I’m gonna struggle to control myself from trying out all the workouts during this weekend. Whooooieee. I also bought a new weighted jump rope yesterday. I love jump rope, could you girls maybe do some cardio routines (or Chyna’s kickboxing) and include the jump rope? Just like the booty bands it’s a awesome “piece of equipment” that does wonders & barely takes up space. 😘

          1. Eeek, I can’t wait either. 😍🤩
