WFOB is the only reason I exercise! They have an amazing team of instructors (I typically take classes with Julie, Dawn, Debbie, Quincy, and Angela) who actually make working out fun - I am most certainly the type of person that needs to be tricked into exercising so I take the group classes. My favorites are pilloxing and tabata. The location is convenient and the prices are so reasonable (with lots of employer discounts). The gym itself has everything you might need - group classes, fitness equipment, showers, lockers, etc.

Focus on the long term. Diets fail when people fall back into poor eating habits; maintaining weight loss over the long term is exceedingly difficult. Most people regain the weight they've lost. In fact, some studies indicate that 90 to 95 percent of all dieters regain some or all of the weight originally lost within five years. Your program should include plans for ongoing weight maintenance, involving diet, exercise and a behavioral component. While there are some physical reasons for obesity, there are also behavioral reasons for excessive eating. For example, many women use food as a source of comfort (perhaps to deal with stress). For these women, a weight loss program with a behavioral component will offer alternatives to replace food in this role.

Nutrition-sensitive approaches are difficult to link to women's nutritional status (5, 102). This is due to limited measurement of benefits to program beneficiaries, families, households, and communities, limited timeframes to evaluate long-term impact, logistical and political realities that make implementation difficult, and different priorities of different stakeholders in multisectoral programs (102). Many nutrition-sensitive approaches, as will be described, thus focus on more distal measures of impact (e.g., coverage, knowledge) and not more proximal measures of women's nutritional status (e.g., BMI, anemia status, etc.).
