Here's a dumb question...

OK I think what it does is if you take the weight you can lift for 10 reps and put that number in, the calculation will come back with a number that is much higher for your 1 rep max. That is the number you use to see what weight you should use for the other exercises.

Edited - here is a website that can calculate also: http://www.naturalphysiques.com/tools.php?itemid=18
 
Great question! Thank goodness for good old wikipedia;)

This is my understanding, by finding your 1 Rep Max you establish a baseline that is customized to you and your individual strength. It's the starting point for all of your lifts, again, based on your individual muscular strength. Repititions will vary depending on goals (ie. endurance, mass building, strength) I'm eager to read other's understanding of this.

steps in thread and gives Lorrie a nuggy for thinking she has asked a "dumb" question then sashays out of thread....
 
My understanding is the goal is to lift a certain percentage of your 1 RM. The rep range will vary depending on the mesocycle you are in. Some will have higher rep ranges with lighter wts (smaller percentages of 1RM) and others will have lower reps with heavier wts (larger percentage of 1RM) She explains it somewhere what percentage you will be using in each cycle. The goal will also be to increase the percentage over time. I hope I haven't thoroughly confused you!!

I think the reason everyone calculates a 1RM using the weights that you can complete 10 reps with is for safety. You might be able to lift that 1RM once... but it's going to be very heavy for you, and you might injure yourself.
 
yes,
Shannon is correct. A one lift max is the heaviest weight you can lift with good form 1x and some measure it exactly that way, however, the risk of injury is high and to avoid potential injury it can also be calculated based on a set with more reps. This would give you a weight that is a close approximation to your 1 rep max.
A 1 rep max is as others have pointed out one indication of your strength and you use that value to figure out how much weight to use in your workouts typically calculated as a percentage of your 1 rep max..
