How to Structure a Warm-Up for Indoor Cycling Sessions

The warm-up is one of the most misunderstood parts of an indoor cycling session. Too often it is treated as a casual spin, a chance to settle in, or worse, something to be rushed through so the “real work” can begin. In reality, the warm-up plays a critical role in how safe, effective, and enjoyable the rest of the session will be.
For indoor cycling instructors, a warm-up should be deliberate, progressive, and clearly linked to the aim of the session.
This article outlines how to structure a warm-up properly, and why each part matters.

What a warm-up is actually for

A warm-up has three primary purposes:

To prepare the body physiologically for harder work

To prepare the nervous system for the demands of cadence and resistance changes

To prepare riders mentally for the session they are about to complete

If a warm-up fails in any of these areas, instructors often spend the rest of the class compensating for it. Riders struggle with technique, intensity feels erratic, and fatigue arrives earlier than it should.

1. Start controlled, not casual

A warm-up should begin with light resistance, a steady cadence, and a seated position.
This initial phase is about gradually increasing muscle temperature and blood flow, improving joint mobility, and easing the cardiovascular system into work. Starting too hard does not “wake people up” faster. It simply places stress on cold muscles and spikes heart rate before the aerobic system has properly engaged.
At this stage, effort should feel comfortable. Riders should be able to focus on how they feel on the bike and settle into a smooth pedal stroke.

2. Progress intensity in small, deliberate steps

Intensity must rise gradually throughout the warm-up.
This can be achieved through:

Small increases in resistance

Controlled changes in cadence

Short combinations of both

What matters is that changes are predictable and progressive. Large or sudden jumps in effort early in the session can lead to premature fatigue without delivering the benefits a warm-up is meant to provide.
From a physiological perspective, gradual progression allows heart rate, breathing, and muscle recruitment patterns to adjust safely. From a coaching perspective, it builds trust. Riders feel guided rather than caught out.

3. Introduce cadence changes early

Cadence changes are a key part of an effective warm-up and should not be left until the main body of the session.
Changing leg speed prepares the neuromuscular system, improving coordination and control. It also gives instructors an opportunity to observe how riders move on the bike before intensity becomes more demanding.
This is particularly important in indoor cycling, where cadence can vary widely depending on the style of session being delivered. Riders who are not exposed to cadence changes early often struggle later, especially under load.

4. Coach technique while load is low

The warm-up is the safest and most effective time to coach technique.
When resistance and intensity are low, riders have more mental capacity to process instruction. This is the ideal moment to reinforce:

Posture and body position

Smooth, controlled pedalling

Appropriate resistance choices

Trying to correct technique once riders are already working hard is far less effective and can increase the risk of poor movement patterns being reinforced under fatigue.

5. Align the warm-up with the session aim

A warm-up should never be generic.
The way you prepare riders should reflect what they are about to do. A strength-focused session requires a different warm-up to a speed-based or endurance session. Cadence ranges, resistance choices, and progression should all point towards the demands of the main body.
This also helps riders understand the purpose of the session. When riders know what is coming, they pace themselves better and engage more confidently with the work.

How a warm-up should finish

A well-structured warm-up finishes with riders feeling:

Warm

Controlled

Confident

Ready to work

It should not leave riders fatigued, breathless, or relieved that it is over. If it does, intensity has crept too high or progression has been poorly managed.

Why this matters

Getting the warm-up right improves performance, reduces injury risk, and makes the rest of the session easier to deliver. For instructors, it sets the tone. For riders, it builds confidence and trust.
