I asked the question here on desertcart and no one responded, so I'm assuming nobody else has needed to do this (or has figured it out). The instructions indicate you should just go into your saved program, change it to however you want it, and then save it. But it's not that simple, and I exchanged at least a dozen emails or more with the company before realizing how I needed to change it. They were responsive about answering my question in a timely way, but their responses didn't clear up the confusion. So after a bunch of emailing, I had pretty much given up on being able to change an existing saved program. And there is only room on the device for about 20 different saved programs, so you wouldn't want to have to keep creating new ones as you changed your mind about a workout. So here are the details of what I needed to do and how I did it: Let's say you have saved a workout in the Multi category and it has 7 different intervals. Then you change your mind and want to eliminate interval 4 so you'll only have 6 intervals. You can't go into the saved workout and delete interval 4. There is no delete option on this device. Also, the device won't let you set interval 4 to last zero seconds. I tried that and the minimum number of seconds it will allow is 2 seconds. So I thought the best I could do is have a bogus interval 4 that lasted 2 seconds which I would have to ignore. The critical piece of missing information that nobody mentions is that you have to go into the saved workout and RE-ENTER EACH INTERVAL FROM THE BEGINNING TO THE END. If you re-enter each interval, you can make intervals 1, 2, and 3 the way you want them, then you make interval 4 look like the old interval 5 looked, and you make interval 5 look like the old 6 looked, and the final interval CAN be brought down to zero seconds. And then you can save it that way and you have essentially deleted interval 4. When you re-save a workout, it overlays the previous version of that workout, so you won't be wasting one of your 20 on a useless workout. I guess I could have rated this unit less than 5 stars because of the terrible instructions and the less-than-helpful email responses, but the unit itself is really great. So I decided to rate it based on that instead. And as others have said here, be sure to print the official instructions you can get from the gymboss website rather than trying to use the terrible instructions that will ship with the unit. Armed with the official instructions and the information I listed above, you should be able to figure out how to enter and update some great workout interval programs. Review: All I have to do is press start - My old stopwatch bit the dust. On it I was able to program an interval and the number of Reps for my daily exercises. I was unable to replace the Watch with another that would do the same thing. Instead I used the interval notice app on desertcart Echo until that stopped working. Then I resorted to manual Counting trying to keep track of intervals and number of reps in my mind. then one day I thought of using the search criteria of exercise timer on desertcart. I came across the gymboss products. I saw that the second level product would do what my old stopwatch did. I immediately ordered the second level gymboss. a bit later I looked at the Minimax gymboss and saw its potential. I immediately cancelled the original order and ordered a Minimax. When it arrived I spent a bit of time using the materials sent with it and the directions that I found online to do the programming for my exercise routines. I was able to program multiple exercises with different intervals and numbers of reps. As the Minimax allows storage of that program as well as leaving it active, it's always there for me when I start my routine. All I have to do is press the start button. I am absolutely delighted with the Minimax. I can't imagine going back 2 my old stopwatch where I had to program each routine with each interval and each number reps. Do I wish there were some other features on the Minimax? Yes. For example I wish the beep at the end of a rep was a single beep rather than the double beep. I suppose the double beep is better for a noisy environment but my environment is quiet. I also wish there was the ability to program a different tone at the end of a routine. But all considered I love this little machine. It's so much easier than my old stopwatch where I had to program each routine with its interval and number of reps. All I have to do is press start ## Features - The miniMAX is an advanced model, designed for timing extremely complex interval programs consisting of more than 2 different intervals. If your program only has 1 or 2 different intervals you DO NOT NEED THIS MODEL. Due to the nature of complex intervals this timer is harder to setup than the Classic or Plus model Gymboss and requires more patience to learn how to use it. If you do purchase this model, we do have printable, expanded instructions on our website help page. - Compact, advanced interval timer tracks up to 25 different intervals between two seconds and 99 minutes. Save up to 20 programs. - Built-in Stopwatch and Clock features. Secure and Removable Belt-clip included. - Chime and vibration interval notification; alarm duration can be set for one, two, five, or nine seconds. - Compact size powered by one AAA battery (not included); measures 2.25 by 1.75 by 0.5 inches (55mm X 44mm X 14mm).

Can I set the watch to sound alarm for each portion of the sequence?** A: Yes. You can set a small beep, a big beep, and/or vibration. You can also set how long it beeps. I sometimes do a 5 part workout with 20 seconds each and then go into a 90 second break. For my workout, I set it to give me one small beep for each 20 second section and then 2 big beeps for the 90 second break. **Q: Does the timer reset itself? if set it at ten second intervals?** A: On the MiniMax, you can set it to repeat 10 second intervals (or any other intervals) up to 2,475 times. At the end of the number of intervals you set, stops and you can start the whole thing over again with the press of one button. **Q: Can this be set to Just vibrate - no sound? I need an alarm set for every 30 minutes that will not annoy everyone around me.** A: Yes, it can. You can set the miniMAX to vibrate for 1 second, 2 seconds or 5 seconds. ## Customer Reviews ### ⭐⭐⭐⭐⭐ How to delete intervals on this device - not intuitive! *by D***P on August 9, 2014* I love this interval timer, but it was an absolute chore to figure out how to change a saved program once I had entered it and then later changed my mind and wanted to update it and save again.

I'm a trainer and have been using the gymboss for over 10 years. It's great for interval training and mma/boxing. It has a rubber coating for grip and protection in case you drop it. It's conveniently small, the controls are intuitive, and very durable. ## Frequently Bought Together - Gymboss miniMAX Interval Timer and Stopwatch - Black/Yellow SOFTCOAT - Gymboss Interval Timer and Stopwatch Watch Strap – Black - Gymboss miniMAX Interval Timer and Stopwatch - Green/Yellow SOFTCOAT --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/262240-gymboss-minimax-interval-timer-and-stopwatch-black-yellow](https://www.desertcart.pl/products/262240-gymboss-minimax-interval-timer-and-stopwatch-black-yellow) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-30*
