High Plank Knee To Elbow Alternating Sides Tutorial
High plank knee to elbow alternating sides is a dynamic core exercise performed from a high plank on your hands. From this position, you draw one knee toward the same side elbow, return to plank, then switch sides. This movement challenges your abs while also training shoulder stability and hip control.
This exercise is ideal for intermediate-level trainees who want to build a stronger, more functional core. Focus on slow, controlled movement, steady breathing, and keeping your hips level. It is often used in abs workouts, plank tutorials, and core stability guides.
Benefits
- Builds strong and visible abs
- Trains obliques through rotation control
- Improves plank stability and shoulder strength
- Enhances hip mobility and coordination
- Raises core endurance for longer sets
- Reinforces full-body tension and posture
Setup & Starting Position
Begin on the floor in a high plank position. Place your hands flat on the ground directly under your shoulders, fingers spread wide for a stable base. Your arms should be straight but not locked. Extend both legs straight behind you with your toes tucked under, feet about hip-width apart.
Create a straight line from your head through your shoulders, hips, and heels. Gently tuck your pelvis so your lower back stays neutral, not arched and not rounded. Engage your core by tightening your abs as if preparing for a light punch.
Before starting the first rep, check that your shoulders are stacked over your hands and your neck is long, eyes looking slightly ahead of your hands. Setup tip: push the floor away with your palms to activate your shoulders and upper back.
How To Do High plank knee to elbow alternating sides (Step-by-step)
- Set up in a strong high plank on your hands.
- Brace your core and keep your hips level.
- Lift your right foot and bend the knee.
- Bring your right knee toward your right elbow with control.
- Pause briefly near the elbow without collapsing.
- Return the right foot to the starting plank position.
- Repeat the same movement on the left side.
- Continue alternating sides at a steady tempo.
- Finish the set by holding a stable plank for a breath or two.
Form Cues
- Hands under shoulders
- Core tight before you move
- Hips stay level
- Slow knee drive
- Push the floor away
- Neck long and relaxed
Breathing & Bracing
Breathing correctly during high plank knee to elbow alternating sides helps you stay stable and avoid fatigue too early. Start by taking a calm inhale through your nose in the plank position to set your posture.
As you bring your knee toward your elbow, exhale slowly through your mouth. This exhale helps your abs tighten and supports spinal control. When you return the foot to the plank, gently inhale again before switching sides.
Think of bracing as tightening a wide belt around your waist. Your ribs should stay down and stacked over your hips. Avoid holding your breath. A simple rhythm is inhale in plank, exhale as the knee comes in, inhale as you reset. Repeat this pattern on every side.
Common Mistakes
- Hips lifting too high, fix it by tightening your abs before moving.
- Lower back sagging, fix it by tucking the pelvis slightly.
- Rushing the movement, fix it by slowing down each rep.
- Shoulders collapsing, fix it by pushing the floor away.
- Looking straight up, fix it by keeping your neck neutral.
- Turning it into a mountain climber, fix it by pausing and controlling the knee drive.
How It Should Feel
Quick Self-Check: During this exercise, you should feel steady tension through your abs and obliques, along with effort in your shoulders and hips. The movement should feel challenging but controlled.
Good signs:
- Strong abdominal engagement on every knee drive
- Minimal hip shifting side to side
- Shoulders feel stable and active
Warning signs:
- Sharp pain in the shoulders or lower back, stop immediately
- Pinching in the hips
If you feel it mostly in your neck or lower back, slow down, reset your plank alignment, and reduce range of motion until control improves.

Sample Workout
Core Stability Workout:
- High plank knee to elbow alternating sides, 8 to 10 reps, one rep equals right and left
- Dead bug, 10 reps
- Glute bridge hold, 30 seconds
- Side plank, 20 seconds per side
Rest 60 seconds and repeat for 2 to 3 rounds. Focus on clean technique rather than speed.
Progression Plan
Week 1: Perform 3 sets of 6 reps, one rep equals both sides. Move slowly and focus on perfect plank alignment. Rest 60 to 90 seconds between sets.
Week 2: Increase to 8 to 10 reps per set. Keep the same controlled tempo and try to reduce hip movement. Rest 60 seconds.
Week 3: Add a 1 second pause when the knee reaches the elbow. Perform 3 sets of 8 reps.
Week 4: Progress to an advanced variation like slow tempo knee to elbow or knee to opposite elbow. If form breaks down, repeat the previous week.
Only progress when you can complete all reps with stable shoulders and a neutral spine.
FAQ
How many reps should I do?
Start with 6 to 10 reps, where one rep includes both left and right sides.
Should my feet stay wide or close?
Hip-width feet give better balance. Wider is easier, closer is harder.
Can I use this exercise for abs fat loss?
It strengthens abs, but fat loss depends on overall calorie balance and training.
Why do my shoulders get tired first?
This is normal. Shoulder stability is a big part of high plank exercises.
