Quick Answer
Yoga blocks bring the floor closer to you, allowing proper alignment in postures that would otherwise require flexibility you have not yet developed. Use them under the hands in standing poses, under the hips in seated poses, and under the chest or sacrum in restorative postures. Blocks are for every level, not just beginners.
Yoga blocks are one of the most underused and most misunderstood props in yoga. Many practitioners avoid them because they feel like an admission of limitation. The opposite is true: using a block intelligently is a sign of body awareness, not a lack of it. Blocks allow you to practise postures with the correct alignment and depth at your current level, which is always more beneficial than forcing a shape that sacrifices form.
How Blocks Support Alignment
The primary function of a yoga block is to bring the floor closer to your hands. In Triangle Pose, for example, placing a block under the lower hand allows you to maintain a long, open spine and full chest rotation rather than collapsing the torso forward to reach the floor. The pose works at its intended depth regardless of your hamstring flexibility. In Half Moon, the block under the bottom hand creates the stable foundation that allows the hip stack and arm reach to happen properly.
In seated postures, a block placed flat under the sitting bones tilts the pelvis forward and relieves compression in the lower back. This small adjustment transforms postures like Staff Pose and seated forward folds from an uncomfortable strain into something genuinely accessible and productive.
Restorative and Yin Uses
In restorative and Yin practices, blocks placed under the chest, sacrum, or inner thighs create passive support during long holds. In Supported Bridge, a block under the sacrum allows the lower back to release completely without any muscular effort. In Reclined Butterfly, blocks under both knees create the supported opening that lets the inner groins release over time rather than straining to hold the position.
Getting Started with Blocks
Most blocks have three height settings: high (the block standing on its short end), medium (on its long side edge), and low (lying flat). Begin at the highest setting and work down as your flexibility develops. Start with just one block in a standing forward fold: place it at its highest height under each hand and notice how this changes the quality of your breath and the length of your spine.
Cork blocks offer a firmer, more stable surface and are the sustainable choice. Foam blocks are lighter, more forgiving in restorative work, and better for beginners who may need softer support. Having at least two blocks at home expands what is possible considerably, as many restorative setups use two simultaneously.
Frequently Asked Questions
Are yoga blocks necessary for beginners?
Not essential but highly valuable. One or two blocks make many foundational postures significantly more accessible for beginners, and using them properly from the start develops good alignment habits that benefit practice for years. The small cost is among the best investments a new practitioner can make.
What is the difference between cork and foam yoga blocks?
Cork blocks are firmer, heavier, and more stable, making them better for standing poses where you need solid support. Foam blocks are lighter and softer, making them more comfortable for restorative postures and more portable. Cork is the more sustainable choice and tends to last longer. For most practitioners, cork is the better investment.
How many yoga blocks do I need?
Two blocks cover the widest range of uses. Many restorative and Yin setups require two simultaneously, under both knees, both hands, or stacked for greater height. One block is useful and a fine starting point, but two significantly expand what is accessible in your practice.
Can advanced yoga practitioners use blocks?
Absolutely, and many do regularly. Advanced practitioners use blocks to deepen poses beyond their natural range (blocks under the hands to go deeper than the floor in forward folds), to explore alignment in new ways, and in restorative sessions for supported passive opening. Blocks are tools for any level.
What height should I use a yoga block?
Start at the highest setting and reduce as flexibility improves. In standing poses, the goal is to use the lowest height at which you can maintain proper alignment (long spine, open chest, steady breath). In restorative postures, choose the height that allows complete release without any sensation of strain.
Can I use a book instead of a yoga block?
A thick, firm book or a stack of books can substitute in many situations, but the stability is less reliable than a proper block. For restorative postures and seated work, the substitution works reasonably well. For standing postures where the "block" takes significant bodyweight, a proper block is safer and more practical.
