There is no one-size-fits-all method for getting someone to follow you on Instagram. Requesting followers by tagging them in posts or comments, leveraging popular hashtags relating to your hobbies, and following similar users are all examples of techniques. Include a link to your Instagram profile in your other social media biographies or on your website to ask people to follow you. If you're lucky, people will find your profile and follow you without you having to do anything.
