Useful timing device for exercises
This little device is very useful for timing sets of exercises. You can set the number of reps you want to do, and how long of an interval you want to rest between, and it will buzz to tell you when to stop/start each repetition and will also buzz for a longer time to let you know when you have completed all the reps. Easy to use.

Great Interval Timer(s)
Works as intended. Once you learn the controls, it is easy to use! The vibrate function is great can be used alone or with the beep. I personally use this not for working out, but to remind me regularly all day to get up & move around / change positions (I have chronic pain that improves if I do). It also reminds me to stay focused on tasks I need to do. It's wearable, so I never lose it! Very useful!

Great Timer which Revitalized My Workout! A Real Motivator.
I've only had this a couple of weeks but absolutely love this. I've nick named it "The Motivator" I've been walking, jogging and doing push -ups for about 5 years now. I'm 59 years old and am very routine oriented. I've read about interval training and have always wanted to do sprints and walk but have had some concern and hesitation. Although I do not have any knee problems I just didn't know if my body could handle it. Anyway a few weeks ago I decided to try it. So when at the park I had no time keeper but tried to count 15 seconds while sprinting and 1 minute rest and repeated. After this one lap of that I walked a few laps. I felt so good and invigorated. The next two day's when I went back to the park I did my usual 2 lap walk then did 2 laps of sprints and walk and a final lap of walking (3 mile total). This is fantastic but I know I needed a time keeper, so I looked here on Amazon and found this Gymboss Interval timer. This timer comes with very good instructions to teach how to set it up and use. I absolutely love it. In the few weeks I've adjusted my sprint time from 12 to now 15 seconds keeping the one minute rest. I've also increased the amount of sprints I do in total. This timer actually is motivating me. I can't wait to get back to the park to do my exercise. It has helped to revitalize my workout routine. It's giving me goals to attain and makes my workout fun. It is very light in weight yet feels sturdy. It has a very strong clip with good grab. I clasp it onto my shorts and feel confident that it won't fall off. The audible beeping or vibrate modes (or both at the same time) work very well for the interval training. It is also a stopwatch which I use during my walking laps, and a clock. Great price for all the value it has brought to my workout. Wish I would've gotten this years ago. I highly recommend this timer to anyone looking to revitalize their workout or who just wants a sturdy multi-functional timer.

Awesome for interval training, a little hard to set the times intially
If you do any sort of tabata or HIIT workouts, you need a gymboss, it will change your world. When I do HIIT workouts on a spin bike, I don't want to count in my head or have to keep looking at a clock on a wall or starting/stopping a timer. Enter gymboss! Set the interval times - exercise time and rest time - clip on to your waist and it will tell you exactly when to start and stop. You can set it to beep and/or vibrate at each switch from exercise to rest time and for how long it beeps/vibrates. If you're in a crowded gym or working out next to someone, I'd recommended turning off the sound, it will annoy people. Love this, lets you really dig into the workout and concentrate on giving full effort w/o having to think about keeping track of time. Very convenient - easy to throw in gym bag and very small and light, comes in cool colors. It's a little bit annoying to set all the times and settings you want, but I tend to use the same number for a couple weeks so it's fine.

Good Timer, But Sticky Residue Ruins It Over Time
I really like the Gym Boss timer itself—it’s durable, versatile, and works great for interval training. However, after about a year of use, the body of the timer develops an annoying sticky residue that’s extremely hard to clean. I’m not sure if the coating is breaking down or what, but it feels like a molasses-like film that even shows fingerprint impressions. I use these in a commercial gym setting, and the residue is unpleasant enough that I often grab one and then look for an alternative just to avoid the sticky mess. I’ve even bought replacements after this issue appears, which is frustrating because the timer itself is solid. If the manufacturer could fix this coating problem, it would be an easy 5-star product. Until then, I can only give it 3 stars

Got this for getting back into running to set up walk/run intervals. I'm no longer wear a watch and didn't want to carry my phone or strap it to my arm. Also my phone does not have the specific functionality of this little device where you can set up two intervals of different times as well as a specific number of repeats. I considered getting the wrist or arm band but after reading other reviews decided not to and I really don't think I'd find any benefit in either of them. The Gymboss is just the right size to hold comfortably in my palm, but also clips very securely to any piece of clothing. The clip has a good "grabber" on it so it's not going to fall off even while running. I liked the different volume levels and vibrate option so I can made adjustments if my running environment is noisy (ie city traffic) or quiet (trails). Setup was simple and easy to understand. This device does exactly what it should, no more and no less, making it the perfect purpose built interval timer. I would buy it again without hesitation.
