I'm 18 and have been lifting for 2 years and im stuck at 230 pound bench and 300 lb squat...i have been working each muscle hard one time per week and resting 3 days per week, im gaining size, but as my friend puts it, my strength doesnt match my size....can someone help me out or give me in depth tips on how to make a workout where i can keep getting strength gains? I'm 6'4 200 lbs
