So I've decided to start cycling regularly to help get back into shape (I got slightly flabby over the summer) and I was wondering what a good routine would be. I plan to cycle just about every day after school, but am mystified as to how far/long to go to effectively burn fat. any help?

Want to burn fat/increase VO2 max? Tabata intervals.

You know what? I just tried biking around my house some, and the road has so many ups and downs that it's like murder. I think I'll try jogging around my property instead. Mods, feel free to delete this.

and thanks for the suggestion, cuban

Thought this was going to be about steroids.

With that attitude your never going to lose weight. No pain, no gain.

Y'know, I hear "sitting on the couch stuffing your face with potato chips" is an even lower-intensity exercise to burn those calories... ever try that?

OP is either a pussy, or a moron.

perfect setup ... hills and then rest on the downhill.
a nice interval situation (which may be the best method to de-flab).

Low level Jogging on your property can work too, but biking in your area sounds more promising.

Any exercises using your legs will work.
Do what you enjoy.
Try to get the effort level up to at least 30 minutes, 4x per week, is my suggestion.

I read it was something like 4 hours of bike riding, twice a week or sumshit..

Although i read this in some shitty tabloid newspaper the other week..

well, research it better, is my suggestion.
