I've heard this as the standard for Keifer now on CBL, but I don't understand why… I'm doing the mi40x2 program from PBAK, and his protocol calls for a PWO shake within 15 minutes of your final rep. I've tried both and noticed I feel much less sore the fast I take in the PWO, but have switched back to the 1 hour wait for my PWO shake then another hour for my PWO MEAL/Backload. I'm just curious what the rationale is behind this. I haven't found much clarity on this from the podcasts I've checked out. Could someone possibly clarify the "why" on this for me?
