Fitness is a measure of human being's healthy status. With more and more come out of poverty today, people pursue fit lives through various ways such as reasonable nutrition, regular exercise and sufficient sleep. Fitness is improving through smart wearables more and more popularly with the prevalence of Internet of Things and smart phones. There are various smart wearables such smart glasses, smart wristbands, smart watches, smart gloves, smart clothes, smart hats and smart shoes, etc. Typically, these smart wearables form a personal area network (PAN) based on Bluetooth around a smart phone. In this survey, we studied the underlying technologies for smart wearables from hardware such as sensors, actuators and microcontrollers to software such as operating systems, apps and cloud, etc. that are available in the consumer market. At the end, we look into the future directions such as implantable biosensors and challenges such as privacy and security of smart wearables for fitness.
