Always Perform at Least One Warm-Up Set

10-Second Takeaway

• Every exercise gets at least one warm-up set. No exceptions.
• Warm-up sets are specific to the exact movement you’re about to perform.
• Keep warm-ups low reps per set, gradually build up in weight, and move through them with minimal rest.
• Adjust the number of warm-up sets day-to-day and movement-to-movement based on readiness.

Core Principle / Mechanism

Warm-up sets are not general preparation. They are movement-specific rehearsal.

If the working set is a barbell incline press, the warm-up must also be a barbell incline press. If you’re about to perform standing cable curls with a bar, your warm-up is standing cable curls with a bar. General mobility work or similar exercises do not replace this step.

The nervous system prepares best when the preparation mirrors the task.

Warm-up sets done right allow you to optimally:

• Dial in load
• Establish clean technique
• Calibrate effort (RIR) and weight
• Groove the exact pattern you’re about to load

They also sharpen mental intent, giving you a moment to feel the movement, assess coordination, and lock into execution before the working sets where results are actually driven.

Done well, this improves performance and reduces sloppy reps that quietly limit progress (or increase injury risk).

Decision Rules / Practical Application

• Baseline rule:

Every exercise starts with at least one warm-up set.

• Match the movement exactly:
• Same movement
• Same setup
• Same equipment
• Reps stay low (1–5):

Warm-up sets are not mini working sets.

You don’t need to match the prescribed 8–12 rep range. That just creates fatigue.

Instead:

1. Perform 1–5 reps
2. Increase weight
3. Move on with little to no extra rest
• Bridge the gap to your working weight:

Warm-ups should progressively close the distance between empty/light load and your working sets.

Example progression:

1. Light → Moderate → Near working weight → Working sets
• Adjust based on context:

Early in session:

1. More warm-up sets are typically needed
2. You’re transitioning from rest → output

Later in session:

3. Fewer warm-ups needed
4. You’re already primed and coordinated

Low readiness (poor sleep, stiff, fatigued):

5. Add more gradual jumps
6. Potentially more warm-up sets

High readiness:

7. Fewer sets, bigger jumps
• Litmus test:

If your first working set feels smoother, more controlled, and more “locked in” than it would have otherwise then your warm-up did its job.

Common Mistakes

• Treating warm-ups as optional
• Using unrelated movements instead of the actual lift
• Matching working set rep ranges (this is almost always too fatiguing)
• Taking excessive rest between warm-ups
• Adding unnecessary volume “just in case”
• Rushing through without intent

Exceptions & Edge Cases

Very light/isolation movements:

May require fewer ramp sets, but still benefit from:

• Pattern rehearsal
• Load calibration

Rehabilitation / pain-sensitive contexts:

• Slower tempos
• More gradual ramping
• Additional sets as needed

Highly technical lifts (or newer movements):

• May benefit from slightly more exposure to groove pattern
