To measure the angle subtended by your sidesplit! (the angle between your legs):

EQUIPMENT
-a measuring tape of some description
-a calculator that can cope with sin, cos and tan (trigonometry)

(no maths skill required)

METHOD
a) Lower yourself into the splits, and measure (use centimetres)
i) - the distance between your heels (overestimate this a tiny amount) CALL THIS "D"
ii) - the height of the triangle between the floor and your legs (overestimate this a tiny amount too) CALL THIS "H"

The overestimation is to take into account that you wont be forming a perfect triangle.

b) Rise from the splits and measure the height from the floor to your groin (as in part ii), and overestimating by a couple of centimetres again) CALL THIS "L" (it is the length of your leg)

c) There are 4 ways to determine the angle. I will explain the two most reliable ones here:

ARCCOSINE METHOD (use calculator)
~Divide H by L
~find cos^-1 of that
~multiply by two

ARCTANGENT METHOD (use calculator)
~Divide D by H
~Divide that by two
~find tan^-1 of that
~multiply by two


You will get a slightly different answer each time, because of your measuring accuracy, but they will probably be within a few degrees, eg 123 and 126 degrees.

Hope this helps some people

I remember geometry. Should have passed it.

you know, you could have spent your time much better actually stretching rather than thinking all that fairly useless stuff up :good:

Why would one want to know his sidesplit angle?

Curiosity?

It's just harmless fun. As long as it doesn't stop you stretching well, I don't see the problem.

TKD Andy... i wasnt warmed up at the time so stretching wouldnt have benefitted me much lol. (and it wasnt any trouble to think up... i do far more advanced stuff in class on a daily basis)

I think it can be useful... it can give you mezzanaine goals, ie 150 degrees, if 180 is too hard for a short-term target. Admittedly you could just as well go by the height off the floor.

(im at 140 degrees, incidentally)

I say just use a protractor.

why bother working it out?

Its pretty pointless, i mean when are you ever going to need to know it?

Unless its over 180 i dont think anyone will really be interested.

Well yea, but I think the ultimate goal for everyone is 180, in the short term or the long term. Reaching a certain number goal before then isn't going to help, you just need to keep on trying to progress down to the final goal. Reaching the smaller goals before the full sidesplit is sorta obvious and redundant, since even if you don't set those goals, you're going to be progressively reaching them, whether you're thinking about it or not.

lol this isnt so that people can go around wearing T-shirts showing off their angles:

"LOOK AT ME!!!! 152 DEGREES!!!"
"167 DEGREES!!! THATS HOT!!!"

Its for personal interest and an alternative form of self-monitoring

And Skilkat98X, do you really own such a large protrator?!

How about, when my balls touch the ground, I'm in the sidesplit.

Man there are more than 5 months sinse i didnt smoked anything and is better even with stretching. I hate smoking and all other drugs. I will never smoke again.

You don't really know your sidesplit angle to progress with it. Measuring one of those things used to calculate it (distance between feet, height from ground) is easier and can gauge progress. Knowing the angle is only useful for comparing with other people, which isn't the point.

And Skilkat98X,
Ahaahha!
There's another one to add to my list of funny name misspellings...
