Formular for calculating front lever difficulty

[ashley03]

I think I have created a pretty accurate formula for calculating how many times your body weight you are pulling down during front lever.

1 / sin(θ)

θ = angle between arm and body during front lever

Alternatively if you can't find θ:

1 / (√(a[sup]2[/sup] - b[sup]2[/sup]) / a)

a = armlength in meters.

b = distance from shoulder (when depressed) to center of mass in meters.

(This)

Example:

my arms are 0,6 m long and
there are 0,4 m from my depressed shoulders to my center of mass

1 / (√(0,6[sup]2[/sup] - 0,4[sup]2[/sup]) / 0,6) = 1,3416407865

When if I could do the front lever I would be pulling down about 1,3 times body weight.

I'm 99% sure that this formular is aplicable to both back lever and planche.

I'm currently in ninth grade, which means I have no formal education in physics (or anything else). So if someone smart could point out potential mistakes, it would be appreciated.

@ashley03 Math's not my strongest point, haha.

However this video might interest you:

This athlete, geekclimber has really gone indepth about the math and done the math stuff so you might really like this stuff. He's also done other videos about the front lever and the math is a big part of them all so do give them a spin!

@john0733 I love Geekclimber. “Since you asked for it, don’t fall asleep or walk away”

@john0733 I like geek climber but his point about a front lever being impossible for him is simply wrong. Also his math has very little carry over to real world. Long arms don’t make a front lever easier, a shorter moment arm does.

@ashley03 It’s a formula not a formular lmao

@usernamewastaken2023 Oops. It's formular in Danish. I'll fix it.

 

[ashley03]

Ah crap. I can't change the title.

@ashley03 Lol sorry I thought it was a typo, no need to stress if that’s your native language
