Joanna Soh – Killer Booty Band Bootcamp (40 Minutes Workout!). Join me on my first ever booty band class, conducted by our Fio trainer, Tracy Minnoch! I’ve never worked out with a booty band and I have to say, this workout killed me. I was sore for the next several days but it’s sooooo effective! Since then, I’ve started incorporating booty bands into my routine.
