What are you going to do

More than 10 percent of the world’s population is now obese, a marked rise over the last 30 years that is leading to widespread health problems and millions of premature deaths, according to a new study, the most comprehensive research done on the subject.

Published Monday in The New England Journal of Medicine, the study showed that the problem had swept the globe, including regions that have historically had food shortages, like Africa.

Why calorie counting is almost useless and often misleading

Petros Giannakouris / AP
“A new study says taking a hot bath burns as many calories as a 30-minute walk.”

That popped up in a tweet from Time on Tuesday night. It referred to a small investigation into the physiologic effects of heat exposure.

The responses on social media were an inevitable, exultant mix of self-identification and self-deprecation. Things like, This is so meeeeee, and Guess I’m right for not going to the gym, suckers, and Fill ’er up (the tub) I’m taking a bath forever and going to eat the whole time [gluttonous emoji].

And, of course, This is a distraction from the Russia scandal.

We are all constantly projecting meaning onto the world to suit the templates we’ve committed to, so I saw the study’s finding as an indictment of calories. My own reply was that the study serves to prove that calories are “an almost useless and often misleading metric.”

My tweet was popular and beloved by almost everyone. Read more Cindy + Box Jumps

I Did 30 Burpees For 15 Days and Here’s What Happened

They’ve been called the most efficient exercise known to humankind, and doing them every single day was more rewarding than I could have imagined.

When I wanted to try CrossFit, I dragged one of my best friends to a beginner’s class with me. And although she was a good sport about it, she mentioned on our drive home how the deadlifts-crunches-burpees circuit would have been so much better had it been just deadlifts and crunches.
I was shocked. To me, the burpees were the best part. It was then that I realized not everyone is as crazy as I am—not everyone enjoys burpees. This got me thinking: What if I incorporated burpees into my daily routine?

I did some digging into the origin of the exercise, and I found out they were created in 1939 by a man named Royal H. Burpee to determine a person’s physical fitness. Back then, the move didn’t include a pushup in the middle or the jump at the end, but it was still dreaded.

First, I wanted to make sure my form was on point. I decided to do the modern burpee, not the old-school version from the 1930s.

I read some how-tos. To do a burpee, start from a standing position, then squat down and place your hands on the floor in front of you. Quickly kick both feet out behind you so you are in a pushup position, and then do one pushup. Next, bring your legs forward to go into a squatting position again, and jump up.

Yes, it’s an awkward, frog-like movement. But I knew it would be worth it to challenge myself.

I’ll admit I’m not great at sticking to things. I always have the best intentions, but when life starts to get busy, I’ve been known to make excuses here and there (I’m working on it, I swear). I was glad I had this story to hold me accountable as I set out to become a burpees beast.

So with my trusted 50 Cent Pandora station by my side, I got to work.

Here’s what I did:
I completed three sets of 10 burpees for 15 days straight. I started out with a one-minute rest in between my sets and decreased that time by 15 seconds every three days until I was doing all 30 burpees at once with no rest for the last three days.

I wanted to stick to the same time every day—when I woke up at 7:30 a.m.—but that didn’t always work out. When I slept in, I’d do a circuit when I got home at around 4 p.m.

Here’s what happened: 

1. My running improved.
My typical easy pace is about nine minutes per mile, but towards the end of the 15 days, I started running faster without consciously ramping up my speed. My lungs felt clear and I coasted through miles.

I was also going longer. I’ll Read more I Still Hate Burpees

Why Exercise Is Good for the Heart

Even a single workout could be good for the heart. That’s the conclusion of a fascinating new study in mice that found that 30 minutes on a treadmill affects gene activity within cardiac cells in ways that, over the long haul, could slow the aging of the animals’ hearts.

Although the study involved mice,the results may help to explain just how, at a cellular level, exercise improves heart health in people as well.

There’s no question that, in general, physical activity is good for hearts. Many studies have found that people who regularly exercise are much less likely to develop or die from cardiac disease than people who are sedentary.

Still, researchers have remained puzzled about just how exercise alters hearts for the better. Exercise is known to improve our blood pressure, pulse rate and cholesterol profiles, all of which are associated with better cardiac health.

But many scientists who study the links between exercise and heart health have pointed out that these changes, considered together, explain only about half of the reported statistical reductions in cardiac disease and death.

Other, more complex physiological modifications must simultaneously be taking place within the heart itself during and after exercise, these researchers have speculated.
