How long have you been training DC for, what sort of gains?
What sort of time under tension does DC reccomend you should shoot for. Ive seen some guys doing sets with over 10 reps, sometimes up to 15 for legs. and DC reccomends 8 second negatives? that would be about 150 seconds (8 seconds down, 2 up, over 15 reps) TUT? is that right?
what time should you be shooting for each set, before you go into your static hold?
