If you do 30 push-ups three times a week how long will it be to see results?

Answer 1

instead of doing 30 push-ups try to do 4 sets till failure. and switch different push-ups exercises every week, so lets say the first week you do Diamond push-ups, next week wide grip push-ups, the week after normal push-ups and after that Knuckle push-ups. after a few weeks try to do 2 or 3 push-ups exercises till failure and so on, try to keep changing your routine. Make sure to rest enough, so 3 times a week is good if you have 1 day of rest in between, don't forget to eat good too! you should be seeing results in no time :)

Answer 2

yes, but soon you start to see different type of gains. initially you will build muscle and look better for the first several months or year. afterwards, since your muscles are used to the movement and stress of a pushup you experience marginal gains.
