Right now I work-out 6 days a week, mon-sat, and run every morning monday, wednesday, friday and saturday. I think it is unwise to do push-ups 6-days a week straight. so what do you suggest? should i do it 3 or 4, or 5 days out of the week? Should i do it on the days i run, or don't run, or should i do it all days i am not doing my arms or chest?

the reason i am asking this is because when i do push-ups, i want to be able to do more and more every time, and not be tired out easily.

thanks in advance, and sorry if this sounds a bit confusing.

I you're doing chest workouts with weights, why bother with pushups? Their rep range will be too high to encourage as much strength/size as progressively heavier weights.

If you're not doing weights at all, I would suppose that a good pushup routine would be to do multiple sets every two days as opposed to half as many sets every day.
