View Full Version : 1rm != 1rm
09-26-2011, 04:46 PM
This past weekend I did some 1RM testing for the IronStrong PowerLifting Event (http://ironstrong.org/index.php/forum/47-our-first-powerlifting-event/). It was a lot of fun and I'm still sore, but I noticed something odd when I entered my stats for the day.
I entered my first squat attempt 1RM at 315. The app responded and congratulated me on a calculated 1RM somewhere around 328 or something like that. That seemed rather silly to me.
If I do 1 rep in a set and it is higher than any other effort I've done, wouldn't that by definition be my 1RM?
The same thing happened for every other lift I did (squat, bench press, and deadlifts).

I noticed the exact same thing. You would think if you truly did 1 rep of something that it would register it as your 1 RM; not add additional weight. If I could have lifted that additional weight than I would have recorded it as such; and that isn't the case and I could only wish I could lift that much more.

Here is what I noticed. If I do 3 sets of Pull Ups with 6 six reps at a weight of 165lbs, the RM equals 198. 165 is 83.33% of 198. The 83.33% is the same no matter what exercise I do as long I as use 6 reps per set. It sounds like a Jefit algorithm, for what I am not sure. I thought you only had to be at 75% of your 1RM max to produce testosterone.

It's a calculation; not an exact measurement.

But what does it mean?

But what does it mean?
Theoretical amount you could lift one time. Not much use if you're truly lifting your 1RM and record it.

Surely this depends? 1RM should be the MAXIMUM amount you can lift for one rep. If your routine has you ending with a single rep of a heavy weight after, for example, pyramiding sets, then the amount you lift for one rep will be LESS than your 1RM (which is what you would have been able to lift if it had been your first and only rep).
Just being devils advocate here...

In my case I was testing what my actual 1RM was. Problem is when you enter a weight, and put 1 rep, the app does a bogus calculation yielding a higher number. The weight I entered was a true PR (personal record) for me. I couldn't add additional weight if I wanted.
In short, when a user enters a 1 RM lift and it happens to be the max--use that weight, not a calculation.
