STILL IN MOTION
Because slowing down isn’t in the plan.
TUESDAY DEEP DIVE: THE STRETCH
Sunday’s issue introduced the Side-Lying Thoracic Rotation. Today we expand with two additional variations that address different levels of thoracic restriction and different levels of comfort — including a fully pain-accommodating version for flare-up days.
Thoracic rotation is one of the first ranges of motion to deteriorate in adults over 60, and its loss creates a cascade of problems: the lumbar spine absorbs rotation it wasn’t designed to handle, the shoulders lose range in overhead movement, and the neck compensates by over-rotating to make up for what the thorax can’t do. The variations below address this at three levels of mobility and comfort.
10K Steps Is a Myth–Try This Instead
When motivation is lacking, jumping into heavy routines is the fastest way to burn out. That’s why millions of people are turning to walking as the foundation of their fitness journey.
Walking lets you enjoy the outdoors, clear your head, and practice mindfulness. It’s simple, sustainable, and can support lasting weight loss if you know how much you need. The “10,000 steps a day” rule is outdated; everyone’s lifestyle is different.

VARIATION 1: SEATED CHAIR ROTATION (MOST ACCESSIBLE)
Best for: High-discomfort days, people with significant thoracic restriction who find side-lying positions uncomfortable, or as a standalone desk mobility drill used throughout the day.
How to do it:
Sit tall in a firm chair, feet flat on the floor, arms crossed over the chest
Keeping the pelvis stationary and the lower back still, rotate the torso slowly to the right
Go only to the comfortable end range — do not force
Hold 3 seconds, feeling the thoracic spine doing the work
Return to center, rotate left
8–10 reps each direction, 2 rounds
Pain management note: On days when category-two discomfort (from Sunday’s framework) is present in the thoracic region or ribs, this is the appropriate rotation variation. Seated, unloaded, and gravity-neutral. It maintains the rotation signal without loading the symptomatic tissue.
VARIATION 2: SIDE-LYING THORACIC ROTATION (INTERMEDIATE)
This is Sunday’s featured stretch. Key refinements:
The pillow between the knees is not optional — it maintains hip stacking and prevents the pelvis from rotating with the spine
The eyes follow the rotating arm — the cervical spine and thoracic spine should rotate together as one unit
At the end range, take 3 to 5 slow breaths before returning. Each exhale typically allows 1 to 2 additional degrees of rotation
The return movement should be as slow and controlled as the rotation out — not a drop back to center
If you hear or feel clicking in the thoracic spine during rotation, this is usually joint cavitation (the same mechanism as knuckle cracking) and is not a cause for concern
VARIATION 3: QUADRUPED THORACIC ROTATION (THREAD THE NEEDLE)
Best for: People with good thoracic range of motion who want a deeper rotation stimulus, or those who find that the side-lying version doesn’t produce sufficient rotation range.
How to do it:
Begin on hands and knees, wrists under shoulders, knees under hips
Place your right hand behind your head
Rotate the right elbow toward the left arm (threading it under the body) — the right shoulder and thoracic spine follow
Then rotate in the opposite direction, opening the right elbow toward the ceiling as far as possible
The hips stay still throughout — this is thoracic rotation, not hip rotation
8–10 reps per side, 2 rounds
What distinguishes this from the other variations: The quadruped position locks the pelvis in place more effectively than any other starting position, which means the rotation that occurs must come from the thoracic spine rather than being borrowed from the lumbar or hip regions. This makes it the most specific variation for true thoracic mobility development.
Relevant connection: This variation directly improves the rotational range available during the Golf Swing, paddle sports, tennis, and any sport involving upper body rotation. It also improves the range available during the single-arm dumbbell row from Issue #32 — where thoracic rotation allows the shoulder blade to fully retract.
Stop These 6 Lash Mistakes
Thinner lashes after 50 aren’t “just aging”
It is also the way you're taking care of them...expired mascara, waterproof formulas, heated curlers, harsh preservatives, and more.

COMING UP
Thursday we expand the Step-Up into three progressions — including the lateral variation that targets hip abductor strength, and a method for using step height as a pain-management tool that works regardless of which knee or hip is the current complaint.
