Fatigue doesn’t ask for permission. It just shows up.

This week, you're likely running low. That’s by design. But when the body tires, posture fails first. That’s why today’s core work targets your anti-extension strength -- the ability to keep your ribs down, your spine stacked, and your breathing under control when everything else wants to fold.

This isn’t just damage control. You're gaining better posture under pressure. Stay tall when it counts.

Why this matters: Peak weeks demand anti-extension strength and rib cage control so your posture stays strong when you start to feel tired.

NOTES

  • RPE (rate of perceived exertion) should be 7.
  • For the half-kneeling press-out, mentally freeze your ribs so there's no rotation.
  • If needed, adjust the number of reps, time, or rounds to fit your fitness level.
  • If needed, rest 1-2 minutes between rounds.
  • Always do your warm-up to help prevent injuries.
  • Some video demonstrations may depict exercise tools other than a ruck - the same cues and form will still apply unless otherwise noted.

REMINDER:

  • Soft count: 1, 2, 3, 4 ... this is when both (or all) limbs perform the exercise at the same time.
  • Hard count: 1,1, 2, 2, 3, 3, 4, 4...this is when only one limb does work at a time.
  • Each Side: Do all reps on one side before switching to complete all reps on the other side.
