Oh, fun WOD :-)

Squat, split or power snatches?

Cain said...

I'm still wondering about last night's WOD. We did our 75RM, but that does not mean we can snatch a Buick. How does that work?

I like how this WOD is titled "CF will wreck you" b/c yes it did. The word "sore" does not do justice to how I felt getting up this morning. Strangely enough, though, I love it!

Dan Hook said...

Ya, I love those mornings where I'm reminded just how essential the abs are to getting out of bed.

Evan said...

I see a question, but am not sure what is being asked. Cain, could you clarify a little, then I can have a stab at it?

Cain said...

Evan, I was just wondering why when 3RM is 92% 1RM that 75 reps conveys no information of 1RM.

Evan said...

Simple:

1. 92% is nothing but an estimate. Search around any you will find a range of percentages, and even online calculates, to give you approximate 1rm data. None of them are accurate, just formulaic guesses.

2. Since it is an estimate, the larger the numbers are, the greater the variance. So, you'll be hard pressed to find any chart that goes above 20rm (but usually, you only find 15 or 10 rm charts). Again, I would like to point out that they are estimates. Don't get caught up in the percentages.

Additionally:

Unless someone does 75 reps consecutively (i.e. "non-stop") they haven't done a 75 rep max. No one did a 75rm on Randy this week (nor has any CrossFitter anywhere, to my knowledge).

I hope that helps :-)

Evan said...

And just to further illustrate the absurdity:

http://www.criticalbench.com/cgi-bin/calcs/1repmax.cgi

Now, there are plenty of good articles on Critical Bench. I have nothing against the site. But to prove you can not invest allot into these calculators - enter anybody's 20 and 30 rep sets from the Deadlift and the Squat WODs from the other day.

Dan Hook and Matt's deadlifts break RAW records. Particularly Dan, I think we have a shot at Worlds, in your body weight category, with your deadlift estimate based on your set of 30!

Cain said...

Wow that is absurd! My 1RM for deadlift is 697 pounds! If I did that last set non stop of course. Everyone should plug in numbers to that site just to see the silliness.

Dan Hook said...

I'm guessing that someone found a function that matched 2,3,4 and 5 rep fairly well, and didn't bother to check it for other numbers.

For example, if you do 45 # for 100 reps, your 1RM is -26 #. Even worse, if you bump it up to 65 # for 100 reps, your 1RM goes to -37 lbs. I don't think I'd hire the programmer who came up with this.

Evan said...

I love that it gives negative loads.

Cain said...

it's weird, once you hit 36 reps the 1RM becomes negative...
