Trainer's Eye
Holds, side walls and carries — the trunk trained the way life actually loads it.
The trunk's job is to resist movement, not create it. That is why planks and carries beat sit-ups for most people.
Picking something up and walking with it loads the grip, trunk, hips and heart at once.
The diaphragm is a trunk stabiliser: a long exhale plus a light brace steadies you under load.
Three couplets · two rounds · twelve minutes · a day of return
Hands down, feet back to a plank, feet in, stand tall — no jump.
Easier step back and in · Harder add the jump
Low back pressed down, shoulders and heels hover, breathe steadily.
Easier knees bent · Harder legs straight
Push off the outside foot, cover distance, land and stick for a beat.
Easier small hop · Harder further
Elbow under the shoulder, hips high, body in one straight line.
Easier knees down · Harder top leg raised
Two heavy bags; walk ten steps out and back, tall and quiet.
Easier lighter · Harder heavier
Chest tall, lean back slightly; rotate through the ribs, feet can stay down.
Easier feet down, no weight · Harder hold a bag
Each couplet: 60 s scored → the strength set → 10 s to move on. Done at 12:00.
