In recent years, the "plank" has become a popular fitness trend, often associated with the idea of an easy and effective way to lose weight. Marketed as "the most practical weight-loss exercise," it promises results in just a few minutes a day. Even well-known figures like real estate tycoon Pan Shiyi have shared their plank achievements on social media. As a result, more and more people are joining the "plank community." But what exactly is a plank, and is it really as effective as it claims to be?
The plank is one of the most common core-strengthening exercises. The basic movement is simple: lie face down, place your forearms on the ground shoulder-width apart, keep your elbows directly under your shoulders, and lift your body so that your upper arms and torso form a 90-degree angle. Keep your toes together to reduce the support area. Your neck should remain straight, eyes looking forward and slightly downward, chest lifted, ensuring that your head, shoulders, hips, and legs all align in a straight line. Your abdominal and pelvic muscles should be engaged, keeping your spine in a natural, physiological curve. Breathe naturally, avoid holding your breath, and make sure your hips don't sag or tilt sideways.
Though it may look simple, the plank engages multiple muscle groups, including the back, abdomen, lower back, glutes, and core muscles such as the adductors and diaphragm. In fact, almost every movement we make—whether eating, walking, or even sneezing—requires core engagement. A strong core not only makes daily activities easier and more efficient but also serves as the foundation for better performance in other physical activities.
However, the claim that doing planks for just a few minutes a day can lead to significant weight loss is somewhat exaggerated. Compared to aerobic exercises like running or brisk walking, the calorie burn from planks is relatively low. To effectively burn fat, long-term aerobic activity combined with reduced caloric intake is more effective. There's no scientific evidence supporting the idea of spot reduction through localized exercises. While planks can help increase your basal metabolic rate, they are best used as an auxiliary tool in a comprehensive weight-loss plan.
Proper form is key when performing planks. Beginners should focus on mastering the technique and start with short holds, gradually increasing time as they build strength. If the body starts to wobble or the form begins to break down, it’s important to stop and rest. Don’t force yourself into a position that feels uncomfortable. Once you get the basics right, you can work up to holding the position for longer periods. It’s also recommended to do 4–6 sets, each lasting 20–30 seconds, with no more than 20 seconds of rest between sets. You don’t need to hold it for very long—most adults who can maintain the position for over a minute are already meeting the standard.
It’s also important to note that many people perform planks incorrectly. Common mistakes include lifting the hips too high or letting them drop, not keeping the upper arms at a vertical angle, tilting the head too far back or forward, or allowing the body to shift sideways. These errors not only reduce the effectiveness of the exercise but can also cause strain on the neck or lower back. Always ensure that your hips, waist, and legs are in a straight line. Before starting, it's a good idea to warm up for 10–15 minutes. For middle-aged or elderly individuals, you can modify the exercise by placing your knees on the ground and bending your calves at a 90-degree angle. Those with conditions like herniated discs should consult a doctor before attempting planks to avoid worsening their condition.
If you're looking to increase the difficulty, you might try the "8-step plank progression." Here's how:
1. Hold the standard plank for 30 seconds.
2. Raise your right hand and stretch it forward for 15 seconds.
3. Switch to your left hand and hold for another 15 seconds.
4. Transition to a double-elbow plank and lift your right leg for 15 seconds.
5. Switch to your left leg and hold for 15 seconds.
6. Lift both legs at the same time, supporting with your right elbow and left leg for 15 seconds.
7. Raise your right hand and left leg, supporting with your left elbow and right leg for 15 seconds.
8. Return to the standard plank and hold for 30 seconds.
This progression helps build strength, stability, and control while making the exercise more challenging and engaging. Whether you're a beginner or an advanced exerciser, the plank remains a valuable tool in your fitness journey—when done correctly.
