Oops , maybe i use wrong term....

What i mean by one set is do 3 times , each time is 8 repetition . Sorry , i still not yet fully inside this body building world , might make mistake.. @@ If according to your guys understanding , you all might think i do one one time of 8 repetition , LoL . Anyway thanks for your guys advice

. Body building indeed can consider another type of knowledge ,might needed trial and error.
3 sets X 8 reps
Which is 24 reps of DB presses/push ups (and pull ups and lunges) in a week?
That's seriously way too little to promote any significant growth. Look at hundredpushups.com. By week 3, it is 100++ push ups per session. What can that measly 24 reps do for you?
Seriously, if you can get to a gym, do Rippetoe or Stronglift 5x5.
If you're stuck at home the just do the simplefit.org thing... like right now! (you can do lunges instead of squats; DB press instead of push ups.) Then read up and ask around to gain more knowledge.
First, just freaking do something that works instead of wasting brain juice to come up with a routine-which-is-not-a-routine, can ah?
