Agreed. Consistency isn't only important in relation to getting in the weight room, but also what is done... lifts, reps, sets, technique, order of movements, etc. You take a person who is used to squatting sets of 5 and get him doing sets of 8-12, hes going to suck at first. When I switched from a upper/lower 4x week system to a full body 3x week system, I wasn't used to squatting and THEN pressing and THEN pulling. For a year and half I became accustom to doing 1 of those with the same effort that I'm now doing all three. When you make changes you have to be consistent for sometime or you'll never adapt.
