Knee Plank Hold
Knee Plank Hold is a bodyweight strength exercise targeting the abs. The knee variation reduces load compared to a full plank, making it an effective entry point for building core endurance and learning proper plank alignment.
How to do it
- Begin on all fours and lower your forearms to the floor or keep your arms extended.
- Lower your knees to the floor and align your body from knees to shoulders in a straight line.
- Engage your core and avoid letting your hips sag.
- Hold the position for the desired duration while breathing steadily.
- Rest and repeat as needed.
Form cues
- Keep your body in a straight line from knees to shoulders
- Pull your belly button toward your spine
- Press your forearms firmly into the floor
- Squeeze your glutes to stabilize your hips
- Keep your neck neutral by looking at the floor
Breathing: Breathe steadily throughout the hold; do not hold your breath, as this increases internal pressure.
Common mistakes
- Sagging hips, which puts unnecessary strain on your lower back
- Holding your breath, which prevents proper core engagement
- Shrugging your shoulders toward your ears, which creates neck tension
- Looking forward instead of down, which misaligns your cervical spine

Where should I feel this exercise?
You should feel tension in your abdominal muscles. If you feel it primarily in your lower back, your core may be fatigued or your hips may be sagging.
What if my arms start shaking?
Shaking is a normal response as your muscles fatigue. If your form breaks down, rest and try again with better alignment.
Can I do this every day?
Yes, core endurance training can be performed frequently, provided you allow for recovery if you feel significant muscle soreness.
