Damage to those vessels can cause small strokes and memory loss. It’s not clear from this study whether the diet can actually lower the risk of stroke or brain damage, however.

Supplement Ingredient Scrutinized: Dietary supplements containing an ingredient called DMAA are the subject of a safety review by the U.S. Army and have been removed from stores on military bases following the heart-attack deaths of two soldiers during workouts, the New York Times reports . Toxicology reports say DMAA was present in the soldiers when they died, but whether it played a role in the deaths isn’t yet known. Supplement makers and retailer GNC say products containing DMAA are safe, while other experts claim it should be classified as a drug rather than a supplement. Image: iStockphoto

Breathing. You’re doing it right now without even thinking about it. Put a little thought into the action, and you just might find yourself soaring through your next tempo run . When you’re going the distance running, swimming, cycling, and even rowing you need to power your muscles with fresh oxygen . To do this, you need to breathe deeply. Unfortunately, most of us are just breathing into our chest and not fully utilizing our lungs. Cross-training with the noncardio workouts of yoga and Pilates can help. Along with strength and flexibility, these forms of mind-body exercise help you learn to breathe deeply and effectively. Basically, your lungs are just a bit smaller than your rib cage, but we all tend to breathe in just the top third of the lungs. One reason is that, like all muscles, the intercostals, which run between the ribs, can get tight and inflexible, limiting the expansiveness of your lungs. With a little training and some stretching, you can breathe to your full potential and increase your endurance. Learn a supersimple breathing exercise, simply read more.
