Haha! You're so very welcome ...I guess lol.@lalalanded @Callan @MomoomoM thank you all! I've been doing Yoga with Adrienne but need something simultaneously a bit more cardio-based and also more focused so I can avoid the lower-back stuff.
Also I really do live for TMI. The cauliflower ear comparison was perfect, thanks MomoomoM. Very...visceral. I had no idea cycling had that sort of effect.
And yes thanks for the recs, people! I'm also going to look up the ballet one.
