    Squat vs. leg press ratio

    so anyways this has been bothering for a while and i know this is a stupid question and doing more on one exercise doesnt mean you'll do a certain amount on the other one.

    but anyways here it is, i max 275lb on squat, max 500lb on leg press. i always expected to do more on leg press and whatever but not by that much, is it normal? i go parallel on squat, ive tried going lower but i cant keep my balance, in leg press i go as far down as possible.

    so srry for the stupid question, do u guys think its normal and what are ur squat and leg press max

    Right now I squat 3 plates + bar (315) but my press is 630
    So your results don't seem that off to me.

    Squat to Leg Press Ratio = Squat amount times (*) the square root of the stupidity of such questions divided by (/) the weight of your brain in pounds = leg press

    i've heard from trainers at my gym that the leg press (on the machine) is a pretty useless workout. the reasoning being that its such an un-natural form. I'm not sure if this is true but i've since stopped doing it and focus primarily on squats.

    any truth to this??!

    I don't know, but it seems to work great for me. I like squats too, don't get me wrong, but I love the leg press

    First of all, there is no direct correlation, since squats use other muscles, which may or may not be the weak link in the lift. They are two very different exercises, though obviously they work some of the same muscles.

    Second, with squats you are also lifting your body weight. So, if you squat 275, and weigh 175 , then you are actually lifting 450 lbs. (no, you can't claim you squat 450, however). On a 45 degree seated leg press (if that's the machine you're referring to) you are not lifting the entire weight you have loaded, nor are you lifting your body weight.

    Looked at this way, it's your leg press weight, if anything, that may not be up to par.

    this makes alot more sense now, i wasnt think about my bodyweight with the squats either, and yea, i guess the 45 degree angle takes off some of the weight ur doing. thnks for the explanation, rep.

    oh lol and i wish i could say i squat that much :P

    in my experience, leg press is usually about triple squat weight.

    I don't think it's a stupid question. I kind of wondered about that ratio myself.

    I think maybe the squat just feels wrong for some people. I can leg press over 900lbs for reps but my max squat is only like 315. I feel a weird pain in my lower back like my spine is trying to pop thru my skin if I go heavy on squats.

    99% of the time you will legpress more than squat. but the ratio depends on the machine and angle. I can squat 365 and legpress 1080 (12 plates). But I use the same leg press machine everytime so i know how much weight to add. If i used a different one, I have no clue and would probably start light and increase slowly to see what i can do. waste of energy and time.

    http://www.scoobysworkshop.com/squat...ssnoteffective



    "People use the argument that since they can do way more weight on the leg press than they can on the squat that this makes the squat a better, "more efficient" exercise. This ridiculous claim shows the complete lack of understanding of basic physics by bodybuilders and the public at large. If you really want to succeed at bodybuilding, you need to know your science! In the case of the 45 degree leg press, its simple leverage that lets you lift more than you can squat. To get 495 pounds of resistance for your legs in the 45 degree leg press requires loading the machine with 700 pounds of weight (495/cosine(45)). In addition, the squatter is lifting their own bodyweight in addition to the 495 pound bar, this is not the case for the leg presser. If the bodybuilder pictured weighs 200 pounds, their legs are really lifting closer to 695 pounds when squatting so when doing the leg press they would need to do 980 pounds (695/cosine(45)) on the leg press to get the same leg workout. So for this 200 pound bodybuilder, 495 pounds on the squats is about the same as 980 pounds on the 45 degree leg press - not because squats are 'more effective' but because of physics."

    i'm in trouble then on leg press. often wondered why i suck so badly at them.

    squat 310 + bodyweight 165 = 475

    leg press 450 x cos 45degrees (.707)= 318

    My best squat is 455x6, and leg press is 540x6. I don't leg press often though and I could probably get up to more like 630x6 if I wanted to. That is knees to chest on leg press, basically bottoming out the machine I use.

    but anyways here it is, i max 275lb on squat, max 500lb on leg press. i always expected to do more on leg press and whatever but not by that much, is it normal? i go parallel on squat, ive tried going lower but i cant keep my balance, in leg press i go as far down as possible.

    so srry for the stupid question, do u guys think its normal and what are ur squat and leg press max
    NO Real Answer

    There no way to answer that question.

    There are too many variables with a Leg Press. The sled angle being one.

    So, the amount of weight you can push up on one Leg Press often is much different than what you can drive up on another.

    Mate, your squat is the only thing that matters. I honestly couldn't give a fk if you could leg press 1000lbs+ it honestly doesn't impress me. Just use the leg press to get some quality reps in after your squats. Don't worry about the weight on the leg press, just worry about the weight on your squat and keep at it op.

    Leg Press is A Good Tool.

    Leg Press-Useful Tool

    The Leg Press has its place in training.

    It definitely allows you to overload the legs.

    It does this by taking the stabilizer muscles out of the equation.

    Thus, the primary muscle are overloaded.

    The Squat

    The limiting factor in a squat is the core, specially the lower back.

    The lower back tires before the legs are completely overloaded.

    Thus, exercise that take the lower back out of the equation allow you to maximize you leg training.

    Leg Movement

    The movements below take that lower back out of the equation.

    In performing them, holding on to something like a Power Rack in performing them allows you to use a greater load. That because you are minimizing the stabilizer muscle.

    1) Step Ups

    2) Belt Squats

    Combining Prime and Stabilizer Work

    One method of maxing the legs out is to...

    1) Perform Squats then the Leg Press.

    2) With Step Ups and Belt Squats, the same applies.

    Preform them without holding on to a Power Rack. Then follow that exercise with them holding on to the Power Rack.

    Deadlift Training

    The Leg Press is more effective at increasing the Deadlift than the Squat.

    This was really helpful. I knew the angle threw off the comparison and it took out the back which is my weak point for sure. At 250 of chub I'm squating 405 ◊ 2 (haven't tried any more yet) but felt I could go harder. Today I leg pressed 800 ◊ 10 and felt I could have easily done more. This post gives me confidence to try for the 1000. Not without someone there just in case but I'm gonna try it!

    Physics

    There is some physics here that can answer.

    Basically the sin of the angle of the press gives you the equivalent, but then you have to factor in your weight. Seems to be about 20% more of your body weight needed to adjust for press not pushing the upper part of your body.

    This guy observes this: bodybuilding.com/fun/shannon1.htm

    I've experimented physics formula that gets it, but the answer is: Divide by 1.8: that is the observation made, and backed up to an adjusted incline calculation.

    The answer over many places "they are not comparable" seem to be given far too often... they can be compared quite accurately.

    So, if you are doing a 130kg squat, your 45 degree incline would be about 235; give it a try.

    Technically it is the sin of angle the way angles are usually measure, but the cos and sin of 45 are the same physicsclassroom.com/class/vectors/Lesson-3/Inclined-Planes (sin is the parallel force, cos is the perpendicular force) ... but you have to factor in the amount of body weight on a squat... best to just go with 1.8 and leave it at that.
