You should be following basics:

• Spend the majority of your program not reaching absolute fatigue in a set and not failing a rep 

• Program effectively in the 60-80% of your 1RM

• Split your program in to either high volume/low intensity or low volume/high intensity and switch between these two every 8-12 weeks

• Make small increases to your intensity OR volume each week (E.g 5% increase in weight week to week)
