Day 10: The "Oblique Shortener" Side Plank Crunches

Welcome to Day 10! Yesterday was about resisting rotation; today is about controlling lateral power.

Why Side Plank Crunches for Runners?

When you run uphill or sprint for the finish line, your body uses a "side-crunching" motion to help drive your knees up. If your obliques are weak, your torso collapses, and your stride shortens. This move trains your side-core to stay "snappy" and strong under tension. It’s the secret to maintaining a powerful knee drive when your legs are tired.

The Mission:

• 3 Sets of 10 Reps (Per Side)

• The Key: This isn't about speed. It’s about the "squeeze" at the middle.

How to Perfect Your Form:

1. The Base: Start in your standard Side Plank (on your elbow).

2. The Extension: Reach your top arm over your head so your body forms one long line from your hand to your foot.

3. The Crunch: Bring your top elbow and your top knee together in the middle. Think about "crunching" your ribcage toward your hip.

4. The Reset: Slowly extend back out. Don't let your hips touch the floor! Keep that bottom hip pushed high the entire time.

5. Modification: If balancing on your feet is too hard, perform the move with your bottom knee resting on the floor for stability.

✅ DAY 10 CHECK-IN:

Once you’ve "shortened the obliques" on both sides, comment "SNAPPY" below!

The "Bottom Hip" Challenge: Did you notice your bottom hip trying to "sink" as you brought your elbow and knee together? That’s your glute medius working overtime! If you felt a burn in the hip that was touching the floor, you're doing it perfectly.

See you tomorrow for a move that will test your "Rear Engine" coordination!
