Trainers are interesting devices. These simulate an activity, and provide great exercise but without actually doing said activity. In other words a bicycle trainer lets you ride a bike and put in miles while you go nowhere. A cross-country ski machine needs no snow, and rowing machines need no water.
Keeping with the waterless concept the Vasa Trainer Pro is a swim simulator for those who don’t want to get wet – at least until you work up a sweat and then later hit the showers. It uses the same principal of a Nordic Track with pulleys and cables and your own body weight to provide the resistance.
You essentially lie on the bench and make the motion you could in the water, and used correctly you can get a good workout while helping your in-water performance. No swimsuit required.
