...Published in the Aug. 13 issue of the New England Journal of Medicine, the study is the largest and longest of its kind to date. University of Pennsylvania researchers recruited 141 breast-cancer patients with a diagnosis of stable lymphedema. Half of them participated in a biweekly 90-min. weight-lifting program, which involved the slow, progressive addition of weight machines and free weights, up to as much weight as patients could comfortably lift; the other half of the patients did not lift weights at all.

...yearlong study, the women who worked out were stronger than the non-weight lifters - some could bench-press as much as 85 lb., while the majority were able to press dumbbells weighing more than 15 lb. - and did not experience any more swelling than the nonlifting group. Indeed, the exercisers were more likely to report that their symptoms had improved, with half as many (14%) reporting flare-ups as their counterparts (29%). Fewer flare-ups, doctors say, means less physical therapy to treat them - which means considerable savings in patients' time, money and discomfort. (Watch a video about fitness gadgets...
Although some previous research had hinted at similar benefits of weight training, the overall lack of rigorous evidence to support it led doctors to take a conservative approach in recommending excess activity. "Because we didn't have strong data one way or another, there was this dictum that translated to, Don't lift anything, or only minimally use your arm," explains Dr. Brian Lawenda, a breast-cancer-radiation specialist at Naval Medical Center San Diego, who was not involved in the new study...

Like all other Trikkes, it lets you generate momentum by simply shifting your weight on the thing's wishbone platform. The side-to-side motion, which feels similar to carving your way down a ski slope, is what propels...
...study's authors compared medical data from 1998 and 2006 and found that obese Americans--who now make up a quarter of the U.S. population--are responsible for a $40 billion jump in annual medical spending. Obese people spend $1,400 more a year than people of normal weight on medical services, according to research data. Medicare doles out $600 more for obese beneficiaries; Medicaid pays $230 more for their prescription drugs. Annual costs associated with obesity are now estimated at $147 billion and are growing nearly 9% per year. The report attributes the spike to treatment for obesity-related...
