>> This is Michael Kanellos at News dot com trying the compex eight ninety-nine compex sport trainer. As you can see, it can be painful the first couple times you use it. But it's making me sweat with a barrier of 4 seconds to 7 seconds. But you can build up and tease up those old fibers you're not using.
>> So we have different programs and tradition you run some distance strengths which you're likely recording. Let's say you want to a resistance and then you have, these are the battery. Shows the batteries here on the field, the time of the program, you go with the upper limbs or down limbs, and then you have five different levels okay?
>> And these are the electrodes that get attached to your body?
>> We have the small ones and the big ones, you'll see now okay?
>> So now we are going to track.
>> Great, excellent.
>> So that should be rounded to you, slide out right? Big muscles and the medialis making nice muscles here?
>> So and let's go a little bit and look what's gonna happen if I.
>> It's kind of a white tingling going on, the electrodes.
>> Look at your muscle?
>> Oh yeah it's twitching.
>> We start at level one and then we say start. It's then asking me, okay bring out those basic. [ laughter ] That's it.
>> My legs immediately began to tingle.
>> Now put your legs in the same position.
>> Okay? I'm going to bring you now into contractions.
>> What's going on here, the contact sport is stimulating nerves in my legs and making my muscles flex. This helps them actually get more muscle into any kind of thing you're doing. Alputo Tomba used it in the 1988 Olympics to train for that and a lot of soccer teams use this too. [ cheering ] ^m00:01:59
>> Oh my God! I didn't expect that.
>> I know, I know. Look what happened to you.
>> Well my Lord look at that! Takes a little getting used to.
>> You have to get used to the feel, to feel that you're lingering. And you're gonna feel it going. Stretch it! Stretch it! Stretch it! ^m00:02:44
>> 4, 5, 6, 7. Here it comes, okay.
>> 49 seconds of workout with a very high intensity.
>> In 29 seconds I can get your heart out.
>> You see again? You're working on one muscle, especially the high biceps right here, the triceps are working because of you? Look these are triceps. And somehow go back to, feel pain, is it pain? That's so fantastic because we test our techniques and try as close as possible to the.
>> Yeah, with the high energy.
>> High intensity.
>> Seven year olds four seconds each, that's 28 seconds of work out here.
>> Ahh! [ laughter ]
>> For people who are injured, for people who has positive trainers all the time it's a pretty good deal. I'm Michael Kanellos with News dot com.
