Core Crushing

Before beginning stated concerns about the air quality and stopping is not quitting if you need to sit out for a while. My intention was to focus on the core, which in my opinion, we often breeze through. I did not incorporate running or strength training as I wanted to keep strenuous sucking of wind to a minimum.

Card 1: COP (Warm-up) & Transition

Timing: ~8 Minutes All exercises In Cadence (IC)

  • Side Straddle Hops (SSH): 20 IC (Get the blood flowing)
  • Grass Pickers: 15 IC (Slow, deliberate reach to loosen the hamstrings and lower back)
  • Wonder Bras: 15 IC (Keep the shoulders warm and chest open)
  • Imperial Walkers: 15 IC (Gentle rotational core activation)
  • Little Baby Arm Circles: 10 forward IC, 10 reverse IC

Transition: Head straight to the turf. Grab a patch of grass and prepare to enter the Ring of Fire.

Card 2: The Thang – Part 1: “The Core Ring of Fire”

Timing: ~15 Minutes This is a high-volume, structural endurance block. Move immediately from one exercise to the next with minimal rest.

Round 1: Plank Mastery (5 Mins)

  • Standard Elbow Plank: 1 Min hold (Maintain a completely flat, neutral spine as shown above)
  • Plank Jacks: 1 Min IC (Core stability under dynamic movement)
  • Left Side Plank: 45 Sec hold
  • Right Side Plank: 45 Sec hold
  • Chilcutt Plank: 1 Min hold (On elbows, then up to hands on Q’s call)
  • Rest: 30 Seconds

Round 2: The Low-Angle Burn (6 Mins)

  • Flutter Kicks: 20 IC (Keep heels 6 inches off the ground, hands under the rump if needed)
  • Hello Dollies: 15 IC (Horizontal scissor kicks)
  • Rosalitas: 15 IC (Vertical leg splits)
  • LBCs (Little Baby Crunches): 25 IC (Look straight up at the sky, shoulder blades off the turf)
  • Freddie Mercurys: 20 IC (Bicycle crunches, executing with control)
  • Rest: 1 Minute

Card 3: The Thang – Part 2: “The 11s” & Mary

Timing: ~17 Minutes An F3 classic modified to keep the PAX in a tight footprint without running.

The 11s (Bodyweight Core & Lower Body)

Instead of running between spots, PAX will perform a Bear Crawl 5 yards forward to do Exercise B, then Crawl Bear (backward bear crawl) 5 yards back to do Exercise A.

  • Exercise A (Start): Big Boy Sit-ups
  • Exercise B (End): Squats
  • Ratio: Start with 10 Big Boy Sit-ups, bear crawl 5 yards, do 1 Squat. Crawl bear back, do 9 Big Boy Sit-ups, bear crawl, do 2 Squats. Continue this pattern until you reach 1 Big Boy Sit-up and 10 Squats (always adding up to 11).

Card 4: 6 Minutes of Mary (The Finisher)

Timing: ~5 Minutes Finishing strong. No stopping until the time hack.

  • American Hammer: 20 IC (The ultimate F3 finisher)
  • Coxswain: 15 IC (Bring knees to chest while balancing on the tailbone, then extend straight out)
  • Protractor: 2 Mins (Q calls out angles: 10 degrees, 45 degrees, 90 degrees, back down to 10. Hold it!)
  • Recover!

Card 5: CoT (Circle of Trust)

Timing: ~5 Minutes
