lilTanker saidexercise doesn't reduce your life span.. regular cardiovascular exercise as we resistance based helps promote better hormonal balance within your body, promot feelings of wellness, burns calories.
Resistance based exercise (weights) is great for building bone density ( you should be having a minimum of 1200g of calcium every day and not taken with caffeine which inhibits calcium absorption) and promotes muscular development
I didn't mean that exercise reduces longevity, I meant in excess it may.
I was referring to things like the CRON-diet, based on studies that suggest reduced caloric intake and moderate exercise force the body to slow down and not age as rapidly. It's suggested it may be an evolutionary coping mechanism, relating to how we can survive food shortages long enough to perpetuate the species.
I concur that exercise in the right amount is crucial, since people who exercise have lower resting heart rates, which is good for health ;).
