Dr. Schwartz says the average American is eating at least two to three times the recommended daily amount of sodium, and most don't realize it. That's because most sodium isn't coming from the kitchen salt shaker. About 80 percent of consumed salt comes from foods that are processed, canned or purchased in restaurants.

The best way to reduce sodium intake is to eat more fresh foods and less canned and processed foods. Other sodium-reducing tips include:

Cut back on eating in restaurants, especially fast-food restaurants. Use unsalted spices in cooking, for example, garlic powder instead of garlic salt. Rinse canned vegetables to remove sodium. Check grocery labels for sodium content and opt for those products with low sodium.

Budget Friendly Fitness: Tips to Break a Sweat Without Breaking the Bank

A health club membership isn't a prerequisite for staying in shape. The September issue of Mayo Clinic Women's HealthSource offers suggestions on free and low-cost options to help stay in shape without straining the budget.

Buy used equipment: Some sporting good stores specialize in used equipment. Great deals can be found online too. But be aware that shipping costs might put the cost out of budget range. Shoppers should be cautious about responding to ads, since scams abound.

Buy affordable equipment (or make your own): Hand weights are reasonably priced, available in many sizes, and can be used to strengthen every muscle group. Home-improvised versions work well too. Milk jugs or water bottles filled with varying levels of water or sand work well as weights. (Secure the tops with duct tape.)

Check out the local recreation department: Many community recreation centers offer discounted fitness classes to local residents. High school or college fitness centers or swimming pools also may be open to community members.

Use exercise DVDs: Practice aerobics, yoga, strength training and tai chi with DVDs. They are available to buy or rent. Libraries are a good source, too.

Share costs with a friend: Trade exercise DVDs with a friend. Find a personal trainer who is open to you sharing sessions with a friend or two.

Know what to avoid: Some fitness products aren't worth buying, no matter how low the price. Avoid products that offer instant fitness benefits or promise to melt away pounds without diet and exercise. Avoid products that focus on one body part, such as abs or thighs.

Make the most of everyday activities: Walking, gardening, taking the stairs, and playing with children or grandchildren offer free fitness benefits.
