Adds structure to your workouts. Love this Gym Boss timer!
I've got quite into fitness in the last four months and as part of this do a circuit in my front yard 5 or so times a week. This little interval timer is vital to this as I'm working cardio and conditioning. I'm currently doing 45 x 30-second rounds with 8 second rest intervals between stations. Very easy to set round and interval durations plus number of rounds. Having the timer helps focus my intensity and means I know the whole thing will be finished in about 25 minutes - just get it done short and sharp and out of the way! The only thing I'd improve is increase the volume of the beep at the end of round and rest interval. With the music I play (using a little bluetooth speaker) it can get drowned out if the timer is on the ground. To solve this I clip the timer to my shorts using the built-in large clip. Stays in place no problem even if I'm skipping. If I'm working out with a family member I just tell them when a round ends and we move stations. I suppose if you want to work with headphones on you might have a problem hearing the beeps but that's not an issue for me. If the info is of use, the other main items I have bought from Amazon for the circuit are 'Cretee 12 in 1 foldable Push Up Rack Board Train Gym Fitness System Workout Exercise Stands for Body Training', 'Z ZELUS Battle Rope 12m with Anchor Strap Kit | 40ft Battling Rope with Protective Cover Carabiner and Anchor Set for Home Gym | 3.8cm' and ' Kitopa Dip Bars Station - Heavy Duty Dip Station, Dip Bars Adjustable, Parallel Bar 200 KG, Body Press Bar with Safety Connector', plus I also use various kettle bells and a skipping rope 'RDX Skipping Rope Wooden Handle Weighted, Adjustable 9FT long Leather Speed Jump Rope'. I'll try and get round and reviewing the other items but I'm happy enough with them to mention here.

Excellent item
Just what I was looking for, I needed a timer that had a controllable alarm. I dont use it for "Gym" purposes, I fly radio controlled planes and needed a timer to let me know when I had been flying for set periods. Until I found the Gym boss I had been using a stop watch, but that meant taking my eyes of the plane to look at the watch, tried kitchen timers, but the alarm keeps going on them until you stop it. With the Gym boss I can set the alarm to 1,2,5 or 9 beeps, it also has a low and high volume plus a vibrate setting which is ideal if I'm flying indoors with other flyers who have audible alarms. It also has a clock so I don't have to bother with a watch and a stop watch if needed. All functions work well and it is easy to use. The buttons are well designed, needing a firm push to make adjustments, you can put it in a pocket or hang on your belt without any danger of inadvertently changing the settings. Excellent item for anyone one wanting a timer with adjustable alarm. Well pleased.

Worth it
At first I didn't like it. Slightly frustrating, but once you get it right it's pretty good. The cycles of alarms were good too because you didn't have to stop and adjust it all the time. It just rolled into the next cycle. Less hassle. Thumbs 👍

Been using for a while, great bit of kit
Been using this for ages and forgot to leave a review Now part of my day to day gym kit. I use it for intervals, rest and reminding me to stretch for the full minute Best feature is for HIIT exercises, being able to program it for a set time to work, and a period of rest to follow, all on loop or for a set range of sets is really handy. Bit surprised more people aren't using them Also the beep is loud enough to hear whilst listening to headphones, and can change volume (two settings), or to vibrate instead

Brilliant - Endless Uses!!!!
I purchased this item after looking for a countdown timer watch that has a vibrate alarm but I ended up finding this which has proved to be even better. Small portable with a clip on option. It has 2 interval countdown timers, stop watch and clock with choice of combinations of vibrate and/or beep alarms for different lengths of time (1,2,5 & 9 seconds). This is mainly used for Gym Workouts but can be used for other purposes to regulate your time throughout the day. An absolute Gem!

Mines didn’t last long
Was great to use for interval training very easy instruction only thing is that mine has suddenly froze and I’ve tried taken the battery out resetting it and still it won’t start my timer I can switch options but can’t change anything nor get it to start at all which is a shame as it was good when it was working

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.
