So, how does biking manage to burn so many calories? Well, it's all about resistance and effort. When you're pedaling, you're using your leg muscles to push against the resistance of the pedals, which makes your body work harder and burn more calories. It's like doing a never-ending set of squats, but way more fun!
And, if you're going uphill or riding on a tough terrain, you'll burn even more calories because your body has to work harder to overcome the challenge. It's like your body is saying, "Oh, you think you can handle this hill? Well, let's see how you do!" And then it proceeds to burn a ton of calories just to prove a point.
