How to Start Trainer Training — A Beginner's Guide

A first trainer session often ends in a puddle of sweat, boredom after 20 minutes, and the question "is this really supposed to feel like this?" It can be done better. Here's what's worth knowing before you get on the bike at home for the first time.

What gear to buy

Three categories to choose from: rollers, a wheel-on resistance trainer, and a smart trainer. They differ in price, noise and whether they measure power. You'll find a full comparison with a pros-and-cons table in our article on trainer vs rollers — if your budget allows it, a smart trainer makes getting started easier right away, because you see real power instead of guessing at intensity.

Setting up your space

• A trainer mat — protects the floor from sweat and vibration, and makes cleaning up easier. Details on when it's genuinely necessary in a separate article.
• A fan — without airflow like you'd get on the road, your body overheats much faster than outside. One of the most underrated purchases.
• Quieting things down — if you live in a block of flats, it's worth checking how to actually quiet a trainer before your neighbours start knocking.
• A phone or tablet — for your training app, at eye level, so you don't hunch over the bars.

The first few weeks — what not to do right away

The most common beginner mistake: the first session is straight into hard intervals, or an attempt to "ride out" as long as possible at full gas. The result — discouragement within a week, and muscle soreness that kills any desire for the next session.

• The first 2–3 weeks — easy riding at low-to-moderate intensity (Zone 2), 30–45 minutes, 2–3 times a week. The goal: get your body and your backside used to the trainer position, not build fitness.
• Shorter sessions more often — better than rare, long slogs. It's easier to build the habit.
• Only do an FTP test after 2–3 weeks — at the start you don't yet know your real capability, and you're not used to riding in place; an earlier test will come out low anyway. We covered how to do it properly in our guide to the FTP test and Ramp Test.

After your first FTP — what's next

Knowing your FTP is what lets you start training deliberately: power zones, ERG mode, a training plan matched to your real level. You can also check how your FTP per kilogram compares with other cyclists in our levels table.

The most common beginner mistakes

• Too much intensity from day one — leads to discouragement, not progress.
• No ventilation — overheating ends a workout faster than muscle fatigue does.
• Ignoring bike fit — same geometry as on the road, but without airflow and route variety, the load on the same pressure points is higher.
• Training with no plan — riding randomly "by feel" gets boring fast. Even a simple plan of 3 sessions a week gives a sense of progress.
