Hugger Mugger 5 in. Big Foam Yoga Block - Extra Large Size, Dense Foam, Reliable Support, Beveled Edges for Comfort, Great if You're Taller or Less Flexible

The blocks provide a more stable basis for ham string stretches, compared to a stack of two to three standard blocks. Also provides a higher position when sitting on the floor.

This block could not be better! It is solid, doesn't slip, and its surface is comfortable, with no sharp corners.

I use this daily for pelvic lists and other exercises. It is quite strong - I weigh about 300 lbs and it always feels quite stable and firm. It’s also nice and large: I have fairly big feet and couldn’t fit my whole foot on a standard yoga block. This one has plenty of room. I liked it so much I bought a 2nd one to keep at work!

The larger block size is great if you can't reach far enough when you bend over. It also provides a larger surface to sit on. But be aware that the larger size also requires a large hand to be able to grip around the block. So if you have smaller hands, this may not be the block for you.

I love these blocks. I don't use them for yoga, instead, I use them for deep squats, KB hinges and butt workouts. It's perfect in shape, density, size and stability.
