G-Force,
1st off you need a day or 2 off so your muscles can heal. i would space out your tri and shoulder workout because your using triceps with shoulders chest and obviously triceps.
>>what works for someone doesn't work for everyone. from what ive seen/learned and done, the best way to jumpstart your legs is to do around 20 reps for each set for about 2 weeks. As for your chest, try mixing up your routine every time, (ie barbell bench dumbell bench smith machine bench, barbell incline . . . etc)this will keep your body guessing and should stimulate growth, (aslo mix it up with cables, flyes, dips etc) try not do to the same workout 2x in a row. A possible schedule could be
1.legs
2.chest/shoulders
3.back/bis
4.off
5.legs
6.chest/tris
7.off
>>as far as the theory goes, imo it is false. the longer you work out the more fatigued your muscles become and after you work out for longer then 1.5hrs your testosterone levels begin to fall.
goodluck bro!
