This article by Men’s Fitness.com says so:

Mom always said to take your vitamins. But she didn't mean overdo it. Thirty-five percent of adults swallow a multivitamin on a regular basis, but several studies warn that an abundance of extra nutrients may not be as good for the body as previously suspected. Just check out the data.

DIABETES: While vitamin K and thiamine appear to help reduce risk factors, scientists warn that selenium in vitamins may increase the risk of type-2 diabetes.

PROSTATE CANCER: Too many multis may increase your risk of developing a form of fatal prostate cancer, according to data from the National Cancer Institute.

LUNG DISEASE: Multivitamins don't protect against lung cancer, say scientists at the University of Washington. (In fact, too much vitamin E may increase the risk.)

LONGEVITIY: Perhaps most alarmingly, vitamin supplements may increase your overall mortality risk. So says a recent Danish review of 67 studies involving more than 200,000 participants. After analyzing the data, researchers found that people taking vitamins were 4% more likely to die during the course of the study than people who weren't taking them. Yikes.

THE BOTTOM LINE: If your diet sucks, a multi may help. But if you already eat well
and buy fortified cereals and breads, you're likely getting all the nutrients you need.

Interesting. Like most Americans who believe that they’re taking an active role in their health, I ingest a multivitamin on a daily basis (and actually, I take them on a nightly basis). But I don’t know if this article is enough to scare me away from taking them every day.

I wish the article had provided more detail as to the appropriate amount of times a week it’s okay to take a multivitamin. Based on that last paragraph, the article would almost lead you to believe that you should take a multivitamin on the days you can’t eat as healthy as you should.

Low testosterone levels may boost the risk of fractures for men over 60, an Australian study finds.

The researchers tracked 609 men (average age 72.6) between 1989 and late 2005.

The University of Sydney researchers collected information about the men's bone mineral density, lifestyle habits, and blood levels of testosterone and estradiol (an estrogen).

During the study period, 113 men suffered low-trauma fractures (caused by a fall from standing height or lower). Of those men, 25 suffered multiple fractures.

There were a total of 149 fractures, including 55 vertebral, 27 hip, 28 rib, six wrist and 16 upper- and 17 lower-extremity fractures.

The risk of fracture was much higher among men with low testosterone levels, the team found.

Even after adjusting for a variety of potential risk factors, low blood levels of the two hormones "were associated with overall fracture risk," the study authors concluded. Fracture risk was associated "particularly with hip and non-vertebral fractures," they noted.

The findings are published in the Jan. 14 issue of the journal Archives of Internal Medicine.

Vitacost.com's Daily Health Tip

Men’s Fitness.com shows you how to perform the neutral-grip bench press to boost your gains on the bench.

The strongest, smartest lifters don't bench-press with their upper arms 90 degrees from their sides. They tuck their elbows in on the descent to get more power and reduce the risk of shoulder injury. Performing the neutral-grip bench press for eight to 12 weeks will help you get comfortable with the technique.

1) Grab dumbbells and lie back on a bench. Squeeze your shoulder blades down and together and arch your lower back. Position the weights at the sides of your chest with palms facing each other.

2) Press the weights straight overhead, keeping your wrists in the same position.

Why It Works
Pressing with the palms facing each other, rather than pointed toward your feet, will naturally cause you to keep your elbows close. Soon, you'll do it with the barbell, too. This takes excess pressure off your shoulder joints and increases your mechanical advantage, allowing you to lift significantly more weight.

Men’s Fitness.com details an easy way to strengthen your ankles for when you’re doing plenty of outdoor running this summer:

Problem: Tight calves and a weak tibialis anterior muscle (the one next to the front of your shin) are two of the most common causes of ankle injuries.

Solution: Ankle circles, which can stretch your ankles and strengthen your tibialis. Lie down, grab the back of one knee, and pull your leg to your chest. Begin making circles with your foot. Do 20 to 40 clockwise and then repeat the opposite way. Do these every day and strive for more circles at each session. Increase the effectiveness of the exercise by using a foam roller on your calves beforehand.

While it may seem too simple to be effective, ankle circles will make a difference right away. By bringing your tibialis into balance, you'll increase the potential for your calves to get stronger and boost the stability of the joint, lessening the likelihood that your ankles will roll out on you when playing basketball or any other vigorous sport.

I once had a girlfriend that asked me if I would train her if she signed up at my gym. Since she hadn’t exercised in years, I was generally excited that she was taking an interest in her health again and that she had asked me for help.

After two or three training sessions and one massive fight later, we never worked out again. That was also the last time I figure to help a lady friend out at the gym, but if you’re look for better luck than I had, Men’s Fitness.com offers these exercise tips for couples that want to work out together.

1.) Forget your own training.
"If you're trying to show off by demonstrating how much you can lift, you're going to have problems," says Rachel Cosgrove, a strength and conditioning coach and co-owner of Results Fitness in Santa Clarita, Calif. "She wants you to pay attention to her." This means concentrating on moves that she can do and enjoy (unless you want a dumbbell dropped on your foot).

2.) Say the right things.
Feed her compliments-and try to ensure that she processes them as such. "Don't say, 'Wow, your arms are getting so big,' or, 'You're looking really buff!'" says Cosgrove. "If a woman hears that, she might never come back with you to the gym." Instead, reinforce her work by telling her that her arms are really "toned," or that her legs are "defined."

3.) Know what she wants.
Her goals are to burn calories and fat, and get more "shapely." So take it easy on the isolation exercises, use lighter weights and higher reps, and keep her moving. "Women are multitaskers," says Cosgrove. "They want combination exercises, compound movements, and circuit sets." In terms of body parts, she's concerned with her legs, glutes, and-most of all-abs. "As much as guys love the bench press, that's how much women love ab work," says Joe Stankowski, a trainer of pageant contestants in Wilmington, Del. So grab a Swiss ball and crunch!

4.) Disguise the workout.
Women often fear weights, so hide weight training in moves like medicine-ball squats and med-ball overhead presses. You can also use those colored, plastic kettlebells for figure eights and swings. And here are always cable moves like wood chops. She will find these exercises more fun and less intimidating, and she won't feel like she's turning into the Incredible Hulkette.
