Set the timer to 17 seconds

Online timer for 17 seconds

Holding a steady plank while keeping track of form makes every moment feel occupied, so let a seventeen-second countdown handle the timing. Set the phone where its screen stays visible without turning your neck, then settle your gaze on one fixed spot near it. That leaves your attention on even breathing and a level back rather than mentally counting.

As your forearms return to the mat for another plank, repeated countdowns can give the end of a home workout a clean rhythm. Let each alert mark the release, reset the countdown during the short recovery, and begin again only when your elbows and feet are set. Using the same interval for several rounds also makes it easier to notice when your position changes instead of guessing how long each hold lasted.

With your eyes on the floor and your effort on the final hold, the finish needs to stand out from a pedestal fan, children talking, or a tradie working next door. A clear alert at moderate volume, placed close to the mat, is more useful than a loud phone across the room. If headphones are already part of the workout, use a brief tone that can be heard without masking everything around you.
