that daily habits significantly impact your mobility:
- Extended sitting can tighten hip flexors and may promote thoracic kyphosis
- Poor sleep posture can restrict shoulder and spine mobility
- Dehydration reduces tissue elasticity and joint lubrication
- Stress increases muscle tension and reduces movement quality
4. The Mobility Mindset
Approach mobility work with the same dedication you bring to your strength training. Rather than seeing it as an optional extra, consider mobility as the foundation that helps you to optimize your strength and athletic performance.
Exercise of the Month: Incline Ankle Knee Rocks
What Is It?
This is a GREAT exercise that can help you address deficits in your ankle mobility. Like we discussed, reductions in mobility in this joint can lead to increased forward trunk lean, which can cause increased stress to the lumbar spine. It can also significantly limit your ability to achieve full squat depth.
How to Perform
You will need a bench that has the ability to incline, as well as some weights (I typically use dumbbells or kettlebells).
- Bring the bench to an incline, and place one foot on the incline portion of the bench, weights in both hands.
- Slowly shift your body weight forward over the elevated ankle, with the goal of your knee tracking forward over your toes, while keeping your ankle flat on the bench.
- You can modify this exercise by increasing or decreasing the amount of incline on the bench, as well as increasing or eliminating the amount of weight you are holding. Just be sure to find something that challenges you appropriately.
