Just found this one, don't know if it has been posted yet??

good calculator

**dougnukem** · 12-01-2005, 05:23 PM

Interesting to know.

**shiznit2169** · 12-01-2005, 06:18 PM

it's not really that accurate

For deadlifts, i can only do 315 for 3 reps and it says my 1RM is 351..

which is totally wrong because my 1RM is 380

**P-funk** · 12-01-2005, 06:26 PM

no RM calculator will ever be 100% also, you have to think that things like rest pause sets etc...will throw it off. and with the deadlift, you may pull 315 for 3 solid reps and put it in there and get a 1RM of 335. But with shit fuck form you may be able to pull 400 off the floor. So it is a little off with things like that.

I wonder what they use to figure these out. So many people are so different because they're more or less efficient in different rep ranges.

**dougnukem** · 12-01-2005, 06:28 PM

Nobody said it was flawless.

yes, shit fuck form is one of my favs. It is up there with "shit bag genetics"........for example "God, that guy is really skinny fat and sloppy."...."I know, he really has some shit bag genetics!".

what they use is a guess that 100% is your 1rep max and every 5% lower then that your rep maximum will fall by 2 reps...

so

1 rep = 100%
2 reps = 95%
4 = 90
6 = 85
8 = 80
10 = 75

probably some sort of study(ies) or research done long ago which helped come to the conclusion but I don't know for sure.

Another good one. Thanks!

no problem and yes, "shit bag genetics" is a medical term in case you were wondering.

those calcs r shitty, i train at real low reps but wit relativily high weights. So my body is traind alot more explosivly and not for stamina. i doubt i can throw up 200 8 times but i have thrown 310 before(speaking on bb flat bench). I dont think they really should be used at all

the further you go from the 1RM the less accurate it is (ie your 2RM percentage is more accurate then your 12RM percentage). Also, again you have to remeber that rep quality and rep tempo must remain constant when testing a reps maximum. And ofcourse, if you don't train in a higher rep range then you wont be strong in that rep range (relatively speaking). However, if you trian in a low rep range you will be stronger in that rep range then if all you did was train in a higher rep range. That was the problem that a lot of people ran into with linear periodization...there wasn't as much carry over from one phase of training to the next. that is why most look to conjugate or concurrent training (undulating periodization).

These calculators are typically made by combining a ton of data from a ton of different lifts. Statistically, it would be smarter to have a separate calculator for each lift.

**Squaggleboggin** · 12-01-2005, 07:16 PM

I believe in this one you can choose deadlift, squat or bench.

**Dale Mabry** · 12-01-2005, 07:16 PM

BTW, all this calculator does is find the 1rm for each rep range and averages it out from the same set of data.

You probably don't push yourself enough on your reps and training. So when you max you are for the first time giving 100%, you might want to apply my wisdom to your next workout.

Don't tell me that i "probably don't push myself enough on my reps and training". How the fuck would you know how i train? You have no idea so take my advice and shut the fuck up.

Also, after reading p-funk's post there are too many variables that contribute to the percentages so i agree with him.

**BigDyl** · 12-01-2005, 09:54 PM

It's wrong!

Said I could DL 450. I can only DL 445.

You were supposed to enter the weight in pounds, not grams. I guess in your case it is pound.

Damn man, he was only saying you can prolly do more during ur regular workouts than ur giving urself credit...I get what he's saying....there's been sets where I would put on more weight...and just breathe better and get my mind right before the set...and do more reps than with lower weight...

I'll tell you what, you keep your big stupid mouth shut on my threads and I will promise not to give you any more training tips you lazy fuck.

I feel the love in this thread. Someone posts a tool to aid you in your workouts. Another person calls it crap. First said person expresses his observation in second person's ability to push his personal threshold, but doing so in a manner that offends the fragile ego of second person. Second person proceeds to blow a gasket, thus proving how fragile of an ego he truly has, unable to except some simple constructive criticism. First person counters with an offensive of his own. Moral of the story:
Posting in threads can be hazardous to your health.
