Gym Boss Timer

For the past couple of months I have been using a Gym Boss Timer to keep track of rest periods for myself and clients. I wasn't sure about it at first I had read about it on another website and decided to check it out. It has helped to decrease the amount of time I spend in the gym and is providing a better workout. It also works great for interval training, which can be difficult to do using an ordinary timer. I highly recommend getting yourself one if you don't already have one. If you are interested in getting one go to gymboss.com.
