    Hi Rumiana,
    I found your workouts on you tube and am just beginning to get into them. I love them, they are a bit tough for now for me.

    The question I had is about your 90 day challenge. I tried to pull up the schedule or the plan from your website but all I get is the videos for exercising.

    Is there something that breaks down the 90 day challenge? What is it, how often do you do it, what is the sequence of exercises, what are the goals? At this point, I feel a bit disorganized with it, just videos that are not connected to each other or a flow. Maybe I missed something.

    Thanks for your help,
