It depends on the angle of the machine. Let’s guess that the bottom angle, closest to where your feet are placed, is 60 degrees. We can now find the mass of whatever object moves parallel to the surface upon which we are working. So if you have 100kgs on the machine (or you weigh 100kgs combined with the sled, you get the idea) at a 60o angle the equation would look like this: Mass being moved=100kgs*Sin(60). Which would give you 86.6kgs of mass to be repped! Luckily these machines glide very easily so we don’t really need to take into account friction, but if you’ve got a really sticky one we can talk about that, too.
You’ll be able to do a lot more weight on this than normal squats because of the added stability of the back pad and the consistent groove the machine makes you work.
I don’t think it needs to be this complicated.
TheTick, work up to whatever rep range you usually do. Then you’ll have an idea of the strength difference. If you’re getting stronger with an exercise, then you’re getting stronger period.
