คำถามที่พบบ่อย

What is the plank test?

The plank test measures core endurance by how long you can hold a proper plank position. You enter your hold time, and the calculator rates your core strength and shows where you stand against typical benchmarks.

How do I perform the plank test correctly?

Hold a forearm plank with a straight line from head to heels, keeping your core braced and hips level. Time yourself until form breaks, then enter that duration. Stop early if your lower back sags rather than pushing through poor form.

What is a good plank hold time?

Holding a plank for about 1 to 2 minutes is a solid result for most adults, while beginners often manage 20 to 60 seconds. Times well beyond 2 minutes indicate excellent core endurance, though quality of form matters more than chasing a number.
