Powerblocks rock. Not an expert,but that does seem a bit lite in the intake department,(considering the energy output there). May want to add something else with that protein shake after the diet,and maybe a bit more before the workout. Could be just the portions you're eating are a little small. Some good recommendations on the net about diets with P90X.
Just got back from the gym. Bit crowded tonight,but managed to bit and piece the work out to completion.
Heavy day today. 3 sets of 4-6. Lateral Raises,Bench Press,Lat-Pulldowns,(with a closer grip),Front Military Presses,Shrugs,Squats,DB bent legged deadlifts,and calf raises.
I'll hit arms the next time in.
