Estimating a 1RM from submaximal resistance - Personal Trainer Community - Forum

[DarkCreator]

As the title says I'd like to know what you have to do in order to estimate the 1RM via submaximal reisistance. In the book the citation is to the Essentials of Strength Training and Conditioning, pages 395-425. Since I only have the personal trainer book I was wondering if anyone was privy to this information. If there a simple style of equation or is there a different equation for each and every exercise?

Thanks Again!

Hey DC,

If you google "Estimated 1 Rep Max" this strength training page comes up:

http://www.strengthcats.com/strengthtesting.htm

I've used this page before. There is a table that estimates 1 RM but they also give a formula and factors for you to use in your own estimation.

I would think that the formula would be different for each exercise, but for bench press it should be spot on.

Ultimately though, it's just a trial and error and truthfully not many of your clients will be striving for one rep max or maximal weights.

Typically you don't want a client to only get one rep, but aim for 3 to 5 rep and estimate from there.

Hope that helps,

Dave

Yeah, that chart will be useful. I just found it weird how in the CPT text it was just, "there is a way to do it but we're not going to tell you." Right now, I'm going through a power lifting routine myself (5 sets of 3 reps) for bench (when my shoulder allows it), deadlifts, squats, rows and push presses. Since I don't always have someone at the gym to help me I've never tried to max out, so this info will be useful to me personally as well.
