I love Casey Ho's videos too! She's great and I can see the results in my strength as well as in the mirror. I've been doing them for about one month on and off.
I love that I can mix and match her videos and work on the body parts I want for the day.
I'm jealous of how she can effortlessly carry on a one sided conversation while I'm hurting and puffing for air! Lol. Even during the cardio videos!!!
