Say you can do 12 reps with that 100 lbs, enter 100 in multi rep poundage then enter 12 in # Reps with this weight Then click on Submit Calculation. Your 1Rep Max should be 139, That would be your 1 Rep Max for the Bench Press then use a calculator for the % to use for each set. You will find that this is so accurate that if the set calls for 10 reps you will not be able to do the 11th rep. As your strength increases and you can do more then 3 extra reps then is called for its time to recalculate your 1Rep Max. The best thing to do is to re calculate about every 4 to 6 weeks.
