Calculate 1RM One Rep. Max.

Many athletes take a lot of time working out their 1RM manually by gradually increasing the weight they can move.

Other athletes, the ones with money, use isokinetic machinery that can actually calculate how much weight you're pushing and then give you an approximate figure (mass) that you're able to push.

With the former, by the time you figure out your supposed 1RM , you're probably tired from doing so many reps that it's a poor estimate of your 1RM.

This method uses mathematics so you don't get tired and you can even work off your memory of your last workout -- also , it's very difficult to calculate your 1RM on exercises such as the Barbell Squat , since eventually you can't lift the barbell onto your shoulders in order for you to squat with it.

Thanks for this.

I've been looking everywhere.Someone should make an app!!

It still doesn't explain why the 0.33 is the magic number.

@express375 Hi thanks for watching :) I agree, someone should make an app for gym particularities lol. Well yeah 0.0333 is just magic to me I'm not as good at magic-math as the video might suggest. It's like that old trick (Any number between 1-10 , x2 , +4 , divided by 2 , + the initial number) = 2 ... I just don't get how it works but it seems to work lol. To be critical of this video I would say that if you choose a light weight that you can move MANY times - it might give a very light

@TheJokerMarle weight for your 1RM that you may be able to EASILY move ... so in that sense I frown ... but so far it seems to be not too bad of a reflection of 1RM :) I've been using it ; sometimes I work my way up to my 1RM and it gets to be pretty close :)

Thanks again for watching !

Brains over braun, nice! One question though: Why specifically do we divide by 30 to get the supplimentary weight?

[TheJokerMarle]

@bongobuzza This is a good question. By doing this we just get a very rough estimate of the parameter we want. I'm glad someone's asked a question because the calculation should definately be up to scrutiny. I got this method of application by slowly working it out myself through guesses and then found out that Strength Coach Jim Wendler uses the same method LOL. There's another method called Brzycki Formula but it's more complex , I wanted this video to be very basic -- just to prevent injuries

Please read the video description to get a better understanding of why it is convenient to use the mathematical method of calculating 1RM.

@TheJokerMarle There are a few apps I've found and some online calculators. But some of them use a different number.

Basically,it's to find out when you are using your fast twitch fibers,which are the one's that get bigger/stronger.They seem to be in the 10 to 1 rep(failing on the last rep).
