CORE

4 Core Challenges

Test your real core strength, not just your abs' looks

Why visible abs aren't the whole story

  • Visible abs mainly reflect low body fat, not core strength
  • You can have a strong core with no visible abs, and vice versa
  • Core strength is trainable separately from how your abs look
  • Real core strength shows up as stability under load, not just looks

4 challenges to try

  • Hollow hold: lie on your back, shoulders and legs slightly lifted, hold 30 seconds
  • Tuck L-sit: support on your hands, knees tucked, feet off the ground, hold 10 seconds
  • Plank: forearms and toes, straight line head to heels, hold 60 seconds
  • Side plank: forearm and feet stacked, hips lifted, hold 30 seconds each side

Scoring yourself

  • Complete all 4 with good form? Track your hold times as you improve
  • Struggling with one? That's the one to practice most this month
  • Shaking or losing form before time's up counts as the end of your hold
  • Retest every few weeks to track real progress

Good to know

  • Quality over duration. A shaky 60-second plank with sagging hips teaches your body the wrong pattern.
