Indoor training is a great way to improve your fitness. By removing both bad weather and traffic from the equation it allows you to focus on the session with little or no distraction.
Fitting it around a busy schedule is easy too. You can essentially train night or day, and if even you're short on time a 30-minute cycling workout at a high intensity will pay dividends.
Indoor cycling also ideal for those new to cycling, allowing you to get used to efforts out of the saddle, clipping in and out of the pedals, and generally becoming at one with your bike, all from the safety of your home.
Training indoors is pretty ‘faff free’ too, but there are some vital pieces of kit you’ll need to get started. We’ve compiled a list of everything required to begin training as well as some additional items and upgrades you’ll want to add to your indoor set-up once you become more confident. To cater for a range of budgets, we’ve included a budget option and a more expensive choice.
Wheel-on turbo trainer
Halfords Turbo Trainer
To begin cycling indoors you’ll need to choose a turbo trainer. After all, you won’t get far without one.
There’s a huge choice when it comes to the best smart turbo trainers and navigating this crowded marketplace might seem daunting. However, to get started you don’t need to spend a fortune.
An entry-level wheel-on turbo trainer is a pretty straightforward affair. It is usually built around a folding A-frame design, with your bike attached to the trainer via a quick release mechanism on the rear wheel, which is then in contact with a roller to produce the resistance required to simulate riding outdoors.
The cheaper wheel-on trainers use magnetic resistance, which can then be adjusted via a lever that you attach to the handlebars.
If you spend a little more money you’ll be able to enjoy fluid resistance. This system uses a blade or propeller inside a liquid-filled chamber to produce gradual resistance, allowing the changing of your bike’s gears to impact the level of resistance. Spending considerably more takes you into the world of direct drive trainers, and we've an entire page dedicated to comparing wheel-on versus direct drive turbo trainers.
If you want to use one of the best indoor training apps, such as Zwift or Rouvy, with a wheel-on trainer you’ll need to check its connectivity as well as likely having to buy a speed and cadence sensor, which we will feature later in this article...
There are a couple of other considerations too. While a wheel-on trainer keeps your bike intact it does mean that your rear tyre, in contact with the roller, will wear as your train. It’s certainly advisable to invest in a dedicated turbo trainer tyre (not for use outdoors!) and to save you having to do a tyre change before every indoor session it also makes sense to set up the training tyre on a rear wheel you’ll use just for the turbo - see below for our choice of training tyres.
Finally if your bike uses disc brakes and as a result thru-axles you’ll need to check compatibility with any wheel-on turbo trainer before you buy. It’s highly likely that you’ll need to purchase an adapter, so make sure to figure this into your budget.

Indoor training tyre
Van Rysel Turbo Trainer Tyre
A wheel-on turbo trainer is a great way to start indoor training. They are affordable and relatively straightforward to set-up. However, as previously mentioned the mechanics of the trainer has your rear tyre in contact with a roller or cylinder. The compound of many regular road tyres will wear quickly during these indoor sessions, making a dedicated turbo tyre a smart, and cost effective, solution.
A turbo tyre is far more durable, is designed not to over heat and has tread pattern created specifically to provide better grip on the roller - but remember these tyres are not to be ridden outside!
Setting up a spare wheel with a turbo tyre allows you to swap it in before each session and is relatively hassle-free when compared to changing a tyre every time you want to ride indoors.

LifeLine Speed and Cadence Sensors
If you want to follow an indoor cycling training plan you’ll ideally need to be able to judge and track your efforts. While more expensive smart trainers have the necessary technology integrated into the unit, a cheaper ‘traditional’ turbo trainer will likely require you to purchase some additional tech.
By adding a speed and cadence sensor to your bike you’ll be able to accurately record both of these metrics. Thanks to bluetooth or ANT+ technology the sensors pair and connect wirelessly to any compatible bike computer, tablet or smartphone.
The sensors are simple to install, attached to the bike's wheel hub and crank arm.

LifeLine Training Mat
Training indoors is often focussed around interval training, with a series of high intensity efforts that really get the heart rate going. Another result of such efforts is sweat. And lots of it.
We’ll get on to cooling fans in a moment, but a training mat helps protect your carpet, rug or floor from drops, or perhaps pools, of sweat. It also helps prevent damage from the turbo itself, caused by dragging it into place or by the feet moving during a session.
Cheaper trainers, while usually portable, aren't always the most solid and secure and dedicated rubber training mat can really improve the stability of your set-up. Equally, a training mat can also dampen vibrations, making the turbo a little quieter than perhaps otherwise - a bonus if you live with other people!

Honeywell HT900E fan
Even if your indoor training in reality has your ‘outside’ in the garage or garden shed, the hard efforts mean you’ll build up plenty of sweat as your body tries to cool you down. Unlike riding outdoors, where the air helps evaporate the sweat, indoors it has no place to go. And the longer the sweat remains on the body, the more you in turn sweat, which then thickens the blood. As a result your heart has to work harder.
All of which is a long winding way of saying you need to invest in a fan. Naturally there are dedicated turbo training fans, some of which can be paired with a smart trainer. However, if you’re just trying to keep cool during an indoor training session then there are a number of general purpose fans that will fit the bill and don’t cost the earth.
There are some downsides here; most of these cheaper fans are manually operated so you’ll need to switch it on before you hop on the turbo. This means you’ll be hit with a blast of cold air before you've worked up a sweat. And it will be a blast. The majority of these fans will need to be cranked up to 10 if they are to offer any sustained help. That said, they work and are an ideal choice for those just starting out in their indoor training journey.

Indoor training jersey
Rapha Indoor Training T-shirt
We won’t pretend that you need any specific indoor cycling clothing for an indoor training session. Essentially you can wear gym clothing or any cycling jersey or base layer and shorts that you’d use outside; if you have some dedicated hot weather kit this should be a good match for the turbo as it’s likely to use lightweight and highly breathable fabrics.
That said, if you’re committed to indoor training, there are a few training jerseys and t-shirts made specifically for the purpose. Because of the issues with sweat build discussed in the fan section, indoor cycling tops are focussed on wicking moisture away from the skin. They’re also likely to be cut slightly differently from a regular cycling jersey, tending to be a little looser to help promote airflow.
The more expensive options tend to have a full zip and more closely resemble something you might wear on the road, whereas cheaper designs look more like a gym t-shirt or vest.

Indoor training shorts
As with the jersey, you can wear a pair of summer bibs when you’re training without suffering any reduction in performance. But like the dedicated training jerseys, a pair of indoor training shorts offer a number of benefits that could lead to a more comfortable session.
Many training shorts are just that, losing the bib straps associated with traditional cycling shorts. While bibs are more comfortable over the long distances you’re likely to cycle on the road, a session on the turbo is shorter and more intense and additional fabric against the skin is likely only to be an annoyance.
In fact, given they are used for much shorter periods of time Indoor training shorts tend to stripped back in general, with little need for much more than breathable and flexible fabric and a pad that suited to the requirements - again moisture management and quick-drying are key here, with gel inserts and the like unnecessary.

Indoor training shoes
Reasons to buy
Reasons to avoid
Indoor training shoes too are a stripped-back affair. As with the jersey and shorts, breathability and moisture-management is key here. To achieve this, and promote airflow, many shoes will use a sock-like mesh upper, which your foot slips in and out, with adjustment likely to come from a simple velcro strap rather than a dial or laces.
