Im sure most of you know that your leg press is alot higher than your squat.

Doing some physics work we can calculate it all out.

As we know at an angle weight is decreased.

So if that sled is at a 45deg angle and we know that the sin of things are vertical.

We can say the the x weight times the sin(45) is what you would have if it were at a 90 aka vertical. ..(sin(90)=1

So x * sin(45)= x*.707

so say you can leg press 500

500*.707=354lbs

.......................

But if you do the numbers im sure you can tell that this method is unreliable and you wold find yourself crushed on the squat machine if you tried to attempt it.

Another method i found on the net was to just divide x by 1.8..(pretty much someone avg out there squat to leg press ratio and came out with this number.

for me however it was still a bit high, but it is closer to where i probably should be at.

so say you can leg press 500lbsdivi

500/1.8= 278lbs

dividing by half is most peoples best bet IMO, but the first method is technically how much you are leg pressing.

What.... weights? Huh.....

Trying to figure how much you can do in one exercise based on how you can do another is about as useful as guessing a SPL score. We may know everything about your past performances, and how much you did with this, but until you do it there is no real 'good' guess.
