Since I have a physical disability cannot exercise outside what can I do inside?

You can read book, grow you mind, to be honest the greatest form of exercise is the one of the mind, have you ever heard that knowledge is power.
Funny right, if you can increase you IQ to a very high level of reasoning and acquire a lot of knowledge on different area of life, by understanding nature, humas animal and other you can become one of the most powerful being to ever exist, life is not about physical power, true power comes from the mind comes from intense knowledge strategy and tactics. Am not asking you to do am only giving you a suggestion it's left for you to decide what you want for yourself, have a nice day ahead dear.
