it will improve endurance and speed, if you throw fast strong consecutive punches for about 30 seconds, then quickly jump down do some explosive pushups and jump back up and do some more fast strong punches and combo's and take a small break and repeat(you should be well out of breath when you stop one rep)
doing things explosively is getting your body used to getting oxygen quickly to muscles and the stretching and hard contraction of muscles is what increases muscle size do this and you'll have size(with a limit depending on your body type)while having very strong and well defined muscles
