MP3 Timer that keeps time for me so I can do what I do best

I like using my gymboss during class and workouts but I constantly have to keep my eye on the timer, which can take away from me watching my members workout. Then there are the instances where I have to keep an eye on the timer to say "half way" if I want members to switch sides.

One thing that I like to do to switch things up is use a MP3 called workout muse. They have a lot of different time schemes (some of my favorites are 20/10, 30/30, and the 30 second ladder). Then the MP3 which I downloaded onto my phone can be used and tells the members how many rounds they have done, a coundown to when to start, when to stop, and even when they are halfway.

If you go to the website, click on the "Music Store" then click on the "interval programs" tab and check the "free" box. Some sample workout programs will show up for you to download. You only have to set up an account and don’t even need to provide credit card information to download the free MP3s.

Some examples are the 60-15 Spartacus workout (Complete) Zip File.

Most of the actual downloads range from $97 (for a ton of different themes) to $13.95.
