# Mobility Assessment
 Complete ROM self-tests to get a mobility score and personalized foam rolling recommendations.

               
## Mobility Assessment
Self-assess each movement pattern and rate your performance 1-5.

Shoulder Reach

Reach one hand over your shoulder and the other behind your back. How close can your hands get?

12345Overlapping hands

Hamstring Flexibility

Lying on your back, raise one straight leg. How high can you go?

1234545-90°

Hip Flexor

In a deep lunge, how close is your back knee to the floor and how upright is your torso?

12345Moderate depth

Thoracic Spine Rotation

Seated, cross arms over chest. Rotate your upper body. How far can you turn?

12345Moderate (45-60°)

Ankle Dorsiflexion

Knee-to-wall test: how far can you position your foot from the wall while keeping heel down?

123458-10cm

This assessment runs you through a set of simple range-of-motion self-tests — hip flexion, thoracic rotation, ankle dorsiflexion, and others — and scores each one against functional benchmarks. The result is a mobility profile that shows you exactly where restrictions are limiting your movement and which foam rolling sequences will address them.

     
## How This Tool Works

## Frequently Asked Questions
   
### How do I test my own mobility at home?
 The most reliable self-tests measure joint range of motion against functional benchmarks. This assessment guides you through hip flexion, thoracic rotation, shoulder mobility, and ankle dorsiflexion tests using your body as the measuring tool — no equipment required. Each test takes under 60 seconds.

  
### What is a good mobility score?
 Functional mobility means having enough range of motion to perform daily activities and training without compensation patterns. This assessment scores each joint against validated benchmarks: hip flexion above 120 degrees, thoracic rotation above 45 degrees each side, and ankle dorsiflexion of at least 10-15 degrees. Restrictions in any of these areas are addressable with consistent foam rolling and stretching.

  
### Can foam rolling improve mobility?
 Yes. Research published in Frontiers in Physiology found that foam rolling improves flexibility by 10% in a single session (Wiewelhove et al., 2019). Regular rolling reduces fascial adhesions that restrict range of motion. 321 STRONG recommends combining foam rolling with dynamic stretching for best results.

  
### How often should I do a mobility assessment?
 Retest every 4-6 weeks. Mobility improvements happen gradually, and testing too frequently makes progress hard to see. Consistent foam rolling and targeted stretching, done 5 days per week for 4 weeks, typically produces measurable range-of-motion gains you'll see in your retest score.

  
### What causes poor mobility?
 The main contributors are fascial adhesions from repetitive loading, muscle shortening from extended periods in fixed positions (sitting), scar tissue from old injuries, and joint capsule tightness. Foam rolling addresses the first two directly. Mobility restrictions from scar tissue or joint capsule tightness may need professional intervention.
