I'm happy that both of you 5pugmom and rlw3 are loving JNL
JNL and Body Beast were my 2012 hits
I love Total Body Transformer. Is my favorite from the Core/Cardio workouts. So bad is missing. You all are good with the basic tough. JNL is a circuit training system, but is special. Traditional weight training splits and exercises, but with cardio intervals. Translated to a gym routine like the ones I had seen. You do 3 sets, sprint on the treadmill and continue. I knew it was good. Love this system so much!
