Remember the difference a good pair of wraps/gloves made on training gains? This Gym Timer is up there with said discoveries.Now $130 seems like a lot of money for something an iPhone/iPad could replicate. Au contraire. This bad boy is durable, so darn easy to program, and loud enough to overcome any music/fan noise accompanying it. No more midget screens I can't hear. It's also the perfect size to be noticeable without being cumbersome.Some might criticize this timer's lack of options...but that's exactly why I like it. Program your rounds, a rest period, and let it fly. 30/10 seconds left reminders, double beeps at start/round conclusion. Be creative with round lengths and rests to enable differing conditioning drills. When unplugged (which I do when not in use = no on/off button) it remembers previous settings.What it isn't? A CrossFit/TABATA timer. There are limitations to round/rest intervals. Still, with a little bit of creativity, this can arguably serve such a purpose.If you're a serious boxer/fighter...serious about his/her training...this needs to be on the top of the list for initial purchases. Maybe I'm just old school, but there's something so beautifully simple about a proper boxing timer to make the rounds and sweat fly by.
