There are many, many different forms of exercise, not just going to a gym. To make exercise fun, you have to find a type of exercise that you enjoy. If you hate lifting weights, then you will never enjoy your workouts and look forward to working out if you are going to lift weights. However, if you enjoy riding a bike, then going to a spin class or cross country bike riding, you will enjoy yourself.
Nobody likes doing something that they don't enjoy. When I was at school, I hated French lessons, so when I could, I dropped French. It's the same with exercise. If you don't enjoy what you do, at some point you will get fed up and quit, so you may as well start by choosing something that you enjoy. A lot of people won't know what they enjoy doing, exercise wise, until they try, so to start with it will be trial and error. If you are really keen on getting results, then you will most likely have to mix things up a little bit. So, for example, if you love doing boxing training, you can do most of your sessions as boxing. But it will be beneficial to throw in a few different types of workouts - for example, weight training, body weight circuits, sprints and so on. You may not enjoy them as much as the boxing, but they are effective and you will know that most of your workouts will be the thing that you love doing. It's similar to 'leg days' with weight lifters. I see so many people moaning about leg day in the gym, but they do it because it's beneficial, and they don't do it all the time.
To those people who say working out is boring, a waste of time etc, I would say they think that because they haven't found something that they enjoy. No real workout is easy, it will take hard work and dedication, but you can enjoy things that are difficult. People who know me know that I love formula 1, and those cars are extremely difficult to drive. You couldn't take someone off the street, put them in an f1 car, and ask them to drive it around a race track (even though I'm sure most young guys would say 'easy mate!'). But the guys who race those incredible machines, love what they do, love driving those cars, but it is not easy at all. It's the same with working out, you can enjoy something that is tough.
