Wondering how to choose the right smart trainer? Here are some of the most common questions about the best smart trainers for triathletes.
What is a Smart Trainer and How Does It Work?
A smart trainer is a small, interactive bike trainer that mimics real-life hills, surfaces, and headwinds so the rider gets a realistic and well-rounded workout.
They come in a variety of different forms, so there’s something to suit everybody, every budget, and every space. Smart trainers use third-party apps to control their movements.
This gives the user a realistic riding experience, which is made even more real by the addition of video content that makes it feel like you’re riding through a forest or town.
What Types of Smart Trainers Are There?
There are two main types of smart trainers. The one you choose is up to you! They both do the same thing, but with slightly different mechanics.
Wheel-on trainers are just like they sound. You don’t need to remove your wheels at all. You simply attach your rear axle to a support and your back wheel rests on a roller to allow for movement.
The rollers are connected to a resistance unit. This unit can be controlled via your chosen app to provide an exciting riding experience.
If you choose a direct-drive trainer, you’ll need to remove your rear tire and connect your bike directly to the trainer.
These are generally more chunky than wheel-on trainers. They’re also often higher in price, but they’re sturdy and easy to use. You can do exactly the same thing whether you have a direct-drive or a wheel-on trainer.
Why Should I Train Indoors Rather Than Ride Outside?
Training outdoors is an excellent way to get some fresh air and a change of scenery. But it’s not always possible to be out and about, especially in today’s times!
Having an at-home trainer offers many advantages. For one, if the weather is bad you don’t need to skip a training session or spend an hour in the rain or cold outside.
It also offers an element of safety, especially if you only have time to train in the early hours or when it’s dark. No need to worry about reflective gear and self-defense products when you’re training in your own living room!
You can also train harder without the fear of traffic or exhaustion out in the open. This makes high-intensity sessions or training to exhaustion much easier to control and safer.
Using a smart trainer saves time too. It doesn’t take long to get your gear on and step into the bike when it’s ready and waiting for you. Make sure you buy a bike trainer mat to protect your floors.
Have you ever had one of those nights when you just can’t fall asleep? No need to lie around and be unproductive. You can get on your trainer and get in a great workout!
There’s also the added bonus of connecting with others online and being able to choose your scenery. You can even take part in national e-sports championships!
What Do You Need to Use a Smart Trainer?
If you want to use a smart trainer, you’ll need to invest in a couple of specific items. Obviously, you need a bike and a trainer!
Apart from those two, you’ll need a computer, a tablet, on a smartphone with your desired app on it. The device needs to have a Bluetooth or ANT+ connection and often a USB dongle is required too.
Good wifi is also important! If your signal is sketchy, you may find that using the trainer is more frustrating than anything as the picture lags or the movement of the bike doesn’t correspond to what you’re seeing on your app.
