Indoor cycling guide: how to get started

Everyone wants to get faster on the bike, whether that’s to grab Strava KOMs, get fit for a sportive or shave some time off your ride to work – but what’s the best way to get yourself in shape?

In short, take your training indoors. While nothing beats the feeling of crushing your local climb or descending with the wind in your face, if you want to pedal like a pro, indoor training is the most efficient and effective way to get fit on two wheels.

“Anyone can benefit from indoor training, whether you’re new to cycling or an experienced racer,” says James Spragg of Spragg Cycle Coaching.

Let’s run through the benefits of indoor training and some of the workouts you can use to get fit.

What are the benefits of indoor cycling?

Indoor training is free from the distractions and external variables that come with riding on the road, including traffic, weather conditions and the suitability of your local terrain. There are no traffic lights to stop at, nor can you freewheel – indoor cycling sessions may only be short, but you’re making the most of every pedal stroke.

“You can constantly chip away at your fitness, even if you only have 30 or 60 minutes,” says Ian Jenner of Rule 5 Cycling Coaching, who advises complementing your weekend rides with two or three short, sharp indoor sessions.

Indoor cycling workouts

Intervals (repeated periods of focussed exercise followed by periods of recovery) are the name of the game, as far as indoor cycling is concerned, and prompt your body into making the physiological adaptations required to get fit. You can tailor the intensity of the intervals to work on specific areas of fitness. 

Training indoors also means you can get straight down to business, so you can truly make the most of every session. In fact, if you’re short on time, indoor cycling is your route to getting fit fast.

“You can perform every session exactly as planned,” adds Spragg. “There’s no need to waste time riding out to a specific stretch of road or a local climb.”

An interval workout will require you to judge your effort to ensure you’re working hard enough, without overdoing it or blowing up before the end of the session. It’s a tricky balance, so you can use Rate of Perceived Exertion (RPE), heart rate or power to help you.

Rate of Perceived Exertion (RPE)

RPE refers to a sliding scale to gauge the intensity of exercise. It’s the simplest way to judge whether you’re pedalling too hard or too easy, without needing additional gadgets to measure your heart rate or power output. 

RPE is simply a measure of how hard you feel you are working, rated from one (sitting on the sofa doing nothing) to ten (100% sprint to the line). The higher the number, the less time your body will be able to remain at that intensity. British Cycling has the full RPE scale on its website.

Heart rate 

A heart rate monitor adds an element of scientific data to your training. That means you can closely monitor your riding intensity in order to pace your efforts, as well as targeting heart rate ‘zones’ to achieve specific training benefits.

There are two types of heart rate monitor: a strap that fixes around your chest to measure your beats per minute as blood is pumped from your heart, or a watch that measure your pulse from your wrist. Generally the former is more reliable. Either way, using a heart rate monitor is the easiest and most affordable way to dive a little deeper into your training.


Power meters are all the rage with experienced cyclists and measure the watts produced when you stamp on the pedals. Power is the most accurate and reliable measure of your performance and, if you’re serious about your training, allows you to closely target very specific physiological adaptations.

You can attach a power meter to your bike (crank, pedal and wheel-based units are available) but, for indoor cycling, the latest smart turbo trainers and interactive training bikes also come equipped with built-in power meters.

You can ride Zwift with a conventional turbo trainer, a smart turbo trainer or a dedicated indoor training bike 

The latest training apps (including Zwift) provide simple tests to help you measure your baseline power, as well as a wide range of interval workouts to get the most out of every session. Zwift’s virtual worlds also let you ride alongside thousands of other cyclists.

What do you need to get started?

If you want to train on the bike from the comfort of your own home, you have two options. You can either mount your regular road bike on a turbo trainer, or you can use a dedicated indoor training bike like the Wattbike Atom.

In recent years (and as we’ve already alluded to) we’ve seen the rise of smart trainers, which come equipped with the internal electronics required to directly measure your power output. They can also automatically control the resistance when paired with training apps like Zwift, TrainerRoad and The Sufferfest.

You can also use these apps with a conventional turbo trainer, but you’ll normally need an ANT+ or Bluetooth speed sensor on your bike to communicate with your smartphone, tablet or computer. Conventional trainers can’t measure your power output directly or automatically control the resistance (you’ll need to use your bike’s gears for that), but they are significantly cheaper than smart trainers.
