First of all ignore all the Douche bags on here criticizing whether or not you can bench 245. I went to high school with several wrestlers that were benching in excess of 250 all 4 years of high school. Second, stay away from any test booster or estrogen blocker (MassFx, HyperdrolX2) at age 15. They could seriously stunt your growth and future muscle, strength, size, reproduction ability. Change your routine, if your are more interested in upping your max bench, over gaining size, mass, etc...
try something like this:
Monday; Chest...flat bench, incline, decline, weighted dips, with Tri's
Tuesday; Back...bent over row, deadlifts, lat pulldowns, with Bi's
- you shouldn't do legs the day after back especially if you do heavy deadlifts
Wednesday: Shoulders/Forearms...military sitting and standing, lateral raise, front raise
Thursday: : Legs...squats, leg press, straight legs, power cleans, leg extension
Friday: Chest: Bench Press partial reps in power rack or towel bench press (you roll up a towel place it in the center of your chest and do normal press until bar hits towel then blast up)
Also Google out the PRRS system, Power, Rep, Range Shock system.
Lastly lots of protein for recovery. Good Luck
