Yes I do. Right now I do them from my knees and can barely do any. So do I need to do them daily to get to the point of doing full ones? Whats exercises do you recommend to help me along? The push ups we do are the ones where your arms are against your ribs and hands flat and pointed away from the body. Any suggestions are appreciated!

doesn't that kiill your wrists. I can do fingers pointing forward[10+?], or palm facing each other [like your fingers pointing out] on my knuckles[3 -.-]. Im like 220 pounds. lol. keep doing

Anything you can do to build your chest, tricepts, and core (abdominals, obliques, and lower back).  My suggestion is to start doing a regular pushup.  If you can not do one regular pushup, have someone assist you buy putting a towel under your hips and holding the ends above your butt(kinda like a rope) and helping reduce your bodyweight.  If you don't have anyone around that can help you like that, start doing the pushups on the stairs.  Start at the first stair where you have difficulty getting 10 repititions in.  Do 3 sets of 10 or failure.  Make sure you can at least do 1 set of 10.  As you get stronger, move down a step and start over 3x10 or failure.  Keep repeating the process until you can do them flat on the floor.

For tricepts, do chair dips (3 sets to failure).

Crunches, leg lifts, reverse crunches for core workout.

Hope this helps!

Pushups

The only way to do them is really just to do them.  There is nothing wrong with doing pushups on your knees if that is the only way you can do them.  If I was your personal trainer at a local health club I would tell you that I would rather see you do 25 pushups on your knees then not being able to do any at all.  Just set a goal to do 5 regular pushups every day 3 times per day.  Fight your way through it and as time progresses just add one a week until you reach where you want to be.

like sarge said, anything that can build muscles in those areas will help with pushup. 

if you are having hard time doing it on your knees, then try doing it standing up against the wall to build up some strength first (your hands will be about your chest/shoulder high, and your feet will be further away from the wall than your shoulders to create some resistance against your arms). 

if you find that too easy, then you can do it against a kitchen counter or a dining room table (hands on the edge of the table, again feet are further away from the table then your shoulders). 

the lower your hands and the further your feet are away from the wall/table, the harder it will be.  find a comfortable height and distance for your hands and feet placement - areas where you can do a certain number of reps (e.g., 10).  once you set your baseline repeptition, then start increasing the rep by 1 every 2-3 days till you can do a certain number of reps (e.g., 20).  then find a place where you can put your hands a bit lower and start all over again until you can do it on your knees, and eventually on your hands and feet on the floor. 

i recomend bench press because its basically the same motion as a push up except upside down.

I do lift a few days a week. I am looking to put together a program but need some ideas. The place I go to work out is my local park and rec. It has a few treadmills,ellipticals,a sitting type elliptical, airdyne bike,a vectra machine that you can do bench press,shoulder press,lat pull down,rows,tricep extension,leg extension,weighted sit ups ,  and a few others. There are also dumbells from 3lb to I think 40 or 50 lbs. For instance yesterday I had very little time so I did 30min of elliptical and today I did bench press 40lbs 3 sets of 10, shoulder press started with 40 and had to drop to 30 and had a heck of a time getting 3x10, 40lb deadlifts 3x10 ( a 20lb dumb bell in each hand) I think I might be doing them wrong because it seemed to easy,lat pull down 40lb 3x10, and 45 min of elliptical. I will make a point to do sit ups everyday.

I've always tended towards full pushups but found it hard to get back to them after a break. I just practiced at home, shallow then full depth and I've got my strength back now.

The wall/counter/stairs thing really works too.

Slightly off topic but forgive me - I'm a girl. I've heard that doing full pushups can damage the womb becuase of stress put on internal organs. Anyone know if there's any truth to this?

I'm pretty sure it doesn't hurt the womb.

Remember to keep your stomach tight whether you're doing knee push-ups or toe push-ups.  Not like holding your breath, more like bracing yourself for a punch to the stomach.

Also, try doing toe push-ups on the stairs.  Start with a higher incline, and gradually work your way down to flat on the floor.  (Note to macho men: this technique works well for one-armed push-ups, too.)

The most important thing is to be patient.  You don't get your next belt overnight (I hope), and it will take time and consistency to develop push-ups.  Good luck.
