The workout after the STS leg workout in week one is listed as Strong and Sweaty Bootcamp Premix 1.
Thanks for pointing this workout out, str8shooter. I posted this rotation and I think this is listed incorrectly or I made a mistake when posting it. Day 6 of each week is supposed to be a high impact hiit cardio day. I would not recommend that Bootcamp premix as it uses legs and we wouldn't want to work legs two days in a row. Timesaver Premix 5 from the S&S Bootcamp workout omits legs and so that could be used (adding an ab bonus). Or, you may choose any hiit training workout of your choice. Because I created this rotation a couple of years ago, there are some new hiit workouts that you may want to select for that day - Fit Split Shred Cardio or Fit Split Mixed Impact Cardio for example. Again, I would select the premix with the Bonus Abs segment included so that you are sure to get 2 ab workouts in for the week.
