Here we go, starting the 5x5 routine because I'm tired of the weak legs. and want a good core! Notes: I spent the last 2 years (off and on) at a gym that only has smith machines and dumbbells. Last time I went I could rep the 80 lb DBs and I squated 125 on the smith machine. Time for a new gym with BarBells! starting stats: 5'7 155 lbs. supplements: None. Protein shakes give me diarrhea.
