i did DC training as a natural, it was OK but my joints didn't particularly like it even with the higher rep RP. extreme stretching didn't do much for me
the thing i don't like about it is being tied down to a routine, nowadays i train by feel and what i feel like doing that day, sometimes i take 2 days off and sometimes i take 1 day off, sometimes i go 1 on 1 off, or 2 on 1 off, or what have you. i think training by instinct and response by how you feel like you recover, both your CNS and your muscles, is crucial to take you to an advanced level with your physique
