A tiny bit off topic, but while everyone is hyping Manduka (and I 100% agree with the hype), I just discovered they have yoga blocks with a curve on one side to make them ergonomic. I got mine and LOVE them. I have some minor CTS and ulnar neuropathy and can have some pain if I put too much pressure on some parts of my hand, and these are so much better as handheld props than standard blocks- msore comfortable and easier to grip.

(and no, I don’t work for them. Just love the block. Also great to hold during planks and pushups and the like, rather than putting my hands flat on the mat).
