You might already be embracing smarter, more strategic workouts—swapping long, unfocused gym sessions for shorter, more efficient ones or choosing active recovery over constant high-intensity routines. That’s great progress. But when it comes to planks, holding them for minutes at a time may not be as effective as you think. In fact, less time might mean more benefit when performing this core-strengthening staple.Look around any gym, and you’ll see a mix of plank durations—some people powering through marathon holds, others keeping it brief. If you find yourself wondering how long you should hold a plank, know that there’s no one-size-fits-all answer. Everyone’s body, goals, and fitness levels are different. The real question isn’t about how long the average plank should be—it’s about what duration delivers the best results.While time under tension is often linked with muscle growth, anything beyond two minutes in a plank might be ineffective—or even counterproductive. “Enough is enough,” says Dan John, author of Can You Go? and contributor to Men’s Health. “It’s just a plank. More is not better.”So what’s the sweet spot for plank duration? According to Kevin Carr, CFSC and co-founder of Movement As Medicine, beginners and seasoned exercisers alike should aim to hold a front plank for up to a minute—maximum. Going beyond that can cause form to break down and increase the risk of lower back pain. Plus, planks aren’t exactly functional in daily life, so holding them forever doesn't yield much real-world benefit.Carr explains that the plank is excellent for building intra-abdominal pressure and strengthening the anterior core muscles like the obliques and rectus abdominis. But to reap those benefits, you need quality over quantity. If you’re doing it right—bracing your core, glutes, and spine—it’ll feel intense quickly, and you may not last more than 20 to 30 seconds at first.Before attempting advanced variations, ensure your form is spot on. A passive, sagging plank isn’t doing your core any favors. Instead, actively engage the abs, glutes, and adductors, and keep breathing steadily to maintain full-body tension. If tension fades before your timer runs out, stop—good form matters more than reaching a time goal.Once you’ve mastered the basic plank, it’s time to explore more dynamic challenges. Try these expert-recommended variations to activate different muscles and improve core control:Plank Shoulder Taps: In a high plank, alternate tapping each shoulder with the opposite hand while keeping hips steady. Aim for 8–10 taps per arm.Bear Plank: From all fours, lift your knees an inch off the ground and hold, engaging your core and lats. Start with 30-second holds.Plank with Leg Lifts: In a forearm plank, lift one leg at a time a few inches off the floor without letting your hips rotate. Hold each lift for a second or two.Ultimately, planks are a powerful tool when done correctly. Focus on proper alignment and controlled breathing to truly strengthen your core—and forget about holding on forever.
