So, what is the purpose of this article?

Many exercise websites have info on the 10 rep maximum and down to 2 rep max.
However, that can be quite stressful and painful for many people aged over 40, or those
who are recovering from joint injuries, rotator cuff problems and so on.

I have researched the logs and blogs of dozens of athletes, then 
carefully documented my own training as well. I found that the average number of reps
to be done with a weight for any exercise to be able to do double that weight is 24.

Yes, it never fails, as long as the gap between a rep is kept to one second.

So if you can squat 24 reps with a 100 pound barbell, your best will be 200 pounds.

If you bench press 48 reps with a 60 pound barbell, your best will be 180 pounds.

This knowledge allows us to increase strength and power by using lighter weights.

Injuries are banished.

Try it and see, just increasing your 24 rep max is bound to make you stronger. 
It is great for the heart as well due to the aerobic element involved with more reps.
