Let’s pretend for a second that you’re a Western cowboy about to face off in a duel. But the problem is that you’re in deep shit because I just handed you a six-shot Magnum and said “you have to duel with a blind fold on while the other guy doesn’t”. How likely are you to succeed and come out of this situation ALIVE?

There is no point pondering, you’re a guaranteed dead man (or woman). The point is that you can’t shoot for something without having a goal in mind. You can have the biggest, most bad ass weapon ever, but it’s utterly useless if you can’t aim it in the direction you want. Well guess what cowboy? The same concept applies when it comes to fitness. If you want to have a body that commands respect, you need a clearly laid out GOAL… otherwise you might as well workout blind. I’m serious.

So how do we “aim” in terms of fitness? Well the first step is have a goal, but the second step is to TRACK your shit. And I mean track everything you can, from the reps, sets, rest time etc. The more info you have the better because then you can visually SEE whether you’re on the course to greatness or about to fall off into a ditch. In fact if you track properly, corrections can be made well ahead of time and save you grief, unlike others that end up in situations that are extremely difficult to get out of. This is when they come to me.

So to help you track your stuff, enter GYMBOSS Interval Timer. It’s a massive leap beyond an ordinary stopwatch and has got some nifty features under it’s belt. Before we get all naughty with the product, let’s hear the official description…

First Impressions:

The first thing you’ll notice is that the product is actually a LOT smaller than it’s made out to be on the pictures you see around the net’ (and you guys thought it was only the people on Myspace that had deceiving pics). In any case, it was a pleasant surprise. The timer itself is built like a rock and has sturdy buttons that provide a satisfying “CLICK” feel when depressed.


It comes in adequate packaging and has clear instructions in the manual. There are also basic instructions on the back of the unit, and this was a good call by Gymboss because it takes a few usages for you to get completely used to it’s UI and navigation. As for the product itself, I got the silver one but they also have a pink one and a black (“slate”) color available. DSC09939

As you can see it’s got a host of features. I specially like the water and shock resistant aspect because when you’re in the gym… shit can hit the fan (or your timer). So let’s put it to the test.

Real World Results:

Now as I mentioned earlier, it’s not the most intuitive thing in the world to use. But that doesn’t mean it’s difficult either… it’s in the middle of the pack. In my first few workout sessions I found myself having to turn the unit over for the basic instructions and after fooling around it for a few minutes I was back on track. It features 3 buttons: “Next” “Change” and “Start”. You program the functions using a combination of the three.


Here’s how the GYMBOSS differs from a normal run-of-the-mill stopwatch: Let’s say you want to do 4 sets of squats for 8 reps and you know that with a tempo of 5 seconds per rep you will spend a total of 40 seconds per set. Plus a few extra seconds (around 5) will be used here and there when you need to get adjusted.

Now since you’re lifting some heavy shit (you should be if you’re able) you might want to rest for a minute and a half between each of your 4 sets. So you set the # of intervals to 4, set the initial time to 30, and set the secondary time to 1:20. Then all you do is press “start” and go. As soon as you finish your set, it will go “beep” and your rest period will start, you don’t have to look at a clock to guess. Then after your rest period is complete, it will “beep” again so you can start your second set. It’s like having a trainer telling you when to go.  DSC09948

The cool thing is that you can have it “alert” you in three different ways. You can either have it beep low (BL), beep high (BH), vibrate (V) or beep AND vibrate (BLV). I think this is fucking fantastic because it has allowed me to use the GYMBOSS in the quieter areas of the gym where a loud “beep” would come across as a little disturbing. Personally I found the best option during busy times is the beep+vibrate option. Ladies, this thing is better than a phone in your crotch pocket. Oh yes, I went there.DSC09946

Another way that you can use the GYMBOSS is by using the manual mode (Man). Let’s take the same squat example above, but this time we’ll assume that you aren’t sure of how many sets you want to perform because you’re tired or [enter another lame excuse here]. What you do is set up the intervals in the same way but instead of setting the auto function to a certain number, you leave it on “Man” mode. In this mode, the GYMBOSS will take care of your rest period and time under tension individually. When you’re ready to start the next set, YOU have to press start instead of the GYMBOSS going continuously. Prime!

Shock Test

I ended up performing two types of shock tests for the GYMBOSS. The first was an accidental one because I was trying to set it up while wearing the GRIPADS and it just dropped outta my hand. Oopse.

But the second one was more, uh… scientific. The stair drop. It was as simple as it sounds… turn on the GYMBOSS, toss it down the stairs and check to see if it still works. Well it did. Check the video below for stair tumbling goodness.

Water Test

I was actually nervous about this one… not because I wasn’t confident about it’s build quality, but because the way it’s assembled. It’s physically solid but on the sides there are minor gaps between the casing. It doesn’t seem super air tight, but fuck it… testing is testing and I gota do what needs to be done. So I turned it on, and poured a cup full of water all over it. Thank god it survived and is still working. More wet proof in the video below.

Grip Test

The unit comes with a clip that has two “teeth” which act as anchors and attach to your belt, pants etc. and it never once fell off. I used it while weight lifting, kick boxing, mild jogging and advanced plyometrics. In each of these situations the GYMBOSS held on tight. Nice.



So the interface takes a few tries to get used to but after using it a few times I’m sure you’ll get the hang of it. It’s really not rocket science and trust me, programming those old ass VCRs was much more difficult. It’s also built like a damn brick (albeit a tiny brick) and will survive almost anything you throw at it.

There are also no faults in it’s functionality because it does what it’s supposed to and if you’re someone who practices any form of intensity training (and you SHOULD) then this thing will keep you on the right track. It’s also fascinating to note that since I’ve been using the GYMBOSS, I’ve been leaving the gym faster than usual because all my workout and rest periods were accurate to the second. Before I used to just look at clock and this ended up wasting a minute or two of my time. It may not seem like much but when a few minutes are wasted every set… it tends to add up and I don’t know about you, but I want to get the hell OUT of the gym ASAP.

So the only remaining factor is the price. Well fortunately it’s nothing out of this world and for twenty bucks, I think it’s a pretty good deal. I mean, there are “sport watches” out there that cost $40+ and can’t do what the GYMBOSS can. The only people who I can see NOT benefiting from this device are the ones that goto the gym aimless… lifting the same shit day in and day out. But those people need much more than a solid interval timer to help their situation. Overall, it comes highly recommended and therefore it gets my…

  1. I just ordered one today (the black one) and I can not wait to get it in. I have seen a few people using it and it looks like a tool any one that works out should have.

    Great review for an awesome little device, which I certainly would be without anymore for doing tabata intervals with my beloved kettlebells
