I've created a new website getfitright.com

This website aims to provide weight training progress monitoring for the masses.

You enter sets of an exercise as you do them, and it groups them together by exercise session and allows you compare sets of different amounts of weight and reps by using a One Rep Max projection.

For example, if your best set of Bench Press is 200lbs for 10 reps one week, and you do 220lbs for 7 reps the next week, it is difficult to tell whether you have made any progress.

By giving an accurate approximation of your One Rep Max, this is clear. In the first case, you "projected" 266lbs. In the second you have projected 270.82lbs, thus you have gotten almost 5 pounds stronger.

This is not to say that you will then be able to do 270.82lbs on the next set, the same day. Rather, this tells you that if you had attempted to do 1 rep of 270.82lbs it would be the same difficulty as what you did.

Naturally, after doing 1 hard set, you will probably be able to do less with each new set. This is why getfitright.com only considers your best sets for each exercise, each time you go the gym.
