Editor's Notes

April 04, 2019:

High intensity interval training is one of the best ways to lose weight and increase cardio endurance. In order to do it effectively though, you need a timer to keep track of your rounds. If you are looking for something you can mount on the wall at a commercial or home gym, the GymNext Flex, Synergee Premium, BTBSign CFT023 are ideal options. They all have displays large and bright enough that a whole room full of people can see them. Most can double as a clock too when not being used as a timer. Those who need something to keep themselves in check when they are exercising outdoors or by themselves at the gym will be better of with something small that can be easily carried, like the Gymboss Plus, Honmax 8200, Leap TF6204, which, depending on the model, can be worn like a watch or clipped to your clothes. Speaking of a watch, if you'd rather forgo a traditional timer altogether, you can get the Casio STL-S110H-1BCF. The Seiko S057 is great for coaches who will be training other athletes, and the FCXJTU Digital YS391 is suitable for somebody who works at in a spare bedroom at home and wants something that can place anywhere on the floor.
