    Awesome upper body day with Danielle. Still wish they did more ab specific work on upper body days (kind of incorporated with the plank stuff), but otherwise awesome.

    Power Hour (Total Body)

    Great class! The only suggestion I’d have - the instructor started going over what we’d be doing in class while we were still warming up. Her voice is on the softer side so it was hard to concentrate on what she was saying and do jumping jacks.

    I found the resistance and RPMs that Jason suggested to be incredibly unrealistic. But that being said, I got my second best score of all time, so maybe that was motivating?! Good mix of time sitting in the saddle and in 3rd position, as well as hills and sprints. I'll be back for another of Jason's classes.

    Challenging. Just what I needed. Amy really pushed me. Also, Amy was excellent in the fact that she treated the group equal though she knew obviously knew others. She grouped her comments like “way to go GUYS, looking good! You are doing great. LET’S keep it up and push!” This, to me expresses a knowledgeable and aware instructor. This “team talk” sort of approach is sure to encourage everyone as a whole and that is cool. I think calling out people you know and commenting on their form individually and how well they are doing without doing it equally for everyone else is no good. Way to go Amy. Great energy.
