Well Ive had my Gymboss Interval Timer for a few days now, have to say I love it.

It is simple to use, and has a clip on the back so you can clip it onto your workout clothes. This week I have used it to perform tabatas as well as circuit training.

The beep is loud enough to hear over my ipod, so I still get to listen to my music working out. My girls commented that they could hear it beeping when I was outside and they were in the house ! (the patio doors were open though)

I was thinking about what intervals I could use this for, you can set it to run with 2 different times, and up to 99 sets, so there are endless possibilities.

1. Tababtas (work 20 secs rest 10 secs repeat x 8 )

2. Circuits - you can programme the timer to whatever you like, I set it to 1 minute and 20 sets. I just went from 1 exercise to the next no rest.

3. We run a Martial Arts school, and they do sparring, so we can use it for the 3 minute rounds with 1 minute rest for 5 sets. (Dont think they will like us for this one) Whats great is that once you get the timer set up, and press start you dont have to touch it again, great if you have your bag gloves on.

4. I was thinking about my friend who is learning to run, well, she can set it to run for a couple of minutes and then it can beep for the walking phase.

5. Finally I will be able to run my intervals outside, I always avoided it as I hated having to look at the stopwatch. With this after the warm up, I can press start and then sprint for a minute and then recover for 3-4 minutes.

This tiny piece of equipment really has endless possibilities, it really was the best $20 I have spent in a long while.

It is so versatile, as you can programme it so many ways.

If any of you already use it, let me know some of your workouts.
