365 Ways #344–Mother Nature knows her physics

#344--Crunches won't give you a six-pack. Even if you can perform this entirely dysfunctional movement for 30 minutes at your target heart rate, there's no such thing as spot reduction. In general, we get thin from our fingertips and toes in, so abdominal fat is typically the last to go. I know you think that's a shame. But we wouldn't be here if that process were reversed. If our ancestors stored fat in their extremities, it would have dramatically increased the energy cost of movement. The farther a weight is from the fulcrum the more strength is required to move it. So running away from danger or chasing after food is a lot easier if the ten little piggies at the ends of your feet don't all have pot bellies.
