The title of this post asks a question: Which exercise burns the most calories?
The answer is simple. And it's the same no matter what new fangled gadgets come out or what experts say.
The exercise that burns the most calories is the one you actually do.
If you feel cheated, I apologize, but its true. Running burns more calories than riding the cycle. But if you hate to run, then what are the odds you'll keep doing it?
The only way to lead an active life is to enjoy it. Back in the old days, I would go the gym for an hour and kill myself trying to burn as many calories as humanly possible. Of course I was so sore for the rest of the week that I couldn't make myself get back there. So guess how long that lasted. Not long. Then it was back to riding the couch.
Generally, it's pretty hard to do something for the rest of your life that makes you miserable. Find something you enjoy. Something you'll look forward to. A walk, a hike, a bike ride. Maybe a zumba class or yoga.
Doesn't matter what it is, as long as you keep doing it. And that's how you'll burn the most calories.
