    Some people think going to the gym takes time and effort, it often hurts, and it can be extremely boring.Most weight-related exercises are a combination of sets and reps(几次几组).In order to see any significant change from any one exercise,it will probably need to be repeated six to eight times, for a minimum of three sets, for about three months: Then there' s aerobics(有氧运动).For some, there's nothing more boring than endless miles spent running on a treadmill(跑步机).

But what if there is a way to reduce the boredom of exercise while still getting a good workout? Luckily for us, there’s virtual reality (VR).

“In the past, playing video games was a sedentary(久坐不动的) experience:,"says Jo Stauffer of the VR Heaitn-institute, but VR changes all of that.” Many, VR games are played while standing In order to play properly, the players are forced to move around swinging their arms or using their legs.After an hour of this on a regular enough basis, it's not surprising, that many people unexpectedly find themselves a little fitter .There are already a number of virtual reality games which, deliberately or not, result in their player “getting a good sweat on” if played for enough time.For example, there's a music game which forces players to shadow box(做空拳攻防练习) in order to hit the notes---that's an upper-body workout.

The benefit of VR has been noticed by one company.They want to take the whole experience into the gym. They are making a resistance machine, designed to be used in combination with a VR headset. Players challenge a virtual competitor in a series of games,which results in a 30-minute full-body workout.However, the cost of the equipment is expensive and there are safety concerns to be worked out, says J.P.Gownder from the consultancy Forrester.

Although it's early days, for those: of us who struggle to overcome the boredom of exercise,a new solution could be coming.And a world where a person can exercise and have fun at the same time might be something that many people would want-virtual or not.So don' t give up exercising.
