You'll excuse me not knowing the full names of the instructors, they didn't give their last names, nor could I find the credits anywhere, not even at the end of any of the segments. I could not even find info on the yogaworks site.
Patty's teaching style -
She does tell you always when to inhale/exhale which is great, she tells you what areas each pose strengthens, she gives good postural instructions on how to do the poses correctly, but her teaching style & voice is the style of an aerobics or toning gym class. Her voice is not soothing, I believe she doesn't always give the Sanskrit names of the poses, nor uses terms that are more aligned with traditional teaching like Rodney Yee, etc. This style has a more watered-down, Western style which many people do like, but not myself. Adding to that that this is hatha style to the point you will be standing waiting in between each pose while she introduces them & each pose is separate from each other w/o flow except for sun salutations. The ending meditation is as another said, has her speaking about what to visualize with the same no-nonsense voice.
Billy's style -
Unfortunately he only gets 10 min. His style was more traditional in that he had you do chair & then right after go into a standing fwd bend which I always do together even if the instructor does not as it just doesn't feel right unless you do. He does grunt or sighs a few times, but the same as anyone would when feeling & enjoying the energy more better in the body when you feel the stretch. In other words, he does have great body awareness & for me, I am more motivated by someone who is, rather then someone who sees yoga only for muscle building or burning calories. In the short 10 min, he does do a couple sun salutations (quicker, but good instruction then Patty), tree pose, a very modified dancer's pose to the point it's more a quadriceps stretch (but doesn't say it's modified), torso side stretch & not much else since it's only 10 min.
I looked all over & the only clips I could find of Patty & Billy is on "exercise. tv" & in the store area. You can see clips of the other two dvds with Jessy/Jesse
