“Obesity shaves two to four years off the average lifespan, …
while being very obese can shorten your lifespan by 8 to 10 years…” on par with life expectancy reductions of a heavy smoker.
Here’s some quick math for proof:Suppose your resting heart rate is 70 beats per minute (bpM). At 70 bpM your heart beats (70x60x24x365=) 36,792,000 beats per year (bpY). But suppose instead, we reduce your resting heart rate just two (2) bpM to 68. This, in turn reduces your bpY to (68x60x24x365=) 31,536,000bpY.
Now, if you really want to track to the nat’s ass, go ahead and take out the three (3) 40 minute cardio exercise events per week (165x40x3x52=) 1,029,600 bpY it will take to get and keep you fit enough to maintain this bpM condition.
At 68 bpM (instead of 70), you’re now banking almost 2 months of heart beats each year … or an additional 4 years of heart beats over the the next 24. And if you started at 72 (which would be low for an obese person), that’s 8 years!
So, while I regularly rant on the need for consistent resistance training to look and feel terrific, a complete fitness program also includes 60 to 120+ minutes ofcardio work each week.
