Backstroke
The backstroke requires similar movements to the front crawl, but it is done, as the name suggests, on your back. Doctors often recommend this stroke to individuals with back problems as it provides a great back workout.
To perform the backstroke, while floating on your back, alternate your arms with a windmill-like motion to propel yourself backwards. Like the front crawl, your arms should start the circular motion by pushing underwater and recovering above water. Your legs should engage in a flutter kick. Your face should be above the surface as you look straight up.
Keep your body as straight as possible, with a slight decline in the lower body to keep your legs underwater. Don’t allow your hips to get too low or your body to bend too much or it will slow you down. Keep your legs close together and use the motion from your hips to get a more powerful kick.
Your face will remain out of the water, but you will still want to be cognizant of your breathing rhythm. Again, match your breaths to your strokes.
