I have a question also.
Today I did the second workout with the 20 min cardio then 3 x 10 of everything. This took forever, so I ma curious if I am doing it correctly? especially when it goes to 4 sets soon. I curious about the numbering. 40 stepups for 3 sets takes a while, then side steps, down steps...
Also should you do 3 sets of squats then move onto 3 sets of step ups or do you do one set of everything then repeat 3 times? like a circuit?
