@ ava35 - I was wondering the same thing. I'm on my 2nd round of doing I,Bodybuilder until the new HP Mass Program is fully posted. MytchBucanan is right...the principles in IBB are indeed the foundation. I have experienced great gains when following IBB; and I'm looking forward to getting into HP Mass after Phase 5. Personally, I hope they dedicate a section of the site to HP Mass like with IBB. CT keeps great things coming.
