How might a person use technology to improve her workout

There is a scientific study that music can help the rhythm or strides a person has while working out. There are many fitness watches; which can calculate the number of steps you took, distance you ran, your heart rate, etc. I (personally) have used fitness apps to help consider what I should do for a workout, as in, what would most be a benefit to me and my body type. 

Some of this is from personally experience, as I am on a cross country team and use technology for my workouts in day to day life. 

I hope this helped you!

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.
