I have long scorned the pink dumbbell training method, but have i been wrong? Hope not. Anyway, read and judge for yourself.

And the consensus is: keep on with your 60-80% 1RM hypertrophy training and you`ll do just fine. No big news there. But nice to here from the gurus anyway.
One thig to take away is that there is a benefit to lighter or "pump" days, or even weeks. And that even lighter workouts still give you good hypertrophy at least where legtraining is concerned.
