Waist–hip ratio
WHR is used as a measurement of obesity, which in turn is a possible indicator of other more serious health conditions. The WHO states that abdominal obesity is defined as a waist-hip ratio above 0.90 for males and above 0.85 for females, or a body mass index (BMI) above 30.0. The National Institute of Diabetes, Digestive and Kidney Diseases (NIDDK) states that women with waist-hip ratios of more than 0.8, and men with more than 1.0, are at increased health risk because of their fat distribution.
Weighted clothing
Thigh weights are the most reasonable form of resistance. The location of the mass more readily duplicates the natural fat-storage mechanism of the human body and being closer to the core. In leg raise exercises, it allows more activation of the hip flexors (and abdominals) without putting more strain on the quadriceps muscles for extension, making it good for sports-specific training on movements like knees and jumping. The greater area and safe location allow it to handle much more weight. For those with wide thighs, such as bodybuilders with large quadriceps, or people with large amounts of fat stores on the inner thigh, it may cause chafing. If worn on both legs, however, the chafing would be between the weights and only damage them, possibly only chafing with a lack of tightness.
