GYMBOSS SetupThe Gymboss Interval timer will be most effective if you take a few minutes to learn the setup procedure before you set out for your workout. It is really quite simple but does take a few minutes to learn, so we highly recommend you learn the setup procedure and the capabilities before using and you will find it very effective.
Instructions are included with the timer and a short cheat is printed on the back of the timer. Here are printable instructions as well.
