NROL4W, Afterburn and Warp Speed Fat Loss are all programs by Alwyn Cosgrove. Google him. There's tons of info on the web! Here's a very brief description of the programs:
NROL4W is focused on gaining strength and building muscle.
Afterburn is focused on fat loss.
Warp Speed Fat Loss is like Afterburn after drinking 13 pots of coffee! LOL
Alwyn believes in interval training as opposed to steady state so all of the cardio prescribed for his program is just that. The weightlifting done focuses on working multiple muscle groups at the same time in every exercise so you will not find exercises like tricep kickbacks in his work outs.
TT is Turbulence Training: check it out on the web as I don't personally know much about it. Maybe someone else will chime in on it though.
One more thing: All of Alwyn's programs are either downloaded to your computer as an e-book or you can also order the hardcopy book but they are not DVD work outs.
TT is a subscription I believe where you get online access to written rotations to follow. I was recently on the TT site though and saw that they also have a DVD set available.
HTH a bit!
