A question for those who saw Muscle & Fitness DVD

[Shaga]

Hi, i saw yesterday the Muscle & Fitness DVD for Back & Legs

I have small question, they have 2 programs

Mass-Gaining Routine
Muscle-Defining Routine

Can i do both of the 2 routines in the same training day or it will put a lot of stress of the muscles?

Mass-Gaining or Muscle-Defining Routine or both?

Use exercises from both lists, bot ignore the rep system from the second list and keep it in a 8-12 range.
