Because we’re focused on efficiency these days (isn’t everyone), be it gas mileage, or just time well spent, we’ve been doing speed laps at one of the local crags.  We get lots of mileage in this way and it doesn’t take much time.  The “game” goes like this: Climb for speed, rest equal amount of time climbing, repeat as necessary.  If you’re still not getting a workout, add a twenty pound weight vest, not only does it add to your weight, but it restricts your lung compacity too!  You’ll have a days worth of climbing in an hour or two and time to do other things!Click here to view the video
