How long should you hold a plank?
Published 30 September 2026 by TRACK AI Coach
The plank is a simple test: hold your body in a straight line and don’t let it sag. It trains your core to resist movement, which is what it does when you carry shopping, lift a box or hold your position in a push-up. So how long should you hold it? The honest answer: only as long as your form holds.
The short answer
For most people, 2 to 4 holds of 20 to 60 seconds with good form are more useful than one long, shaky hold. Once you can hold a clean plank for about a minute, make it harder instead of longer.
Why longer isn’t always better
In a long hold, the last part is often the worst part: your hips sag, your lower back takes the strain and your shoulders creep up towards your ears. Those seconds count on a stopwatch, but they don’t train the position you’re after. Several shorter holds with rests in between let you spend more total time in good form.
Good plank form
- Elbows under your shoulders (forearm plank) or hands under your shoulders (high plank).
- A straight line from your head through your shoulders, hips and knees to your heels.
- Glutes squeezed, stomach tight, ribs pulled down.
- Head in line with your spine, eyes on the floor just in front of your hands.
- Steady breathing. If you have to hold your breath, the hold is too hard for now.
How long at each level
- Just starting: 3 holds of 10 to 20 seconds, knees down if needed.
- Getting there: 3 holds of 20 to 40 seconds on your toes.
- Comfortable: 3 holds of 45 to 60 seconds, then move on to a harder variation.
Make it harder, not longer
- Squeeze harder. Pull your elbows towards your toes and squeeze your glutes as hard as you can for 10 seconds. It’s surprisingly tough.
- Lift a foot. Raise one foot a few centimetres for a few seconds, then switch, keeping your hips level.
- Shoulder taps. In a high plank, tap each shoulder in turn without letting your hips rock.
- Side plank. Train the sides of your core, knees down or feet stacked.
- Feet raised. Put your feet on a step to shift more of your weight onto your arms.
Common mistakes
- Hips sagging as your core tires. End the hold, or drop to your knees for the last few seconds.
- Hips too high, which makes the plank easier by taking weight off your core.
- Head dropping, with your eyes on your feet. Look at the floor just in front of your hands.
- Watching the clock. Set a target, but stop when your form breaks.
What the coach checks
With your phone on the floor to your side, the TRACK AI coach calls out “Hips sagging”, “Hips too high” and “Head dropping”. Its timer pauses while your hips sag and carries on when you lift them back into line, and your score for the hold is the share of it you spent without that major fault.
