starting PIYO

I have about 20lbs to lose. I hate high impact but love yoga so I'm hoping this can help me get closer to my goal. I'm horrible at sticking with something like this past two weeks. Beachbody assigned me a coach, but she's 19! I'm almost 35 and I have had 3 kids, 2 C-sections, and 1 tubal surgery. I'd much prefer a coach closer to my age who understands that the body is vastly different at 35 than 19. Any idea how to get assigned a different coach? Anyone here a coach? I'd really like to make this goal of mine, finish 60 days and jump start a new body for myself. Support appreciated
