GymBoss

If you’re serious about your workout, and have even been looking for an interval timer that would help you get the best results out of your workout, I think you should take a look at GymBoss.

It is a tiny timer that you can clip-on, signaling you about the end of a duration by beeping, vibrating, or both, so that you can shift to the other end of your intensity workout. GymBoss can even be used as a stopwatch.

I took shots of the box, which also has some explanation on the back of it. GymBoss comes in three colors (Silver, Slate Gray, and Hot Pink) and sells for $19.95, but what is really great is the flat cost of ground international shipping, which is $2.99 almost anywhere in the world.
