Playing with the % of BW in a pushup and electric scale

So I was bored and went to do a weigh in. 168 today. So I get the idea let's really calculate instead of guesstimate bodyweight in a pushup position.

Standard pushup position where the bottom is elbows to side shows 130 pounds.

Decline pushup at 30 shows 140 pounds. I put my feet on a newspaper on top of the dining table which is lower than the kitchen countertop.

I'll do Kitchen countertop and top of the shelf to hopefully try 45 and 60 degree angles later. Roomie wanted to weigh himself after his bike ride. Might as well do incline pushup at those angles as well.

So far that means elbows in pushup pushes 78% of BW.

30 degree decline pushup pushes 83%

I will guess 45 degree hits 85-87 and 60 degrees hits 90.

I tried to test wall pushups but couldn't come up with any data. I'm thinking the sensor needs to be horizontal for it to test.

I will also guess that a pushup with elbows flared out does 70-75%. However, I cannot test this as there is only so much space for my hand placement.

If anything that irks me about this all is when I see beginning to intermediate coaches demand to the deck pushups from 4 and 5 yo. That is preposterous to imagine a 50 pound kid bench pressing 35 pounds. Sounds like I should test knee pushup later as well. Many team coach ask this of their gymnasts and get bent of shape when they as well have poor ROM besides position shape. That means with a 70 pound girl we're asking them to push nearly 50 pounds! Imagine a pre-teen girl at 90 or teenager at 110 and asking them do this. How about a teenage boy at 150.

Since I did my fair share of bench pressing this really hits it home for me. I prefer heavy DB bench nowadays as it doesn't seem to irritate my mussed up shoulders. A BW+ bench at a globogym last fall when on a day pass to show my friend the basic lifts, really showed irritated it more than the weight being heavy. 185 BP wasn't very impressive for myself, when I used to do sets of 250 when I was peaking.

I'll update this after he get's done for ****s and giggles.

Re: Playing with the % of BW in a pushup and electric scale

Very interesting numbers. Would 60% against a wall be about handstand PU angle against a wall? I am wondering so I can estimate what wait I will be needing to shoulder press to be able to do handstand pushup.

Re: Playing with the % of BW in a pushup and electric scale

Incline pushup at 60 degrees had 55 pounds of pressure. I put the scale on the dining table. That is 33%. Had a difficult time finding something for 45 degrees.

Incline pushup at 30 degrees had 105 pounds of pressure. That is 63%. Not too shabby.

Decline pushup at 45 degrees was 138 pounds. 83% Correctamundo.

Decline pushup at 60 degrees was 93%. I did both of these on the wall. Probably a little bit funky on angles. Tried wall HSPU position but it kept on teetering from side to side when I placed my hands on it. Probably could get the roomate to slide it under but there is only so much time to record the weight and it could mess with the measurement.

Enjoy. No more debating on the percentages now. No, I didn't measure each 3x nor would my roomate at 6 high 200's try it. It would be interesting to have other body shapes beside mine try this like Stephens slender and taller vs Big and Tall and short and skinny.

Re: Playing with the % of BW in a pushup and electric scale

Some new data is that I would be labeled as a Dolichomorph. Short torso and long limbs. This may affect the loads more so than mesomorph or brachiomorph.

Further testing requires a mesomorph for a general % and probably a brachiomorph just to check.

I may be writing an article about this professionally in the near future. Nothing that will probably mean $$$ in my pocket but more of an emphasis on proper pushup progression.

Dammit, I knew I forgot something. Forgot knee pushup raised and flat. I could all calculate this out via a formula but frankly, I'd rather take the measurements instead. Stuff for tomorrow.

I think I need to pseudo planche this somehow or have someone do that. Best I can do is lean way far over but I'm nowhere near a planche.

Pretty sure this doesn't equal a bench press since I don't think I can do 190 while benching elbows in. Maybe, dunno. Haven't tried in a long time with no real way to do it. Or care. Perhaps someone else does.

Re: Playing with the % of BW in a pushup and electric scale

Knee pushup on floor = 63% sounds high doesn't it?

elevated knee pushup on floor equivalent to 1.5 gymnastics panel mats or so = 50 %

30 degree decline pushup = 80%

45 degree incline = 47%

Could not get electronic scale to read at pseudo planche. Perhaps with a spot, but it would easier on a real scale.

Re: Playing with the % of BW in a pushup and electric scale

Nicolas, I didn't see your comment till now after I opened this thread. I'm thinking 60 degree isn't the right angle. 75 degree perhaps but just short of 90 is what I'm thinking really. 75 would be like a headstand where your forehead is placed in front of your hands in tripod position ( which is called a tripod headstand when the knees are placed on top of the elbows ). 75 degrees could also be if your body is arched.

If I use parallettes for the full ROM, it is 23". If I go to forehead it is a ROM of 13 inches. Now, I have long arms bare in mind, but that would be slightly more than half the distance traveled so half the work?

That really emasculates the handstand to headstand pushup doesn't it? Going Wide armed increases the ROM by about 2 inches.

So if that's half BW that would equal an elevated knee pushup. That doesn't sound right at all.

Re: Playing with the % of BW in a pushup and electric scale

Blair,

Are you testing the top and bottom positions? There should be some change, though not much. Also, to test a wider grip, place a bar or something an the scale, tare, and then choose the grip you want.

These percentages should be lower for a girl due to the different proportions of the body and lower center of gravity. For prepubscent gymnasts, it would be much closer.
