Listen up, slackers: You can no longer use 'work' as an excuse to avoid burning calories during the week. It turns out, you could get your best workout in over the weekend, without lifting a finger Monday through Friday.

According to a recent study, cramming all of your weekly exercise recommendations (or goals) into one or two weekend sessions is just as good as working out during the week, and yields the same significant health benefits. Experts say staying active over the weekend was still enough to reduce the risk of early mortality by a third. 

The observational findings — published in JAMA...

If anyone embodies the ideals of healthy living and longevity, it appears there's no one better suited for the role than Robert Marchand.

He's been doing all the right things for quite awhile now; eating well, exercising frequently and steering clear of dangerous habits. And as a result, despite his advancing age, there's little to slow him down – including an hour-long bike ride.

Which broke a world record.

At the age of ... 105.

To those who know him, the indefatigable Frenchman once again demonstrated that adhering to the tenets of good health pays off handsomely, this time with a ride of slightly more than 14 miles in 60 minutes, the longest ever for anyone his age. The 5-foot centenarian accomplished the feat at the Velodrome National, France's top...

I can burn how many calories while shoveling?  You don't have to resolve to hit the gym this month, especially if you can easily burn 200-400 calories while doing winter outdoor activities: skiing, snowshoeing, and even shoveling.

A recent health story is currently making the rounds proclaiming that some forms of exercise, as well as participation in three particular racquet sports, are better than others for your overall health and will help you live longer.

These online articles invariably attract our attention. Why? Because they carry headlines that provide the simple solution that everyone craves: the way to better fitness, and finally, a clear, unambiguous and athletic path to a long, healthy life.

Sure, these stories do contain some worthwhile information on how to improve one's fitness. But unfortunately, they are the very definition of health hype.

That's because placing emphasis on specific activities is overblown, and the study these stories are based on has a range of...

Last week I wrote about exercise and the young — now I want to go to the other end of the age spectrum and provide some evidence that not only is physical activity good for older folks, it can even help with rehabilitation.

A major downside to aging for many people is loss of independent mobility. For example, having to be bedridden for an extended period can  make it difficult for a person to regain the ability to walk as independently as they might have done previous to their illness. This disability can negatively influence  a person's quality of life, and increase the probability of depression and social isolation.

The question of how best to help such individuals regain...

We all know aerobic exercise (e.g. running, swimming, walking briskly) is good for the heart, and apparently it's also good for the brain. Of course, if one neglects to keep up with the activity, fitness declines. Dr. J. Carson Smith from the University of Maryland in College Park and colleagues wanted to know what happens to the brains of older folks who exercised vigorously and often if they stopped exercising. The report of their study was published in the journal Frontiers in Aging Neuroscience. In particular, they investigated what would happen to the blood flow to two parts of the brain — the overall cerebrum (controls voluntary actions, emotions, etc.) and the hippocampus (area under...

It’s pretty widely known that chronic over-indulgence in alcoholic beverages can play havoc with one’s liver — in extreme cases ending up with cirrhosis and a non-functioning organ. But non-drinkers can also have liver problems. In particular, there is one called non-alcoholic fatty liver disease, or NAFLD, which is a risk factor for chronic liver disease and cardiovascular disease, according to the authors of a recent...

Here's a Nintendo-owned augmented reality game that doesn't require sitting on the couch. In fact, you have to walk to play it, and it's taken the U.S. by storm. Pokémon Go encourages players to find and 'catch' Pokémons by taking a walk in the real world and getting some exercise to boot. Pretty genius, if you ask us.

Screen Shot 2015-11-05 at 1.08.33 PMIn today's "Let's Try to Reformulate Coca Cola and See What Happens" contest, we may have a winner: Prescribing stimulant drugs to people who are too lazy to exercise, so that they become less lazy and exercise more.

Yep, it's true. An article in ScienceDaily discusses just such a suggestion, which came from an endurance expert at the University of Kent in the United Kingdom.

MRI-strokeThe current JAMA has two articles on Alzheimer's disease that evaluate simple interventions, in hopes of maintaining age-appropriate cognitive functioning among two groups of older Americans. One study evaluated the efficacy of increasing seniors' physical activity to inhibit mental decline; the other evaluated omega-3 fatty acid plus vitamin supplementation for that same goal. Unfortunately, neither intervention showed any significant benefit.

In the first study,...
