Training to failure at a high intensity is the Arthur Jones way.

But it should also be mentioned while Sergio (admittedly used 'roids) and Casey Viator (natural!) were friggin huge, they only trained twice a week AT BEST. After they got big, it became 2 times in 10 days.

Also, you may want to look into Rice Protein. Tastes bad, but may have to be your supplement.
