first off ditch that routine. A 4-way split is a fairly poor place for a novice to start. You need to start doing the big compound exercises (Squats, Benches, OH presses, Rows, Deads, Chins/Pullups) and doing them often and that means stop thinking in terms of "bodyparts" and start thinking in terms of "lifts".
Stop neglecting your back and legs and start neglecting your arms instead. they are the least of your worries at this time.
I wouldnt bother with that Xplode shit or creatine either, not now anyway. Save your money!
