Your Class Is Only as Good as Your Warmup

The main workout gets the most attention. Programming directors obsess over intervals, rep schemes, and energy system sequencing. Coaches rehearse cues. Operators track class ratings and completion rates.

The warmup? Usually whatever the coach feels like doing that morning.

That is a weak start to a class you have spent real time programming.

The Warmup Is Not Optional Setup

Members make a judgment call in the first few minutes of every class. Is the coach prepared? Is this class worth their time? Will they come back?

The warmup gives them an early answer.

A generic warmup - 20 jumping jacks, a couple of arm circles, maybe a lap of the floor - can feel disconnected from the session members came to do. Those movements may fit, but the coach should know why they are there. The warmup is part of the class, not the bit everyone waits through.

What Most Warmups Actually Do (and Don’t Do)

A warmup prepares members for the work ahead. A 2010 systematic review and meta-analysis found performance benefits across many of the outcomes studied, although the evidence varied by activity and protocol.

The coaching opportunity goes beyond getting warm. A member can complete a light movement circuit and still have no idea how the first working block is meant to run. Use the time to prepare the movement and explain the session.

Use the warmup to:

• Preview the patterns in the main session so members know what’s coming
• Check how members move before the working sets
• Give people time to settle in and ask a question

Skip that preparation, and your first working set becomes the place where members learn the movement, choose the load and try to keep up at the same time.

Movement-Specific Prep Over Generic “Getting Warm”

The most useful warmup principle is also the simplest: the warmup should look like a lower-stakes version of what’s coming next.

If the main set is a lower-body strength block, the warmup needs to include the relevant lower-body patterns. If you’re programming hip hinges, the warmup should include hip hinge patterns - unloaded hinges, good mornings or light Romanian deadlifts (RDLs). If the session involves rotational power, the warmup should prime rotation.

This isn’t complicated. It just requires the coach to think about it in advance.

What that produces: members arrive at the first main-set exercise already familiar with the movement pattern. The first rep doesn’t have to be both a warmup and a working set. That gives the coach a chance to check understanding and choose an appropriate starting load. Progression still depends on the member and the exercise.

From the member’s perspective, the class feels intentional. Connected. Designed by someone who thought it through.

Coaching the Warmup

This is where things break down even when the exercise selection is right.

A lot of coaches treat the warmup as transition time. Members are still arriving, music gets turned up, the coach is sorting equipment or chatting at the desk. The warmup just… starts. Movements get announced but not explained. Reps get counted but not coached.

A coach says “goblet squat” and the room starts moving. Some members know the pattern. Others copy the person next to them. Length of membership will not tell you which is which; a demonstration and a few practice reps will.

The warmup is a useful place for demo reps: keep the pace and load manageable, make sure members can see, then give them time to try what you showed them.

Build a simple default into your warmup standard: show the movement, give one or two useful cues, let members try it, then check understanding. A familiar movement may take one demo rep. A more technical one may need several. The standard is a clear demonstration followed by coached practice, not a fixed limit on explanation.

That’s it. But it changes the class.

The New Member Window

For a first-time member, the warmup is part of the orientation: where to stand, what to do and how to ask for help.

For a new member in their first class, the room, equipment, coach’s voice and format may all be unfamiliar. They need anchors. They need signals that they’re in the right place and that someone is paying attention.

A coach who walks through the warmup with clear demos and brief orientation cues (“this is the same format every time - warmup, main set, finisher”) is giving the new member a roadmap. A coach who says “alright everyone, grab a mat” and starts counting is leaving that member to figure it out on their own.

The demonstration gives that new member something to follow before the pace picks up.

What a Good Warmup Structure Looks Like

Here is a 6-9 minute starting structure you can adapt to the format:

1. General movement (2-3 minutes) Get the cardiovascular system moving. Something that applies to most body parts - bike, row, or ski erg at low effort, or a light movement circuit. Purpose: raise body temperature, get members oriented and breathing.

2. Pattern-specific prep (3-4 minutes) Preview the movement patterns from the main block at light load or bodyweight. This is where the coaching happens. Demonstrate, give a cue, watch the practice reps. Add explanation if people need it before moving on.

3. Activation and priming (1-2 minutes) Choose one or two relevant preparation movements, then rehearse the first exercise with a suitable load. Use the response to decide whether members need more preparation or a different option. These choices should come from the session requirements, not a universal activation routine.

Total: 6-9 minutes in this example. Adjust the time to the session and members. A heavy strength block may also need progressively loaded practice sets before the working sets; do not rush them to meet a fixed clock.

How to Standardize Across Your Coaches

If your programming is centralized, the warmup should be too. Coaches shouldn’t be improvising it session by session. Write it into the program the same way you write in the main set.

When you review a coach’s class - live or on video - include the warmup in the review. Ask: was it connected to the main session? Were movements demoed? Were cues used? Did new members have what they needed?

For coaches still running generic warmups, the conversation isn’t “your warmup is bad.” It’s: “what does a new member need to know in the first five minutes to succeed in the next 50, and does your warmup give them that?”

That reframe tends to stick.

The Class Doesn’t Start When the Music Kicks Up

The class starts when members walk in the door. The first few minutes set the tone for what follows.

A warmup that’s designed, coached, and consistent tells members - new and returning - that whoever is leading this class has thought about them. That’s not a small thing. It’s the foundation of everything that happens next.
