Fingertip pushups generally aren't damaging, just difficult. Chickenwrists can be incredibly damaging, I've seen two students in other schools sprain their wrists while doing them.

Not especially helpful for the dojo but one can get little stand-things to do press-ups on which give you the grip of a knuckle press-up but without the actual pressure on the knuckles. If I knew how to put pictures onto this message I'd find a picture of them but I don't!
Okay if you go to the following site http://www.argos.co.uk and put in product code 300/3327 you will see what I mean! I am sure any exercise shop will have similar but I know there is a picture on this site!
Personally I wouldn't do knuckle press-ups even if I could! It is FAR too much pressure on too small an area of the body - like an elephant wearing stiletto shoes! Remember pressure = force/area so the whole weight of your body is split between the two soles of your feet and the few cm^2 contact area between your knuckles and the hard floor. When you were performing these on carpet there was more area in contact as well as the cushioning, which spread the load a bit. As you do a job where manual dexterity is crucial you would be mad to continue knuckle press-ups on hard surfaces. If you want to toughen up the knuckles a bit, try punching into sand or something or at least use a padded, well-sprung makiwara!

In our dojo we do some knuckle pushups, but it's usually only adult blackbelts. It's not a good idea for kids to do them because their wrists aren't strong enough.
I would suggest doing maybe half of your pushups on your knuckles as a nice compromise to save your typing, if you want to do both.
Anyway, I don't see where they do anything other than hurt your thumbs.
What does anyone think of doing pushups on two fingers? If any of us can

Yeah, I bought a pair of those from argos, they're great! They also allow a greater range of motion than pushups on the floor, which is great.

True! But without over stretching the shoulder joints. Handy wee things! Not at all dear either.

I've seen those at sporting goods stores and almost picked them up several times, but I figured I might as well wait to see if I ever evolve into the type of karateka who would actually do pushups at home on purpose. Right now, that's just not going to happen.
I've been limiting it to 10 or so knuckle pushups per practice, and do the rest on palms or sometimes fingertips. My sensei says it's not just for knucle conditioning, but that it also trains the correct position for punching.
Monkeygirl, correct me if I'm wrong, but if you're doing knuckle pushups properly you should not be hurting your thumbs?? All the weight should be on the front 2 knuckles, the thumbs shouldn't even be touching the ground. |

What ? That doesn't make sense.. The reason you do knuckle push ups is to make your wrists stronger, therefore a harder punch, etc.
That's like saying you shouldn't spar because you can't fight well enough yet.

Yes, it does give the correct posture for some punches but to be honest its better to train that simply by practicing the punch over and over, works faster than the pushups too.
