Protraction / Retraction
Front-to-back control builds the packed, level chin of good sprint posture and fights the head-back reach that shows up at the line.
Sprinting is a posture contest and the head leads it, from the held-down drive phase out of the blocks to the tall, relaxed carriage that lets top-end speed happen. This program builds the neutral strength that keeps the head from bobbing at max velocity, loads the rise out of the drive phase and the rotated positions of relay exchanges, then finishes with gun-speed reaction and stability against stride impact. When the head stays quiet, the arms and legs get to do their job.

Build the head control that holds sprint mechanics together, from the drive phase out of the blocks to a relaxed, tall posture at top speed.
Build the neutral strength and postural endurance of tall sprinting. The neck learns to hold the head still and level so nothing leaks out of the sprint up top.
Front-to-back control builds the packed, level chin of good sprint posture and fights the head-back reach that shows up at the line.
Long neutral holds train the quiet head of top-end speed, absorbing stride impact without a visible bob.
Repeated posture holds build the endurance that keeps your head tall in the final 30 meters, when everyone else is tightening up.
Rotational strength means a glance across lanes costs you nothing, the head turns and returns without dragging the shoulders along.
Advance whenAdvance when holds are steady for the full duration and head position stays fixed through every rep.
Load the positions racing actually forces. Controlled tempo work builds the rise out of the drive phase, and held rotation builds the checked-back look of a relay exchange.
The slow controlled tempo mirrors the gradual head rise out of the drive phase, earned stride by stride instead of popping up early.
End-range strength holds the flexed head position of the drive phase against the pull of wanting to look up too soon.
Held rotation is the relay exchange, head turned watching the incoming runner while your body starts accelerating forward.
A locked head over a working body mirrors full-effort arm drive, where the shoulders pump violently and the head cannot ride along.
Advance whenAdvance when tempo reps are smooth through the full range and rotated holds are solid at Heavy-adjacent loads.
Sharpen reaction and make posture impact-proof. Cue starts, fast pulses, and perturbation train a head that fires with the gun and stays level through every footstrike.
Cue-based reaction is the gun going off, the head snapping from set position into the drive angle without a wasted motion.
Fast diagonal pulses build neck stiffness at turnover speed, matching the rhythm of limbs cycling at maximum velocity.
Perturbation holds replicate stride impact at top speed, ground strikes arriving several times a second and trying to shake the head off line.
Recovering alignment against disruption trains the late-race correction, pulling the head back to neutral when fatigue starts tipping it back.
The 360 degree resistance head unit this program is built around, with the anchor and bands you need to train every direction from day one.

We call for an effort level instead of a specific weight, because the right resistance depends on you, the movement, and where you are in your training. For the sets and reps listed on each exercise, pick the resistance that makes the last few reps feel like the level shown.
You finish the set with several clean reps still in the tank. The work stays easy and fully controlled from the first rep to the last.
You could manage a few more reps at the end, but not many. The final reps take real effort while your form holds.
You reach the last prescribed rep with little or nothing left. Completing every rep with good form is genuinely hard.
These are starting points, not rules. Everyone is built differently, so adjust to fit you: size down if your form breaks before the final rep or a movement aggravates a symptom, and only size up once every rep feels smooth and pain free. When you are unsure, choose the lighter option.
