How to improve IQ?

After an online debate in a videogame a guy said he has 140 IQ and that i am stupid i claimed i am smarter.. So later on i wanted to check my IQ. I tried a few online tests(visual iq tests) but my mind melted for a straight 40 min. It doesn't matter how hard i tried my IQ results were 89. Its devastating.. How can i improve my IQ?
