Can't do push ups, Please help!

So i have pretty bad wrists (carpal on right, surgery on my left) and my trainer had me plank during the pushup portion of our session when i first couldnt do a pushup. I then bought some fantastic wrist gloves (Wrist Assured Gloves) and since I bought those i slowly have worked my way up from lower plank pushups (forearms -> down ---> back to plank on forearms) to modified push ups to bear crawl pushups to regular pushups. Since working out for a bit, i have found my carpal to flare up much less. Strength training + slow and steady work has changed everything.

Also, do a search for Yoga Wrist Pushups for Carpal video. Its definitely helpful.

Dumbbell chest press is a great way to go... That's because your wrists down have to flex like when you do push ups. I do suspension training with a lady who has Carpal tunnel in both wrists, but by getting a straight weighted bar... I like the 30 and 40 pound... Gives a nice clearance... She can do them without pain. The problem is putting your hands flat on the ground and bending them. That's why you see guys doing them on their knuckle. To use the bar, put it in front of you and put 4 small weights in front and behind... So it can't roll away and then grab the bar so you wrist is not bent... You can also use the bar on the smith machine... That's great as you can adjust how high the bar is to your level. I hope this helps and like the guy before said... Stop when it hurts... It's your bodies way of letting you know before an injury.
