Plank Time by Age: How Long Is a Good Result?

The plank has become increasingly common in gyms and home workouts because it trains the core effectively without requiring any equipment. It is an isometric exercise: the body remains still while the muscles work hard to hold a stable position. The question most people ask is how long they should hold a plank and whether there is a benchmark for each age group. However, correct form always matters more than “breaking a record” for time.

How long is a good plank hold?

Generally, the plank is used as a straightforward way to assess core endurance in healthy people who do not have back pain. For younger adults, holding the position for 45 to 90 seconds is usually considered a positive sign of endurance, while times of 20 to 60 seconds are commonly seen among people aged over 60.

These ranges are only rough guidelines, rather than compulsory targets. Body weight, training background, injuries, breathing control and the type of surface can all significantly affect the result. For this reason, many trainers recommend concentrating on personal progress over several weeks instead.

How can you compare plank time by age safely?

When discussing “plank time by age”, the variation most often considered is the forearm plank. It requires strong involvement from the rectus abdominis, the obliques and the deep muscles that stabilise the spine, making it particularly useful for quick endurance assessments.

To make these comparisons easier, some professionals use time ranges for different age groups among people without relevant medical restrictions. The practical examples below can help you understand your current level and the progress you may be able to make:

• 18 to 39 years: 45 to 90 seconds for the general population; 60 to 120 seconds for those who train regularly.
• 40 to 59 years: 30 to 75 seconds for active people; 45 to 90 seconds for higher fitness levels.
• 60 years or over: 20 to 60 seconds for most people; 30 to 75 seconds for those who follow a regular exercise routine.

How do you perform a plank correctly and avoid back pain?

For the plank to provide genuine benefits, technique needs attention from the outset. The basic position relies on simple alignment: place the elbows beneath the shoulders, rest the forearms on the floor, keep the legs extended and the spine neutral, and press firmly through the toes, with the head following the line of the spine.

1. Lie face down with your forearms supported on the floor.
2. Set your elbows in line with your shoulders.
3. Lift your body, supporting yourself on your forearms and toes.
4. Engage your abdominal muscles, glutes and thighs, keeping your body in a straight line.
5. Breathe continuously without holding your breath until you reach the intended time.

How can you increase plank time gradually and effectively?

To extend your plank time safely, it is helpful to follow a slow, planned progression. A common approach is to begin with sets of 15 to 20 seconds, repeated two or three times, then add 5 to 10 seconds to each set as long as your form remains stable and pain-free.

Adding other core exercises, such as the side plank, bird-dog and dead bug, can help improve endurance and protect the spine. In practice, the plank is usually more effective when it feels challenging but remains controlled. This offers greater benefits than trying to hold it for several minutes with compromised technique and an overloaded spine.
