What Is a Yoga Block For?

A yoga block is a firm foam or cork brick that, as teachers often say, brings the floor closer to you. Its job is to support your hand, foot, hip or head in poses where you cannot yet reach comfortably, so you keep good alignment instead of straining or collapsing the shape to make contact.

Watch: Sanjana Prasad's ways to use a yoga block

In the video above, Sanjana Prasad shows that a block isn't only a beginner's crutch. Depending on how you place it, a block can either ease a pose or intensify it, and she works through several familiar asanas to show both.

• Standing forward fold (Uttanasana / Padahastasana): feet shoulder-width apart with the block in front of your feet. Begin with your hands on your waist and lengthen as you inhale before you fold, so the block meets you at a height you can reach without collapsing the spine.
• Dolphin-style preparation: here the blocks make the work harder. Your feet rest on two blocks behind you with the heels lifted, and your forearms are measured to elbow distance with the fingers interlaced. You move forward on the inhale and lift up on the exhale, five times, then rest in Child's pose.
• Puppy pose: with your hands on blocks, which Sanjana calls "my most favourite way to use it".

Watching the sequence helps with something an article can't easily show: how the height and position of the block change what you feel in a pose. Raising the floor under your hands lets the spine stay long. Lifting the feet onto blocks turns the same prop into a challenge for the shoulders.

If you're new to props, try the forward fold first and notice the difference the block makes to the length of your back. Once that feels familiar, the dolphin and puppy variations show how the same simple brick can become a tool for building strength and opening the upper body, not just for making poses easier.

A clear example is Triangle pose. If your lower hand cannot reach the floor without rounding your spine and caving your chest towards the ground, a block under that hand lets you keep length through both sides of the body and open the chest properly. Placed under the hips in seated poses, a block tilts the pelvis forward so the back can stay tall rather than slumping, which makes forward folds far more effective.

Blocks are among the most useful props precisely because they remove strain. They let you practise a pose correctly at your current range rather than forcing your body into a shape it is not ready for. This is not cheating; it is intelligent practice, and it is exactly how flexibility and strength build safely over time.

The two main materials suit slightly different needs. Cork is firmer, heavier and very stable, which many people prefer for weight-bearing support. Foam is lighter, softer and cheaper, and is gentler under the head or hips in restorative work. A common beginner mistake is skipping the block to look more advanced, then losing the alignment the pose is meant to teach.

The takeaway: reach for a block whenever a pose feels out of reach or makes you round and strain. Two blocks give you the most flexibility, and if you do not own any yet, a sturdy stack of books stands in perfectly well while you decide whether to invest.
