Exclusively for women, Curves is supported by women in the range of age 50 or older who begin to concern over changes in health or are either not good at or not experienced in exercise.
Curves workout is a circuit training that combines 'strength training', 'aerobic exercise', and 'stretching'. This unique program allows women to get all the exercise they need in 30 minutes, that has been scientifically proven to be effective through joint research with various research institutions.
Combining 3 exercises at one time are more effective more efficiently in shorter time than doing each separately.
Curves' customer base is mainly women over the age 50. Women are said to lose 1% of their muscle mass every year after 30, and its effects start to appear from around the late 40s. When you lose muscle, your metabolism lowers, making the body fat easily build up and harder to lose weight. The accumulation of visceral fat around the abdomen worsens health markers such as blood pressure and blood sugar levels, leading to develop chronic illness.
Muscle loss can also lead to pain in joints around the knees and hips. If left untreated, these conditions can increase the risk of life-threatening illnesses such as stroke and cardiac infarction, leading to being bedridden and nursing care.
If you go on extreme diet restrictions to lose weight, you would lose weight, but also muscle. This will lower basal metabolism and make the body more prone to gain weight. That's why the weight easily rebounds.
For women, muscle is necessary to build a body less likely to gain weight, and to prevent future illnesses and nursing care. Some people 'walk for their health', but walking (aerobic exercise) cannot build muscle while it burns fat. You need strength training to build muscle.
Curves' exercise program is designed to allow people who are 'not good at exercise' or 'older' to do strength training. In addition, combining aerobic exercise and stretching is designed to maximize the effects.
Curves will contribute to solving the problems of a super-aging society with an effective program to provide all the exercise necessary for women's health in 30 minutes and a system that encourages anyone to continue exercising.
