I want to get good abs and arm muscles. What exercises can i do at home for like 30mins a day that would build these up? My abs are already pretty good but ive never trained my arms...

if you dont want to spend any money:

arms: push ups. start on knees and as they get easier over time get on your toes. do some research and see the different types of push ups that are there. example you can do a triangle push up.

abs" look up on the computer how to work every muscle in your abs. obliques, lower abs, internal. etc

now if you want to spend money:

for arms buy the perfect push up. my bf got that and his arms are getting huge

and for abs use one of those big balls.

You really need weight to build up your arms. Invest in a cheap set of dumbells or a barbell and do standard curls. Make sure you get full range of motion and use proper technique. You can do push ups which will hit your triceps a bit but without heavy resistance, you wont build much mass so I recomend eventually getting a bench. Abs can be built simply by sit ups.
