Impossible, I agree; but absolutely worthwhile. I'll probably be on week 5 day 1 for the rest of my life but at least its good exercise.

I've had to give up the pushups for a while. I totaled my left hand and wrist two weeks ago. I can finally make a fist again...

On the other, uh, hand I've managed to run four miles both Wednesday night and again tonight thanks to a free treadmill. It took me months to get to this point working out every other night, but I'm thinking it's pretty good. My goal now is to run that far faster. Right now I'm doing 4.5mph. My next goal is to do it at 5mph.

It really does feel good, doesn't it. Like I'm taking charge of something in my life.

Hmm, I think this pushup program suffers from the same problem than some of the similar ones I've tried in the past. The progression is fine initially but then you hit a certain plateau past which it's really hard to get. Here's another pushup routine, which may be methodologically better:

Part of the problem may be related to one's physical build as well. I used to be very active in the past (boxing, martial arts) but as a tall, fairly lightly built guy I could never get past about 50 pushups. Some problem with the bench press though I've been much better on some other lifts. In my experience guys with shorter arms can peform such exercises more easily because the leverage is different.

But anyway, I also gave this program a shot. Since I don't work out as hard as I used to it seemed a good idea. But I can tell right now after just a week into the routine (I started with Week 3) that I won't be ready for 100 reps any time soon. Anyway, even just getting back to 50 would be plenty nice for starters...

Must say I'm kinda glad to hear I'm not the only one stuck. For me it's week 3.

Like Blast said, even if this 6-week program is impossible it still has value. It is simple enough that it has re-started my languishing fitness routine, which is now branching out into other activities and exercises (like tabata squats and running).

Glad to have found mention of it here as well as Tom_L's link to an alternative program and the pull-up programs/DIY bar.

I'm somewhere in the middle of "week" 4. I did a test to see how many I could do at once, and I got fifty without a great deal of exertion. I think it works: when I started, I could hardly do 10!

I had a major issue also with week 3. I switched to every day (5 days on, two days off) and finally got through. I've hit the same wall at week 5 day 1, and I've been here for a while. Still making slow progress though. My last max test was 43. I'm thinking of testing again today to see if my max has upped.

Just did a test and maxed at 51. This is about twice my initial test amount of 25. Hard to believe I've been at this loyally for so many weeks and I'm only 1/2 way to 100. I look and feel good though so I'm happy.

Week 5, day one is tough! I was just able to squeeze out 25, the second to last set. I'll try again in a few days.

Finally, in my 15th week I completed week 5 day 1 column 3! The quest continues.....

I still haven't been able to do a single pushup since I wrecked my hand/wrist over a six weeks ago. I'm starting to wonder if I'll ever be able to again.
