Hong Kong clothing brand Shanghai Tang's design concept is inspired by Chinese clothing and set out to rejuvenate Chinese fashion of the 1920s and 30s, with a modern twist of the 21st century and its usage of bright colours.
The elementary backstroke is one of the simplest swimming strokes that you can do on your back. You do not burn as many calories as a more intense form of the backstroke, but you keep your face above water the entire time.
Variables: Intensity, Weight and Time. The amount of calories that you burn when swimming this stroke will depend a lot on the intensity that you put forth, how much you weigh, and the amount of time that you swim. The more you weigh and the harder that you swim, the higher the amount of calories you will burn doing the elementary backstroke. A 120-pound person swimming an easy pace will burn 120 to 220 calories in 30 minutes. A 200-pound person swimming at a vigorous pace will burn 200 to 400 calories in 30 minutes.
