I did Adriene's arms and abs the other day. I don't yet have the core strength for the rolling, most of Erin's core ones do that too. I find the balancing on your toes quite easy, but I used to have bad plantar fasciitis and have done lots of foot exercises, so they've obviously paid off.
spudlet I think it took me 3 years of daily yoga to manage chatarunga and updog properly, but you will get there.
I did Five Parks Rise and Shine again today, I find Eagle pose quite easy, weirdly, and managed holding half moon on a block with no wobbles. I'm off to check out deer pose. One of Erin's deep stretch ones does supported fish with blocks, which I like. It might be the posture one.
