Disagree. There are plenty of ways to burn calories... It's not so much "easy" as just not enduring it. Kinda like hockey, burn a chitton of calories and it's fun, doesn't mean it's easy, just something that you're not focusing on the fact that you're exercising. Need to find things like that. Some people love to run, it's not my bag. I run to train, but it's work. When I get on the bike, it's fun, like hockey.... I can do a monster climb, roadie or MTB & it's challenge, not means to an end.
