Knee Push-up: How to Do It Correctly

Step-by-step form

1. Setting up

   Kneel on the floor and place your palms approximately 5 cm wider than shoulder-width apart, fingers pointing forward. Position your knees directly under your hips, with the ankles lifted off the floor or crossed behind you. Maintain a neutral cervical spine, directing your gaze to a point roughly 30 cm in front of your hands. Actively press the palms into the floor to achieve slight scapular protraction before the movement begins.

2. The movement

   Bend your elbows at roughly a 45-degree angle away from your torso, lowering your chest to within 2-3 cm of the floor — complete this eccentric phase over 2-3 seconds. After a brief pause at the bottom, drive your palms into the floor to return to the start; the concentric phase should take 1-2 seconds. At the top, elbows reach full extension without locking out. Each rep returns the torso to the exact same elevated start position before the next descent begins.

3. What stays in line

   Shoulders, hips, and knees must fall on a single diagonal plane — not parallel to the floor but in one continuous line from head to knee. Elbow flare should be limited to 30-45 degrees from the torso; wider flare shifts load excessively onto the anterior shoulder capsule. The lumbar spine stays neutral throughout — no anterior or posterior pelvic tilt. The cervical spine is an extension of the thoracic spine; the chin should neither tuck hard to the chest nor jut upward.

4. Breathing

   Inhale in a controlled manner over 2-3 seconds throughout the entire descent — allow the diaphragm to fully expand. At the bottom pause (approximately 0.5 seconds), avoid holding your breath; a passive momentary pause is sufficient. Exhale forcefully through your mouth over 1-2 seconds during the push-up phase. At the top, take approximately 0.5 seconds to re-establish normal breathing rhythm before initiating the next rep.

Common mistakes

1) Hip sagging: The torso dips in the middle instead of holding a diagonal line — detect this by filming from the side or using a mirror. 2) Excessive elbow flare (approaching 90 degrees): This overloads the anterior shoulder capsule; consciously track elbows at 45 degrees from the torso to self-correct. 3) Head dropping or craning upward: Manifests as neck flexion or hyperextension — fix by anchoring your gaze to a fixed reference point on the floor approximately 30 cm ahead.

Recommended sets and reps

Recommended sets and reps

Beginner: 2 sets × 6-8 reps. Intermediate: 3 sets × 10-12 reps. Advanced: 4 sets × 15 reps performed at a 3-1-2-0 tempo.

Tempo

Recommended tempo: 3-1-2-0. Three seconds for the descent (eccentric), a 1-second pause at the bottom, 2 seconds for the push-up (concentric), and zero pause at the top before the next rep. Beginners may start at 2-0-1-0; advanced users can apply a 4-2-2-0 tempo for greater eccentric load.

How often

Three sessions per week is sufficient for optimal adaptation; a minimum of 48 hours of recovery must be allowed between sessions. In strength-focused programs, frequency can be increased to four sessions per week, but sessions should never be scheduled on consecutive days and the inter-session gap should not fall below 36 hours.

What it trains

Develops upper-body pushing strength with direct functional carryover to daily pushing tasks such as opening doors or sliding objects across surfaces. Increases contractile capacity of the pectoralis major and anterior deltoid, establishing a structural foundation for progressing to more demanding push-up variations such as standard or close-grip push-ups. Bilateral upper-limb loading measurably improves shoulder joint stability and scapular motor control over time.

If something hurts

Knee

Knee pain during this exercise is most commonly caused by compressive pressure from the patella against a hard surface. Use a folded yoga mat or dedicated knee pad to distribute contact force; positioning the knees at a very slight inward angle rather than directly forward may also reduce discomfort. Stop immediately if the pain is sharp, burning, or increases with movement, and consult a healthcare professional.

Lower back

Lower-back pain typically results from lumbar hyperextension or excessive hip sagging, both of which place the lumbar spine under compressive load. Re-check pelvic position: a mild glute contraction helps restore neutral pelvic alignment without over-flattening the lumbar curve. Stop the exercise if the pain is sharp, radiating, or extends into the leg, and consult a healthcare professional.

Shoulder

Shoulder pain most commonly indicates impingement syndrome, which is aggravated by excessive elbow flare. Narrow hand placement to shoulder-width and consciously bring elbows closer to the torso to increase subacromial space and redistribute load. If pain persists after the exercise or presents as a sharp sensation during movement, stop immediately and consult a healthcare professional.

When to skip it

Acute carpal tunnel syndrome or wrist tenosynovitis: the weight-bearing wrist position increases compressive stress on the median nerve and tendons. Active lateral or medial epicondylitis: concentric loading of the elbow extensors can worsen symptoms. Acute rotator cuff tear (grade 2-3) or subacromial bursitis in the acute phase should preclude this exercise. Active prepatellar bursitis of the knee is directly aggravated by the kneeling contact position.
