realistically how much of your body weight are you actually pressing doing pushups?
40%?

60-65. Check on a weight scale
oh that's actually a good idea
Doubt this. I'm sure I can't benchpress 22kg dumbbells for one rep but can do 12 pushup reps.
Dumbells need more stabilization.
You're cheating on pushups.
Interesting. Does that hold true for barbell vs dumbbell? I have no idea how much I can do with a barbell. Not him and I only have dumbbells.
On the contrary, I do full ROM pushups with less than 45° arm angle
You probably could tbh, i max out around 45-50 pushups and can do 15-16 reps with 50lb dumbells inclined press
your probably cheating on pushups, and also dumbells require different skills and stability to lift.
u don't doubt u're just moronic
it depends on where you put your palms in relation to body and how much ur shoulders get protracted and when - it's around 10 kilos for me on legs, 13% or so
just use chat gpt, huwhy bother with hs maff nobody uses irl?
>can not press 22kg dumbbells
No one is going to call this dyel out?
65kg out of 94kg for me
It’s about 2/3rds.
Think this is a statics math problem. Your body is basically a triangle frame with two fixed points of contact at the hands and feet that resist all forces in the x and y axis. You need to calculate the reactive force at all points. There's no forces in the x axis so it'd probably be pretty easy if you cared enough to solve it. Probably need your mass, acceleration of gravity at 9.81m/s^2, and either the angles inside your triangle or the distances of the sides of your triangle.
Wouldn't you need dynamics because you are moving?
I think all you need is to find the reactive force at the hands in terms of force (Newtons) for the before and after states. Delta y is what you're looking for I think, so whatever y is at the 2nd state - the y at the 1st state should be how much force you're using to lift yourself. This is just me armchair engineering though.
>just me armchair engineering
Yeah I can tell.
>hasn't even mentioned the center of gravity yet.
Should probably be around the belt buckle so you could estimate about 2/3rds across the triangle from the left side for simplicity. I dont really care so Im not going to go through the trouble of solving it
The newtons for both will be basically the same, giving you a delta of 0. You need to find the force you are exerting moving between the positions. Measuring the force in those states tells you nothing
Why solve difficult math problems when you can let nature "calculate" it for you.
1. Place a scale under your hands.
2. Measure the weight over the course of a few slow pushups. The time interval for the measurements doesn't really matter, but leaving it too wide causes problems. 2 measurements per second sounds about right to my ears. You can film the scale to do this, and afterwards review it to create the data
3. Using this data one can create a graph showing the force required for whatever part of the exercise
No need for fancy mathematics, and the results will be quarantined to be close to the truth. Bless you
Black folk use measurements. Whites do math. homosexual.
Gravity is Black person shit, noted. All physics is ultimately based on measurements. Someone at some point in history had to measure and then find a mathematical representation for the observed data. You are depending a mountain of "Black folk" as you call them, to allow you to just calculate these things.
To depend on someone, means to be lower than them; you are lower than Black folk.
there's uncertainty in all of this, but here's a shot.
> google tells me center of mass (com) is ≈10cm below the navel. this is different for everyone and mass distributions, so this is first point of uncertainty.
> measure the distance from floor (feet) to 10cm below navel, do the same for distance from floor to shoulders. better yet, get this measurement when you're in a pushup pose. hard to measure, this is the second point of uncertainty. this will vary for everyone
> use pic rel. the force at your hands (F_R,hands) is related to your body mass times a ratio of feet-to-com distance (d_f) divided over total height, feet-to-shoulders (d_f + d_s)
example:
i'm about 6'3", distance from floor to com, d_f ≈ 105cm, distance from floor to shoulders, d_f + d_s ≈ 140cm. that term yields 0.75, or 75%. So ≈75% of my total body weight is exerted at my hands.
that estimate sounds high to me, but it may be reasonable.
yep, proof of whiteness also attached
Where you store mass matters too. Of you're leg heavy it's more difficult
Exactly
You don't have to actually do a pushup to measure the weight. Just put your hands on a scale and see what it reads
Oh great, it's literally rocket science
its not about the weight you are pressing, its about the torque you are overcoming.
Get into pseudo planche stuff.
70% i think decline/full range of motion pushups can get up to 90%. It wont translate directly into benchpress though, as the leverage is all different. pushups are great, and nothing feels more badass than doing like 5-600 in a day. Nonetheless,a fter more than 30 pushups, its great to do harder variations like weighted or decline or even like planche type work.
Depends on how you press. If you press with correct form its close to 80% according to my scale.
Hard push ups are almost as hard as dips.
85% at the bottom of the rep with perfect form and correct bracing.
why do my shoulder blades protrude to an extreme on the bottom of my pushups? is this rolled shoulders? like they look like fricking wings
what kind of wide ass scales do you guys have, you'd have to do a diamond pushup to have your hands on it
65% in a normal push up.
So basically 1/sqrt(2). Trigonometry chads... we cant stop winning
Yeah but some calculus or diff eq helps if you really want to determine the weight since the load changes throughout the exercise.
I do inclined pushups and the scale said 80%. I do weighted tho so I push slightly over 100% bw.
You're actually pressing more than your bodyweight. Your body doesn't change weight just because its laying down. But when you lay down ur increasing air pressure.
Dips are the superior exercise in every single way.
por que no los dos?
