Low Plank Knee To Elbow Tutorial
Low plank knee to elbow is a bodyweight core exercise performed from a forearm plank where you draw one knee toward the same side elbow. It trains deep abs, obliques, and shoulder stability while demanding strong bracing.
This move is best for intermediate trainees who want a tougher plank variation and a guide on how to build anti-rotation strength. Focus on slow control, steady breathing, and keeping your hips level as the leg moves.
Benefits
- Builds strong abs and obliques
- Improves plank stability and control
- Challenges anti-rotation strength
- Strengthens shoulders and upper back
- Reinforces proper bracing technique
- Requires no equipment or space
Setup & Starting Position
Begin on the floor in a low plank position. Place your forearms on the ground with elbows directly under your shoulders. Your forearms should be parallel, palms resting on the floor. Extend both legs straight back with toes tucked under.
Create a straight line from the back of your head through your shoulders, hips, and heels. Gently tuck your pelvis so your lower back is neutral, not arched or rounded. Squeeze your glutes and lightly pull your ribs down to lock your torso in place.
Before starting the first rep, shift your weight evenly between both forearms and toes. Take a calm breath and brace your core as if preparing for a cough.
Setup tip: If your hips are higher than your shoulders, walk your feet slightly back to re-align your body.
How To Do Low plank knee to elbow (Step-by-step)
- Set up in a strong low plank on your forearms.
- Inhale lightly and brace your abs.
- Exhale as you draw your right knee toward your right elbow.
- Keep hips square and shoulders steady.
- Pause briefly near the elbow without touching.
- Return the right leg to full extension with control.
- Repeat on the left side.
- Continue alternating sides for the set.
Form Cues
- Forearms press down evenly
- Hips stay level
- Slow and controlled knee drive
- Ribs down, abs tight
- Neck long and relaxed
- Move one leg at a time
Breathing & Bracing
Proper breathing makes this exercise far more effective. Start by taking a calm inhale through your nose in the plank position. As you move the knee toward the elbow, exhale slowly through your mouth and tighten your abs.
Think of drawing your belly button gently inward and wrapping your abs around your spine. This bracing should feel firm but not rigid. Avoid holding your breath, as that reduces control and endurance.
A simple rhythm to follow is inhale in plank, exhale during the knee drive, inhale as the leg extends back. Keep your rib cage stacked over your hips throughout. If you feel your lower back moving, reset your brace and slow the movement.
Common Mistakes
- Hips twisting side to side, slow down and brace harder.
- Lower back sagging, squeeze glutes and tuck pelvis.
- Rushing the reps, use a controlled tempo.
- Shoulders collapsing, press forearms firmly into the floor.
- Neck craning forward, keep gaze down.
How It Should Feel
Quick self-check:
Good signs: You feel steady tension in the abs and obliques, shoulders working to stabilize, and glutes lightly engaged. Breathing feels controlled even as fatigue builds.
Warning signs: Sharp pain in the shoulders, elbows, or lower back means you should stop. Excessive hip rocking or back strain also signals loss of control.
If you feel it mostly in your neck, relax your shoulders and lengthen your spine. If you feel it in your lower back, slow down, shorten the knee drive slightly, and re-brace your core before continuing.

Variations
Easier
- Low plank knee lift: From a forearm plank, lift one knee slightly without reaching the elbow.
- Low plank hold: Hold a standard forearm plank to build base strength.
Harder
- Slow tempo low plank knee to elbow: Take 3 to 4 seconds to bring the knee in and back.
- Low plank knee to elbow with pause: Pause for 2 seconds near the elbow to increase tension.
Sample Workout
Core Stability Circuit
- Low plank knee to elbow, 10 reps per side
- Dead bug, 8 reps per side
- Glute bridge hold, 30 seconds
Rest 60 seconds and repeat for 2 to 3 rounds. One rep of low plank knee to elbow equals one knee drive on each side.
Progression Plan
Week 1: Perform 2 to 3 sets of 8 reps per side. Use a steady tempo and focus on perfect alignment. Rest 60 to 90 seconds between sets.
Week 2: Increase to 10 to 12 reps per side or add a 1 second pause near the elbow. Keep rest the same.
Week 3: Slow each rep to a 3 second knee drive and 3 second return. Reduce rest slightly if form remains strong.
Progress only when you can keep hips level and breathe smoothly. If form breaks down, repeat the current week until control improves.
FAQ
How many reps should I do per side?
Most people start with 8 to 12 controlled reps per side.
Should my knee touch my elbow?
Touching is optional. Focus more on control and keeping hips level.
Can I do this every day?
Yes, as long as your form stays solid and soreness is minimal.
Why do my hips rotate?
Rotation usually means the movement is too fast or your core brace is lost.
Summary
The low plank knee to elbow is a powerful way to take your plank training further. It builds real-world core strength by resisting movement while your limbs work.
Stay patient, move with control, and prioritize quality over speed. When done well, this exercise becomes a reliable tool for stronger abs, better stability, and improved overall body control.
