kpat102 Posted April 22, 2014 Report Share Posted April 22, 2014 Hey lads,Anyone know of a chart that can be used to predict a 1RM based off of anywhere between 5-15 reps? Its for a uni project im doing, I have a bunch of numbers of peoples RMs that range from 5-15..goal is to find out their 1RM. Thanks a bunch Quote Link to comment Share on other sites More sharing options...
jimmybro1 Posted April 22, 2014 Report Share Posted April 22, 2014 Plenty of calculators online. Just throw some random numbers and reps in and plot it on a graph and you will have the function they use. Quote Link to comment Share on other sites More sharing options...
kpat102 Posted April 22, 2014 Author Report Share Posted April 22, 2014 yeah i need a specific chart so i can use it as a reference tool etc, uni are nazi cunts about it! Quote Link to comment Share on other sites More sharing options...

Its for a uni project im doing, I have a bunch of numbers of peoples RMs that range from 5-15..goal is to find out their 1RM. Thanks a bunchThey aren't very accurate. And I don't see what the point of them is... Who's to say if you can do 15 reps of X you should be able to do 3 reps of Y... It's about as unscientific as you could get. It all depends on how you train. So so assuming everything is equal apart from our training. If you train in 12-15 rep ranges and I train in a 3-6 rep range.your 15 RM weight equals my 3 RM weight and vice versa according to this calculator. I can assure you that isn't going to be true. if you train at higher reps, you will be better at higher reps. If you train at lower reps you will be better at lower reps.If you wanna know your 1RM then do your 1RM, don't use some calculator and think that's your max.

Its just an estimation anyway. Quote Link to comment Share on other sites More sharing options...
kpat102 Posted April 22, 2014 Author Report Share Posted April 22, 2014 yeah man agreed completely. i think theyre ridiculous as well, but i need it for an assignment - i dont make the rules hahah just need to get this shit done! Quote Link to comment Share on other sites More sharing options...

Leeroid Posted April 22, 2014 Report Share Posted April 22, 2014 You can find the formulas they use for the various 1RM estimators online. I find them to be pretty accurate up to the 5 rep range mark. At the 8 rep mark, they'll start to overestimate my 1RM because I train for strength and suck at rep work. But I think it's reasonably accurate for most people. Quote Link to comment Share on other sites More sharing options...

Leeroid Posted April 22, 2014 Report Share Posted April 22, 2014 Anything above 10RM tends to be too inaccurate which is why they don't have it. These formulas have been tested to be accurate to within 5% of actual 1RMBrzycki: 1RM = W x (36 / (37 - R))Epley: 1RM = W x (1 + 0.0333 x R)Lander: 1RM = (100 x W) / (101.3 - 2.67123 x R)Lombardi: 1RM = W x R0.1Mayhew et al.: 1RM = (100 x W) / (52.2 + (41.9 x e-0.055 x R))O'Conner et al.: 1RM = W x (1 + 0.025 x R)Wathan: 1RM = (100 x W) / (48.8 + (53.8 x e-0.075 x R))where1RM = One Repetition Maximum W = Weight Lifted R = Repetitions Completed e = Euler's Number = 2.71828 (approximately) Quote Link to comment Share on other sites More sharing options...
