Gymboss Review

May 21, 2010

What is this?
The Gymboss is a small, easy-to-use, dual-mode, interval timer.
What do I use it for?
It can be used for a large variety of training-protocols where time is an important variable. I’ve tested it for HIIT and weight training.
Test number one: HIIT: 15 s sprint/45 s walking x 10.
For this protocol, I set the first timer to 15 seconds and the other one to 45 seconds. Once the timers reaches zero, the device either vibrates or gives off a beeping sound. I prefer to set it to vibrate since I have my earphones on during training. I set it to be repeated ten times. 15 sec, buzz, 45 sec, buzz, and repeat.
Test number two: 4 x 4 squats (6RM), 55 s per set/4 min rest x 4.

First, I want to say thank you for convincing me to do Tabata! I was struggling to lose weight and Finally I found something that helped! I really appreciate your coaching! - Craig T.

Ever since I was convinced to do Tabata I have seen huge results, I lost 6 pounds and gained energy in the first 3 weeks. I have been working out for 3 months before I decided to do Tabata and I struggled to lose weight. At first I thought "How am I losing weight by bringing my heart rate up then cooling down then bringing it up again?" I don’t know how it works but it does! Thank you!! - Theresa F.

The first day of Tabata, I wondered WHAT AM I DOING - I AM 56 !! Five weeks later I knew that it was what I needed. I learned that I could push myself well beyond my comfort zone and feel good later. I have a marked improvement in physical as well as emotional endurance. - Lyn C.

When I was first told about Tabata I was very excited from the word go, however that excitement stemmed from the fact that I had no clue what it meant. I missed the first week of class b/c I was traveling for work so when I came in during the 2nd week I had some making it up to do. It was hard at first b/c my body wasn't used to working out at such a fast pace, but once I got into a rhythm I started to feel very good. These classes are no joke. If you stick with it you will leave there feeling stronger, healthier and overall better about yourself and what you've accomplished. I would recommend these classes to anyone. Darrin is a great trainer and he'll keep you going with his energy. - Jami L.
