GymbossPlus Interval Timer and Stopwatch - Black/Green Softcoat

Only a little larger than matchbook size and extremely lightweight I've found this to be the perfect tool for interval walk/runs. You WILL need to download a copy of the instructions off the web since I doubt even a NASA pilot can read them without use of the Hubble telescope. Not to worry--just enter "Gymboss instructions" in your favorite search engine and they'll pop right up. Though hard of hearing I use it in the beep only mode since the frequency is old age friendly and easily heard with the unit on your belt. The vibrate rocks and I might use it if the Gymboss is inside one of my pockets. Since it is small (and perfectly so) the clip doesn't extend past the unit thus you can't fully clip it on a 1 1/2" wide belt. It stays on fine nevertheless and on athletic shorts clips securely with no problem. Once you use it a couple of times the three-mode setup makes perfect sense and you can use it from memory. For intervals the unit is very versatile and gives you a lot of time and interval frequency options. Don't know yet how long the single AAA battery (not included) I put in will last but it says it has a low battery indicator so I'm not too concerned.

I've owned 2 gymboss timers. One bought in 2011 and one in 2013. I replaced with the Plus. (After 5 years use, the previous gymboss works but the lines that make up the digital numerals are missing in spots, so that an 8 looks the same as a 3 or a 4 - none of the numerals display correctly.) I tried rebooting, new battery and it didn't get wet, but it still remains that way.I'd recommend the Gymboss based on current and on past performance.-The Plus has a LOUD beep. I got it because the description said it's louder but "The beep can be made dimmer". I primarily use it in a loud "Sirius XM Pop Channels" (yuck) gym for weightlifting intervals. I can hear it with in-ear earbuds. I want the low beep for my quieter gym, and not disturb others. The low beep is still loud, BUT what I saw in one of the image views of the timer turned out to be true. It's NOT explained on the Gymboss website or in their expanded directions (which another reviewer, well said, said download the directions, the ones with the timer are a tiny font).There is a + or - slide on the back of the PLUS which I assumed to be the "dimmer" for sound. That makes the low beep better in a quieter, crowded gym. Push the slide to the (-) to cover up the baffles.If you're running outside, or lead a loud indoor group, the loud beep is good.- The loud beep is good for outdoor intervals. It can be heard. I remember that I had used the old Gymboss in the past for walk/run intervals, and could often not hear the beeps with other, street noise.- I'd prefer the Start button to be on the right side, as in my old Gymboss, but it's on the left, and I'll get used to it.- Vibrate mode has never worked for me. I can't feel it -- I always use it on an armband. The new model, however, feels a little stronger.- The loud beep has a "b" (lower case "b" display) and the quieter a "B". Opposite of what it should be.- Setup isn't hard, may get it wrong a few times at first, but you'll get used to changing intervals fast.- Tried using a smartphone Tabata timer instead of Gymboss. Not loud enough, not as simple to use and adjust, and I don't carry my smartphone in gym anyway. Gymboss is easy to set, start, track, and stop (if you don't want to hear 10 beeps for the finish of your session).I wanted the low beep for a quieter gym, and thought the Plus could be "dimmed" lower. Fully closed it seems lower, or at least the same as the base model. But since I may start using it outside again, I'll keep the Plus for that.

Love this little timer. Works great for intervals! Easy to set up

Great for interval training! I use this for my daily run/ walk intervals. It is loud enough to hear even with my music playing on my headphones so I don’t skip an interval. The only thing I do not like is the initial setup. Very confusing and tiny instruction manual. Google saved the day lol

I bought the GymBoss to help with my interval walking . It works well so far. The battery cover was pretty difficult to open. This is the only problem I have had

Nice quality, screen easy to see, easy to use, helps motivate you with whatever physical activity you are doing. Great for helping you to build endurance.

So far, so good. Easy to set multiple intervals and small but not too-small size with removable belt clip. Easy to set times and several lengths of alarm available. Uses common AAA battery. I wanted a vibrating watch but the choices and power were inadequate. This unit will serve multiple purposes from interval training to simply keeping me on schedule for numerous tasks. If it holds up, so will the 5-star review. Fast delivery to the convenient Amazon lockers I can walk to.

I needed a timer for a custom heavy bag boxing workout and this does all I needed it to do. I have not found any feature contrary to the provided description. It is small, maybe a little smaIler than a pager if you remember those. I did not find the setup or programming to be difficult at all. If you can set a digital watch...you should be good...no downloading of additional instructions needed. But if you struggle with a watch then maybe. I set mine for just 1 main interval of 1 min duration to repeat 30 times. I set the audible beep to be loud and 5 sec in duration. If you do hot need a 2nd interval you just leave that setting at 0:00 like I did. I take a break every 5th cycle running in place, or jumping rope then start the next round. Easy. My work out is printed out on the wall...I follow that. The timer just let's me know when to proceed. This would be great for weight training as well...I guess these days they call it "high intensity training" I've been doing that for decades...I called it "station training " 30 years ago and still do.... moving from one station or exercise to the next in a cycle alternating cardio and resistance. I will use this timer for that next.
