Too complicated. When it doesn't work for you he can say "Well, you didn't do what I said".
That's pretty accurate.
I tried DC training for a short period of time, it was way too hard on my joints.
My friend up in New York did DC training for a while and got a bit stronger, but like most other people he got burned out on it.
I always thought it was a gimmick; Dante is a smart guy but i never really got why DC was so popular for a few years. He made a lot of money off supplements too.
