push ups are bad for your vertebrae and they are over rated..
of late light weights and do this regularly rather consequently a lot of cargo and your are grunting like an animal..walk for strenth training and do a lot of reps....of lighter mass because you won't give up as efficient when you get bored beside exercise.
join the military..they will thrash you in shape surrounded by a few weeks...and it won't be bad to drink a better too
yea like the other guy said.. lots of speed weights. do something you can do a right 25 reps with on anything and do them duly fast. this will oblige your speed, help you gain for a moment weight, etc. drop rope is really great too. it helps your speed, hand/eye coordination, verticle. work on your 40 time too.
americanrunning.org have a 12 wk. program to get you started if it's be a long time since you're worked-out. Try doing modified push-ups (off your knees) with a straight posterior and do them as fast as you can. Start at one set of 5 reps. Do them everyother sunshine. Add a couple each time until you hit 50. Don't exceed 50 or you'll achieve bored with them.
Try training beside free-weights or machines. Free-weights are better for overall strength because you have to use supporting muscles for symmetry.
