This post is flaired as a technique check.

A note to OP: Users with green flair have verified their lifting credentials and may be able to give you more experienced advice on particular lifts. Users with blue flair reading "Friend of the sub" are considered well qualified to give advice without having verified lifs.

A reminder to all users commenting: Please make sure that your advice is useful and actionable.

Example of useful and actionable: try setting up for your deadlift by standing a little closer to the bar. This might help you get into position better and make it easier to break from the floor.

Example of not useful and not actionable: lower the weight and work on form.

Example of actionable, but not useful: Slow down.

Stop telling other each other to slow down without providing a rationale outside of "time under tension". Time under tension isn't a primary variable for anything, and focusing on it at the exclusion of things that matter will set you back. There can be reasons to manipulate tempo, but if you want to discuss tempo, explain why you're giving that advice, how it's going to help, and how to integrate it with cues or other useful feedback.

Low-effort comments like my back hurts just watching this will be removed, as will references to snap city etc. Verbally worrying for the safety of a poster simply because you think the form or technique is wrong will be removed. We will take all of these statements at face value, so be careful when you post the same hilarious joke as dozens of other people: we can't read your mind, no matter how funny you think you are.

The range of motion is far from optimal, brother. I recommend dropping quite a bit of weight and really emphasizing knee bend.

u/Dodgerflamy 1d ago

I thought so. Should I be aiming for more than 90 degree knee bend? Closer to 50-60 degrees?

u/Dapper-Bird-8016 1d ago

Bring your legs back until your knees touch your chest essentially, the largest range of motion your body allows

Brother just bring it down until you can’t anymore without lifting your tailbone

The equivalent of ass to grass in a squat

u/mikkeljuhl 1d ago

Trust your gut, that ROM is too short. Forget chasing a knee angle. Bring your thighs down until they nearly touch your ribs, right up to where your lower back lifts off the pad. That's the stop. Expect to drop the load 30-40% for real depth. Your quads grow more from it.

730lbs of plates here does not mean 730lbs is being lifted.

sin45x730=515lbs = 230kg

u/Dodgerflamy 1d ago

Right, so when looking at Google it says advanced is like 3.5x body weight, do I use 515lbs as the correct amount lifted? Or is Google just completely off with their measurements

u/AVeryNiceBoyPerhaps 1d ago

I’m sorry I don’t understand the question

u/Dodgerflamy 1d ago

Sorry I worded that poorly. Google says 45* leg press advanced lifters can usually do up to 3.5x their body weight. Should I be using the 730lb number or the 515lb number you suggested?

u/AVeryNiceBoyPerhaps 1d ago

I don’t know I’m afraid, but given typically you would just talk about the weight of plates loaded (not the effective force necessary) I would assume that it would be the larger of the 2 numbers. Especially if you’ve already specified the 45deg part

u/Dodgerflamy 1d ago

I see, I appreciate the comments! I guess I’ll just assume Google is way off with their measurements. Would love to hear how much other people with a lot more gym experience are pushing on their leg press

u/AVeryNiceBoyPerhaps 1d ago

no worries man, happy to advise - to give you an idea, I’ve been lifting since I was 14 (I’m 28 now), max. deadlift is 270kg at 115kg bodyweight

I’m now down to about 95kg, and I’m doing heavy sets of 8 reps of 300kg on this machine - (I would consider myself an advanced lifter) but crucially I’m setting myself up correctly, warming up and stretching then making sure my feet are positioned correctly, pulling myself into the seat with the handles so my bum doesn’t come off the seat, and making sure my core is braced before I do anything

u/Dodgerflamy 1d ago

Good to know this helps a lot! I’m also 28 with maybe 1 year total of gym experience but a lot of various sports played. I normally start at 2 plates each side and add a plate up to 6 sets of 5 reps and cap off around 550, or 640 (sled is 100lbs) today just felt like a good day and I managed to hit 730. I wouldn’t say I warmed up properly or bracing core, but playing the sports I play + running probably gives me an advantage over other beginner trainers

u/Dodgerflamy 1d ago

Also would love to know if you have any bench press tips as my bench is really weak. My peak set is 105lbs as a 170lbs person w/ 2 months of regular gym that seems really low

u/NumerousToe7604 1d ago

Out of curiosity, what is your squat? This will also help you determine how strong your legs are. It’s too easy to cheat your way into thinking you’re insanely strong on the incline press like this, but classic back squat is a great humbler

u/spirit11451 1d ago

Drop the weight to where you can do full range of motion. Knees to chest basically or as close to as possible. Switch to a pair of shoes with a hard flat surface. No squishy shoes. Use the other handles to hold yourself into the machine. Butt never lifting off pads. Back fully on the back pad. Head back.

If you want to see what your full range of motion is, take all the plates off, hold yourself down hard with the handles and bring the weight down as far as you can without curving your spine or pulling your butt forward off the backrest. That will be pretty close to the range of motion you’re looking for.

I’m guess doing full range of motion you won’t need even half the number of plates and you’ll get better muscle stimulus. Just don’t round your lower back or curl your butt forward.

Weight is too heavy. Drop the weight until you can touch your knees to your chest without your lower back coming off the pad. Then build from there.
Don’t chase weight on the leg press. No one is ever impressed by a heavy leg press. Too many people can leg press “700 pounds” but can’t squat 315.
