We mentioned previously how much having an MMA gym timer for sparring, drills, and workouts help improve your training. The downside is many of them cost upwards of 70 dollars, some reaching almost 200 dollars.
I found a totally free fight timer, and it is absolutely amazing. You can set the round time, break time, number of intervals, warning time, sound effects, and much more. Of course, you need a computer wherever you are planning to use it. It’s great if you have a laptop, or you can hook your computer up to the sound system in the gym.
The link also includes special MP3 files, so you can load up your iPod with them. While not technically a functional timer, these files are special lengths, and you could do something like set the 5 min file on repeat, and essentially have an alarm for when you are working out.
