some programs say just by contracting your targeted muscles in a fixed position that they can grow! What do you think?

Yeah I have heard of this device just called the Bully Xtreme where its this small workout equipment you can carry anywhere. Even though it weighs 5 pounds, it has resistance from 10-600lbs and its meant for isometrics. You should check it out.
