Front Plank Variation: Knee To Elbow
Front Plank Variation: Knee To Elbow
A dynamic plank drill combining trunk stability with controlled hip flexion—drive the knee toward the same-side elbow without hip sway.
Muscles Targeted
Anterior core (transverse abdominis/rectus), obliques, hip flexors (as movers), serratus anterior, and shoulder stabilizers.
Key Benefits
- Challenges stability while the hips move
- Trains anti-rotation control with a unilateral drive
- Builds shoulder endurance in a high plank position
- Great bridge from static planks to dynamic control
Equipment Needed
Mat or soft surface.
How to Perform Front Plank Variation: Knee To Elbow
- Set up in a strong high plank (hands under shoulders).
- Brace your trunk and keep hips level.
- Drive one knee forward toward the same-side elbow (or as close as you can).
- Return slowly and repeat, alternating sides.
Programming Options
- 6–10 reps per side, 2–4 sets
- Or 20–30 seconds of controlled alternating reps
- Rest 45–90 seconds between sets
Why This Variation Works
You’re forcing dissociation: the hip flexes while the spine stays controlled. That’s a high-value pattern for runners and athletes who need stable trunks with moving limbs.
When to Use It
Core circuits, athletic warm-ups, and progressions after you can hold a clean plank without sagging.
Frequently Asked Questions
Should my hips rotate as I bring the knee forward?
No. Slow down and shorten the range until hips stay level.
What if I feel it mostly in my shoulders?
Take longer rest, widen the feet, or drop to forearms. Keep the plank strong before adding speed.
How do I progress it?
Move slower, pause at the top, narrow the feet, or increase total reps while keeping perfect control.
