Plank Test: How Long Can You Hold It to Be Stronger Than 90% of People Your Age?
Are you stronger than your peers? It’s a question many of us ask ourselves, especially as we age. While benchmarks in fitness can be motivating at any stage of life, understanding where you stand relative to others in your age group can be particularly reassuring. A simple test – holding a plank – can reveal a surprising amount about your core strength and overall fitness level and offer a tangible way to track progress.
The plank, often touted as a no-nonsense measure of core stability, isn’t just about abdominal muscles. It’s a full-body exercise that demands engagement from your glutes, shoulders, and back, testing your isometric strength – the ability to hold your skeleton in place against gravity. But what constitutes a good plank time, and how does it change as we get older? For adults aged 65 and over, the benchmarks are surprisingly attainable, yet powerfully indicative of long-term health.
Plank Time and Core Strength After 65
According to Joe Ghafari, Certified Personal Trainer and Co-Founder of Visiting Wrld, a premium LGBTQ+ fitness retreat, holding a “rock-solid, no-sagging-back plank” for 30 to 45 seconds already places you above the average person in your age group. Visiting Wrld focuses on blending fitness coaching with travel and community. This isn’t about achieving a six-pack; it’s about maintaining functional strength that supports everyday activities.
Reaching the 45-second mark signifies foundational strength crucial for protecting your spine during routine tasks like bending, lifting, and carrying. But the real distinction comes with extended hold times. If you can maintain a plank for 90 seconds to two minutes, you’re considered to be in the elite category, demonstrating core strength comparable to someone twenty years younger. However, Ghafari emphasizes that quality trumps quantity: “a ‘shaky’ two minutes is worse than a ‘perfect’ 30 seconds. I don’t care about the clock if your form is trash.”

Why Planks Matter as We Age
The plank’s value extends beyond simply testing strength. It’s a diagnostic tool, revealing weaknesses in your form that can indicate underlying issues. A sagging back suggests weak lower abdominal muscles, while neck strain may point to postural imbalances. As we age, maintaining isometric strength – the ability to stabilize muscles without movement – becomes increasingly important for preventing falls and managing back pain.
Planks are a particularly effective way to assess this type of strength because they measure muscle engagement, endurance, and overall structural integrity. This is especially relevant as muscle mass naturally declines with age, a process known as sarcopenia. Topend Sports details a 7-stage abdominal strength test, highlighting the importance of core stability for injury prevention. While the plank isn’t a direct equivalent, it offers a readily accessible and practical way to gauge similar capabilities.
Maintaining core strength isn’t just about aesthetics; it’s about preserving independence and quality of life. A strong core supports proper posture, balance, and movement, enabling you to continue enjoying everyday activities with confidence.
What to do if you struggle with planks: Start with modified versions, such as holding a plank on your knees, or reducing the hold time. Focus on maintaining proper form – a straight line from head to heels – before increasing the duration. Consider incorporating other core-strengthening exercises, like bird-dogs or dead bugs, to build a solid foundation.
Looking ahead: Regular core work, including planks, should be a component of a well-rounded fitness routine for individuals of all ages. Further research into the long-term benefits of core strength training for older adults is ongoing, with a focus on its impact on fall prevention and functional independence. Consulting with a qualified fitness professional can help you develop a personalized plan tailored to your individual needs and abilities.
