Default Big boy push ups!!!!!!!

I am so excited! Last year I could do 20 push ups (but my head was up, didn't know that made it easier). So after I had baby I assumed I could at least get 4-5. NOPE, not even one. I was reduced to 7 girlie push ups. I kept at it but didn't try a military push up in a while. Playing around tonight I did 3 in perfect form a few hours after my chest/tri workout!! Not my old 20 but I am still thrilled!!!

Congrats Amy! I remember very clearly what it was like to finally be able to do a military (or big boy [img]/forum/images/graemlins/smile.gif[/img] ) pushup. Its a thrill! Before you know it you'll be back to doing 20, and more!

I was wondering just this morning as I was doing my measly, pathetic chest workout:
Do you lift your entire body weight when you do pushups (the big boy kind)? So if I weigh 150 lbs would I have to be able to lift 150 lbs to do a pushup??

When you do a pushup, you are exerting a moment about your point of rotation (where your toes touch the ground) that's equal to the moment (torque) gravity exerts using your bodyweight. If you looked at your body as rotating about where your toes touch the ground (what happens when you do a pushup), then you could analyze the forces pretty easily. If you weight 150 lbs, assume your center of gravity is about in the middle of your stomach. Say that location is 4'from your toes when you do pushups. As gravity acts downward through your CG (you can get the same moment by using a point load at the CG as the integrated moment over whole body), it exerts a moment of about 150 lbs*4 ft or 600 ft-lbs. about the pivot point. So when you do pushups, if the line of action of your pushing force is 5' from your toes, you have to exert the same torque in the opposite direction to raise your body (rotate about where your toes touch the floor) against gravity. So you have to exert 600 ft-lbs. You have a 5' moment arm, so you have to exert 120 lbs. of force.

This is obviously a crude analysis, but you get the idea. Bench probably requires more stabilizers, so the actual weight you could bench might drop a little more, but you can get ballpark figures this way. You can probably bench over half your bodyweight if you can do a guy-style pushup.

hold on, let me get my calculator....DORK! lol Yes, I'm a loser.

JP -
WHAT? Not being a dork but again I shall say WHAT??? Can you explain that in more simple terms? Like I did 3 military push ups and I weigh 142 - so what would you guess I could bench?

I can't bench my weight and I can now do them so I say no, you don't have to be able to bench that to do a push up.

A standard pushup is probably comparable to benching 75% of your body weight. Not science, just my personal observation.

I can do 6 pushups but I couldn't bench my weight for 6 reps... heck, not even for 1 rep, so it is not equivalent.
