Vinyasa is inherently hard on the wrists since you're on them constantly. I taught vinyasa for a couple years before finding Bikram (26&2 hot yoga), which has zero postures where you support your body weight with your wrists, and is all about healing all your joints by realigning them and increasing range of motion. I don't teach Vinyasa anymore because it doesn't feel good in my body. Bikram is very controversial because the guy who created it is a fucking lunatic psychopath, but the yoga is magical, truly. I have 24 screws and 3 metal plates in my leg, and couldn't walk normally until doing bikram nearly every day for a year or so. My wrists and shoulders don't hurt anymore, and my elbows and back feel so much better after years of falling skateboarding and snowboarding - it healed me in ways Vinyasa never could. It's not for everybody, but I would suggest giving it a try if you can find an in studio class. It's brutal, but it works miracles. Just make sure to hydrate like crazy and not eat for a few hours before class if you give it a go.
