Yoga Pose Rivals Sit-Ups for Core Strength, Experts Say
The scent of old newsprint still clings to my memory, a lingering echo from early days at Reuters. It wasn't the breaking headlines that captivated me, though; it was the meticulous dissection of a story, the patient unpicking of layers.
Boat Pose vs. Sit-Ups: A Stronger Core?
Jump to: What is the best move for abs? Is it really better than 100 sit-ups? What does a PT have to say about all this? How to do boat pose There are few exercises more synonymous with getting abs than the humble sit-up – but, according to some experts, you might be better off swapping your sit-ups for an easy yoga pose instead.
A widely repeated claim in the yoga community suggests that practising boat pose (navasana) can rival the effects of doing 100 sit-ups. While that comparison isn't backed by robust scientific research, those in the know say the pose can be an incredibly effective way to build core strength because it trains far more than your abdominal muscles alone. Unlike sit-ups, which involve repeatedly bending the spine, boat pose is an isometric exercise, meaning you hold one position under tension. That forces multiple muscle groups to work together to keep your body stable.
Why Boat Pose Works
Melissa Leach, a yoga instructor and strength and conditioning expert at Yoga-Go, explains, “Boat pose is one of the most efficient core exercises because it doesn't just isolate the abs, it engages the hip flexors, glutes, pelvic muscles, and back all at once, helping build functional core strength rather than working one single muscle in isolation.” She adds that the exercise develops stability as well as strength. “Boat pose also helps build stability rather than just endurance. Holding the position forces your deep core muscles, the ones that support your spine and pelvis, to switch on and stay engaged throughout. Over time, this can translate into better posture, a stronger lower back, and a core that supports your everyday movement.”
A More Challenging Alternative
Daniel de la Hoz demonstrates boat pose. “This is part of why it can outperform traditional exercises like sit-ups, as they target a much narrower range of muscles. A sit-up is a repetitive, single-plane movement, whereas boat pose asks your entire core to work together to keep you balanced and lifted, which is a much greater test of strength and control.” Leach notes that boat pose can be a gentler alternative to traditional sit-ups for some people, as it builds core strength through controlled, isometric engagement rather than repeated spinal flexion. “The traditional version can be challenging for beginners, which is why modified variations are a useful way to build strength, confidence and technique before progressing over time.”
What a Personal Trainer Says
Jessica Robinson, a Level 3 Personal Trainer and ambassador for Mirafit, says the answer depends on your goals. “The boat pose and sit-up are both effective core exercises, but they serve very different purposes and should be used at different stages of training,” she explains. She says boat pose develops core stability by teaching you to brace your trunk while maintaining a neutral spine, whereas sit-ups strengthen the muscles responsible for bending the spine through movement. “The ‘100 sit-ups’ comparison is a well-known reference in the yoga community, often used to highlight how challenging and effective boat pose can be when practised traditionally — typically held for 25 breaths, broken into five sets — rather than a literal, like-for-like measurement.”
