I did the first workout on 30 Minutes - Back/Legs/Chest. I did just the weights portion, but there are premixes that offer intervals of active rest (step touches on the floor, etc) and core work.
I used 12 lb. dumbbells throughout because I wasn't sure what I was getting myself into
. Kelly says advanced should use 15 and 10. Sometimes she adds a twist to the moves but the modifier in the back usually does things straight up, and Kelly always mentions to do what's comfortable for YOU.
This is a short workout that packs a punch if you heavy up - next time I plan to use 15s in this one. She does circuits of back/legs/chest - whatever rest period you want - and then repeats. Then she moves onto another circuit for those body parts. Chest work is pushup variations.
I know there was some criticism of not having legs on its own. All I can say is if KCM ever puts out a 30 minute leg workout it will surely kill me. There were some nice moves with one legged squats that I definitely felt. Once I strung together the leg work from two different KCM sculpting tapes and it was awesome. Maybe she'll do a killer standalone leg workout someday.
