Tea Cups

Tea cups are a shoulder mobility drill. You take a light weight (dumbbell, plate, kettlebell, water bottle), hold it overhead, and rotate your arm through a full circle while keeping the elbow locked.

The name comes from the motion — like slowly tipping a cup of tea in a circle without spilling it.

Why it matters:

• Opens the shoulder through its full range of motion
• Warms up the rotator cuff
• Prepares the shoulder for overhead work (press, jerk, snatch)
• Zero to light equipment
• Trains shoulder stability at the end range

The key insight: most shoulder injuries come from ranges of motion you can’t control. Tea cups teach the shoulder to move through full range under light load. This is what protects the shoulder when you eventually put heavy weight overhead.

Setup:

• Stand tall, feet shoulder-width apart
• Hold a light weight (2.5-10 lbs / 1-5 kg) in one hand
• Press the weight overhead with the elbow locked

Execution:

1. From overhead position, slowly rotate the arm so the weight goes behind your head
2. Continue rotating — the weight comes down the back side
3. Then around and up the front side back to overhead
4. The elbow stays locked throughout
5. The motion is a full 360-degree circle
6. Repeat 5-8 times in one direction
7. Reverse direction for 5-8 more

Primary Points of Performance:

• Elbow stays locked
• Torso stays upright — no side-bending
• Slow, controlled motion
• Light weight — this is mobility, not strength
• Full range of motion (don’t cheat the circle)

Common Faults & Fixes:

Reps: 5-8 circles each direction per arm.

Training role:

• Shoulder mobility
• Rotator cuff warm-up
• Overhead prep before press, jerk, snatch
• Post-workout shoulder recovery
• Shoulder health for throwing athletes

Programming:

• 5-8 circles each direction, each arm
• 2-3 minutes total per session
• Before overhead work, throwing, or pressing
• Can be done daily

What it trains:

• Glenohumeral (shoulder) mobility
• Rotator cuff activation through full range
• Scapular stability
• Thoracic extension (as the arm goes behind)
• Core stability (keeping the torso upright)

Why it matters for athletes:

• Overhead athletes (throwers, swimmers, volleyball players) live and die by shoulder health
• Limited shoulder range of motion increases injury risk
• The shoulder is the most mobile joint in the body — and the most vulnerable
• Tea cups train the shoulder to move safely through the ranges you’ll need under load

Benchmarks:

• Full smooth circle with 2.5 lbs: baseline
• Full smooth circle with 5 lbs: intermediate
• Full smooth circle with 10 lbs: advanced
• Both directions equally smooth: mastery

Scaling:

• If range is limited: reduce weight to 2.5 lbs or use an unloaded arm
• If it hurts: stop. Shoulder pain is not something to push through.
• If one side is tighter: do more reps on that side

Shoulder mobility demands addressed:

• Flexion: arm straight overhead
• Extension: arm behind the body
• Abduction: arm out to the side
• Circumduction: full 360-degree circle — the essence of the tea cup
• External and internal rotation: the arm rotating at end range

The rotator cuff and mobility:

• The rotator cuff is four small muscles that stabilize the shoulder during movement.
• Tea cups activate all four as the arm circles through range.
• This is why tea cups are a warm-up drill — not just a stretch.
• Loaded mobility (light weight) increases activation vs. unloaded stretching.

Why shoulder mobility declines:

• Sedentary lifestyle (arms rarely go overhead)
• Heavy pressing without overhead mobility work
• Previous shoulder injuries that scarred tissue
• Age-related stiffening of the joint capsule

Programming notes:

• Perform before any overhead activity.
• Pair with scapular work (face pulls, YTW, wall slides) for full shoulder prep.
• Progress by increasing weight or adding a pause at the back position.
• Regress by removing the weight entirely — unloaded circles still help.

Research context:

• Overhead mobility (specifically shoulder flexion) is a limiter for the snatch, jerk, and overhead squat.
• Athletes with less than 170 degrees of shoulder flexion are at higher risk for shoulder injury.
• Loaded mobility drills like tea cups produce faster and more durable range of motion than static stretching.

Variations:

• Unloaded: baseline for very restricted shoulders
• Light plate: classic tea cup, 2.5-5 lbs
• Dumbbell or kettlebell: adds a stability challenge
• Slow eccentric: emphasize the descent for more range
• With band: partner stretches at end range

When NOT to do it:

• Acute shoulder injury: rest.
• Impingement symptoms (pinching at end range): reduce range to pain-free and consult a professional.
• Post-shoulder surgery: medical clearance required.
• Fresh dislocation: never push through pain.

Pairs well with:

• Pass-throughs (dynamic shoulder mobility)
• Wall slides (scapular control)
• Face pulls (posterior cuff)
• Band pull-aparts (upper back)
