Mobility
Mobility
Definition
Mobility is the ability of a joint to actively move through its full range, with control, stability, and strength. It combines 3 components:
- Flexibility: muscle and connective tissue length
- Motor control: ability to move precisely
- Joint stability: hold at end range
💡 Mobility ≠ flexibility. You can be very flexible (passive) but have limited mobility if you lack control or strength at end range.
Why mobility is crucial
5 major reasons:
- ✅ Technical performance: clean execution of deep squat, deadlift, etc.
- ✅ Injury prevention: fewer compensations, less wear
- ✅ Muscle recruitment: more range = more muscle activated
- ✅ Posture: better daily carriage
- ✅ Longevity: lasting practice of strength training
Mobility vs Flexibility vs Suppleness
| Concept | Definition | Example |
|---|---|---|
| Suppleness | Passive muscle length | Touching toes in flexion |
| Flexibility | Passive joint range | Assisted splits |
| Mobility | Active range + control + strength | Loaded deep squat |
Key joints in strength training
1. Hips
Crucial for squat, deadlift, hip thrust. Often stiff from prolonged sitting.
2. Ankles
Limited dorsiflexion = no deep squat, knee issues, compromised technique.
3. Shoulders
Mobility essential for overhead press, pull-ups, snatch and clean (Olympic lifting).
4. Thoracic spine
A stiff thoracic ruins posture, high-bar squat, bench press.
5. Wrists
Often neglected but essential for front squat, bench press, Olympic lifting.
10-minute mobility routine
To do daily or as warm-up:
| Exercise | Duration |
|---|---|
| World's greatest stretch | 3 reps per side |
| Cat-cow | 10 reps |
| Thoracic rotation | 10 per side |
| 90/90 hip mobility | 10 per side |
| Couch stretch | 1 min per side |
| Wall ankle mobilization | 15 reps per side |
| Dead hang | 30s |
How to progress in mobility
3 effective levers:
- ✅ Regular work: 10-15 min daily > 1h weekly
- ✅ Loaded end-range work: deep squats, RDL, weighted dips
- ✅ Specific methods: FRC, Kinstretch, Yoga, Animal Flow
💡 Best mobility comes from working full range WITH load. Deep squat builds more hip mobility than 100 passive stretches.
Common mistakes
- ❌ Confusing flexibility and mobility
- ❌ Doing static stretches thinking it's mobility
- ❌ Skipping mobility work when in a hurry
- ❌ Not training stability at end range
- ❌ Ignoring a stiff joint hoping it'll resolve itself
Key takeaways
Mobility is the invisible foundation of performance. 10-15 min daily targeted at your key joints (hips, ankles, shoulders, thoracic). Work full range with load. Without mobility, you plateau fast. With good mobility, you progress longer, further, injury-free.
