It's amazing how much technology has gone into these different types of fitness gadgets and fitness equipment. I remember when the only exercise gadget you used was a watch with a second hand. My boyfriend in high school was on the track team and his parents bought him a running watch for his birthday. He was so excited because he could time his runs.
Today, when I go into a work-out center exercise room, I feel like I should have a special degree or special certification to operate the exercise machines.
