DAY 1
The Impingement Self-Test
Today you establish your baseline. The Hawkins-Kennedy test reproduces impingement pain by passively flexing your shoulder to 90° and forcing internal rotation. Perform it on both sides. Document where you feel pain — front of shoulder suggests subacromial impingement; top of shoulder suggests AC joint involvement. This distinction determines your corrective priority for the week.
Expected ResultYou'll identify which shoulder is more affected and confirm whether overhead positions reproduce your pain. This baseline measurement becomes your progress reference point.
DAY 2
Unlock Your Scapular Mechanics
Your shoulder blade (scapula) must upwardly rotate 60° for every 120° of humeral motion during overhead reach. If it's stuck — and in desk workers, it almost always is — the humerus jams into the acromion. Wall slides with scapular focus: back against wall, arms in goalpost position, slide up while pressing forearms into wall. 3×10 reps. Feel the lower traps engage at the top.
Expected ResultYou'll notice your scapulae moving more freely. The wall slides retrain the serratus anterior and lower trapezius — the two muscles most responsible for scapular upward rotation.
DAY 3
Open Your Thoracic Spine
A stiff thoracic spine forces your shoulders to compensate. Research by Ludewig & Reynolds (2009) showed that thoracic kyphosis directly increases subacromial impingement risk. Thread the Needle: start on all fours, reach one arm under your body, rotate through mid-back, then open to the sky. 8 reps per side. Follow with 30-second foam roller extensions at three thoracic levels.
Expected ResultYour mid-back will feel noticeably less rigid. Thoracic extension and rotation restore the 35° of rotation your shoulders need for healthy overhead mechanics.
DAY 4
Activate Your Rotator Cuff
The four rotator cuff muscles (supraspinatus, infraspinatus, teres minor, subscapularis) function as dynamic stabilizers that center the humeral head in the glenoid fossa. When they fatigue or fire late, the humerus migrates superiorly during overhead motion — directly into the impingement zone. Banded external rotation: elbow pinned to side, rotate forearm out against band resistance. 3×15 per side. Slow and controlled — 2 seconds out, 3 seconds back.
Expected ResultYou'll feel a deep burn in the posterior shoulder. This is infraspinatus and teres minor waking up. Stronger external rotation prevents the anterior-superior humeral migration that causes impingement.
DAY 5
Fix Your Overhead Press Pattern
Most men press with excessive lumbar extension and insufficient scapular upward rotation — a recipe for impingement. The fix: ribcage down (engaging anterior core), slight forward lean, and initiating the press with scapular elevation before humeral flexion. Practice with band overhead press: 3×10, focusing on finishing with ears between your biceps, not behind them.
Expected ResultThe overhead position will feel significantly less threatening. You're retraining the motor pattern so your shoulder clears the acromion instead of grinding against it.
DAY 6
The Daily Maintenance Protocol
Today you consolidate everything into a 10-minute daily routine you'll keep after the challenge. Sequence: 30 seconds lacrosse ball pec minor release → 10 wall slides → 8 thread the needle per side → 15 banded external rotations per side → 10 band overhead presses. This is your insurance policy against impingement recurrence. Perform it before any overhead training session.
Expected ResultYou now have a complete prehab routine. Athletes who perform scapular and rotator cuff activation before overhead work reduce impingement symptoms by 62% (Cools et al., 2014).
DAY 7
Your Shoulder Longevity Plan
Retest your Hawkins-Kennedy sign from Day 1. Compare. Most participants report 40-60% pain reduction in overhead positions by this point. Your long-term protocol: daily maintenance routine from Day 6, thoracic mobility 3× per week, rotator cuff strengthening 2× per week, and overhead movement screening monthly. Avoid prolonged overhead holds (>30 seconds) until full pain-free range is confirmed.
Expected ResultMeasurable improvement in overhead range and reduced impingement pain. You now understand your shoulder mechanics well enough to self-correct before problems escalate.
