We are talking about two different things based on that post. I am not sure what you are referring to when you mention both heavy weight and high intensity, but it scares me to think you could be referring to crossfit type workouts.
DC training would be heavy weight and high intensity and is nothing like crossfit
Ahh, yes. The old doggcrapp training. I know a several guys that were training to be BBs that liked that.
My fault 6andaHalf, I was not referring to this, but rather a variation of HIIT with med weight and high volume.
