Love them or hate them, turbo trainers can be considered an essential piece of kit for training, particularly through Winter during bad weather and dark nights. As useful as they are, however, there's sometimes no getting away from the fact that they can be quite boring, with nothing but the four walls of your room to look at whilst pedalling away. The introduction of the Smart turbo trainer has then been a godsend for countless cyclists as they can make training indoors not only more realistic, but more importantly, more fun. A smart turbo trainer differs from a standard trainer in that it can be used with interactive programs such as Zwift or TrainerRoad to enable you to feel like you're riding an actual route, with climbs and descents. These programs feed back to the smart trainer, adding more resistance when climbing and less whilst descending to create more of a simulated road bike feel than a standard trainer or rollers. Additional components can be added to the smart trainer to further enhance the realism, such as gradient simulators to improve the impression of climbing, and fans to simluate headwinds. Smart turbo trainers can be paired with other training aids such as heart rate monitors and power meters to give realtime read-outs on the screen, to fully optimise your training routine.
