Stopwatches are fine if you’re timing simple stuff. But when it comes to interval training or multi-exercise workout routines you really need a dedicated interval timer. This allows you to set a work interval, plus a rest interval, of two different times. Look no further then the Gymboss. Hit Amazon to save a few bucks. I personally went with the new slightly ‘rubberized’ version which is a bit more durable then the standard plastic shell.
