The plank is one of the simplest core exercises: no equipment, a little floor space and good form. The hard part is keeping track of time while your arms shake. A timer that talks to you with sounds and short tips means you can keep your eyes on the floor and your body in a straight line.
This plank timer online works on phones, tablets and laptops. Prop your phone up nearby and let it run.

How to Use the Plank Timer Online
Step 1: Set Your Target Time and Variation
Tap a preset such as 1 Minute or type your own time under Target Plank Time. Choose a Plank Variation, here High Plank (Straight Arm). The display shows Ready to Hold 01:00.
Step 2: Start and Hold the Plank
Press Start Plank. After the 5-second get-ready countdown, the panel switches to Hold the Plank and the time counts down while the progress bar fills. Tips such as “Keep your back perfectly straight!” appear under the timer. Tap Hold / Pause if you need a break.
Step 3: Finish and Reset
When the time runs out you see Workout Complete and Done with a full progress bar. Press Reset to set up your next round or try a different variation.
Good Plank Form
- Place elbows (or hands for a high plank) directly under your shoulders.
- Keep a straight line from head to heels. Do not let the hips sag or pike up.
- Squeeze your glutes and brace your stomach as if expecting a light punch.
- Look at the floor slightly ahead of your hands to keep your neck neutral.
- Breathe steadily. Holding your breath makes the hold harder.
A Simple 4-Week Plank Plan
| Week | Hold time | Rounds | Rest between rounds |
|---|---|---|---|
| 1 | 20 to 30 seconds | 3 | 30 to 60 seconds |
| 2 | 30 to 45 seconds | 3 | 45 seconds |
| 3 | 45 to 60 seconds | 3 | 45 seconds |
| 4 | 60 seconds or longer | 3 | 45 seconds |
Move up only when you can finish every round with good form. Three to four sessions a week is plenty for most people. A shorter hold with perfect form is worth more than a long hold with a sagging back.
Choosing a Variation
- Forearm plank: the classic choice and a good place to start.
- High plank: also works the shoulders and arms, like the top of a push-up.
- Side plank: targets the obliques. Do both sides for the same time.
- Shoulder taps: adds an anti-rotation challenge. Keep the hips still as you tap.
Stop if you feel pain, especially in the lower back. If you have an injury or a health condition, check with a qualified professional before starting a new exercise routine.
