Legs
Cat Plank
A controlled isometric hold that builds quad endurance and core stability through a hovered-knee position.
How to perform.
Follow the sequence — setup is half the lift.
Begin on all fours in a tabletop position with your hands directly under your shoulders and knees under your hips.
Engage your core by drawing your navel toward your spine while maintaining a flat, neutral back.
Tuck your toes under and press your weight into the balls of your feet and the palms of your hands.
Lift your knees exactly one to two inches off the floor while keeping your shins parallel to the ground.
Hold this static position while breathing deeply, ensuring your hips do not rise and your head remains in line with your spine.
Lower your knees back to the floor with control to complete the repetition.
Common mistakes.
Fix these first — they cost reps, kilos, and joints.
- Hiking the hips too high which shifts tension away from the quads
- Allowing the lower back to arch or sag toward the floor
- Letting the knees drift too far above the two-inch height margin
- Rounding the upper back or dropping the head between the shoulders
Muscles worked.
The primary movers do the work; the stabilizers keep the path honest.
