A. S. Prilipin suggested that to achieve the proper intensity, one should use the rep/set scheme shown in the table, to ensure the greatest development of speed and strength. He discovered that if 7 or more reps were performed at 70%, the bar speed slowed and power decreased. The same holds true when using 80% or 90%. Once one goes above the rep range shown, the bar slows, which translates to less power. If you do fewer or more lifts than Prilepin suggests will cause a decrease in training effect.

Number of Reps for Percent Training

Percent/Reps per set/Optimal Total/Range
55-65/ 3-6 /24 /18-30
70-75 /3-6 /18 /12-24
80-85/ 2-4 /15 /10-20
90+ /1-2/ 7 /4-10
