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.

pricey means of fiddle reduction
I have used many different timers on my smartphone over the years - they are fine but fiddly to use (unlock phone etc), and not 100% reliable - very annoying to unlock your phone wondering why your rest period feels so long, only for the timer to instantly chime as the app is de-hibernated by an unpredictable operating system, or an enforced update renders the app completely useless and you must set sail into the playstore for a replacement This chunky, matchbox-sized timer frees me from the shonky world of smartphones. I use it for 90sec rest period times, but it can be set up for a strict A/B duty-cycle as well.. Nice loud beep and buzz.. Just wish it had a session alarm as well so I don't have to use my phone at all.. Setting up is great - you just mash the SET button to smash through all the interval options and youre done Its a bit of a rip-off but it does seem nice and robust and well thought-out.. Its unusual for me to go for such a disproportionate function-to-price ratio, but the relief from buggy, laggy, fiddly smartphone irritation is worth it to improve focus

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!

Great Idea but need to improve the sensitivity of the buttons
I am using this timer to track my rest time between my sets in weighlifting so the idea to have two timers sets was brilliant. So I could track one of 30 seconds and then 90 for supersets. However, in this mode they do one after another and I I have to pause it. After the set sometimes your hands or arms are shaking, so tring to press its a bit difficult due to its sensitivity. An addedd problem is that you have to press 3 times the button to pause, making some times a desperate event of pausing it on time. I found at the end using the clock watch for the purpose, which I do believe at wrist one will be better.

A good buy.
Clear instructions and easy to setup. Robust construction. Easy to use control's even with running gloves on. Good tone volume. Securing clip works well. Over all a good purchase. Battery life seems good after a month of use.

It's an awesome product but it's in need of a subtle upgrade
I've been using this as a great alternative to my phones interval timer apps, which lets be honest can be a huge distraction when working out. The basic functions are ideal for me since i usually use them for cardio, boxing and stretching. Its an essential tool during training I can't go without. However, f you're looking for more diverse functions, you should probably look at one of the advance models like the miniMAX. The timer comes in a nice package with easy to read instructions and a a durable clip to put on your clothing. I do think that the price is a bit high, especially considering you have to purchase a separate strap to place on your wrist/arm. Overall i don't regret purchasing it when i did, it's a great investment and i'm sure you'll enjoy it too. With that said, it would be nice to see an updated version that has a built in rechargeable battery that could justify the price point.
