Warm-Up Routines

Warm-ups are one of the most consistently skipped parts of training — particularly when time is limited or motivation is low (common during a cut). They're also one of the highest-value things you can do per minute of gym time. A good warm-up improves session performance, reduces injury risk, and primes the nervous system for quality work.

Why Warm-Ups Matter More on a Cut

During a calorie deficit, your energy levels and recovery capacity are both reduced. You arrive at the gym in a slightly worse physiological state than you would at maintenance. A thorough warm-up compensates by raising body temperature, activating target muscles, and getting the nervous system switched on before you hit working weights.

Cold, under-activated muscles under significant load in a calorie-restricted state is a reliable recipe for minor injuries and poor performance.

The Components of an Effective Warm-Up

1. General cardiovascular activation (3–5 minutes) Rowing machine, assault bike, or incline walk. The goal is simply to raise core body temperature. You're warm enough when you can feel heat in your muscles and have slightly elevated breathing.

2. Targeted mobility work (3–5 minutes) Address the joints and ranges of motion you'll be using in the session. For a lower body day: hip rotations, leg swings, deep squat holds, ankle circles. For upper body: shoulder circles, arm swings, band pull-aparts, thoracic rotation.

This isn't a stretching session — it's controlled movement through ranges of motion to lubricate joints and prepare muscle groups.

3. Activation work (2–3 minutes) Specific exercises that "switch on" target muscles before loading them. Common examples:

• Glute bridges or clamshells before squats or deadlifts
• Face pulls or band pull-aparts before pressing movements
• Scapular retractions before rows and pull exercises

Activation work addresses the common pattern of dominant muscles compensating for under-activated ones during compound lifts.

4. Progressive warm-up sets Before your first working set at your working weight, perform 2–3 build-up sets at lower intensities:

• Set 1: Bar only or 40% of working weight × 8 reps
• Set 2: 60% × 5 reps
• Set 3: 80% × 3 reps
• Working weight: Begin your planned sets

Time-Efficient Warm-Up (Under 10 Minutes)

For time-pressed sessions:

1. 3 minutes incline walk or rowing machine
2. 5 mobility exercises specific to the session (30 seconds each)
3. 2 activation exercises (15 reps each)
4. Progressive warm-up sets for the first compound movement

This covers all the essential components without extending your session significantly.

What to Skip

Traditional static stretching (holding a stretch for 30–60 seconds) before training has been shown to temporarily reduce force production. Save static stretching for after training or separate mobility sessions. Pre-training mobility work should be dynamic — controlled movement through ranges, not prolonged holds.

Key Takeaways

• Warm-ups are particularly important during a cut when energy and recovery are reduced
• A complete warm-up has four components: cardiovascular activation, mobility, muscle activation, and progressive warm-up sets
• 8–10 minutes is sufficient for an effective warm-up — it doesn't need to be lengthy
• Avoid static stretching before training; use dynamic mobility work instead
• Progressive warm-up sets prime the nervous system and movement patterns without accumulating fatigue
• Skipping warm-ups during a cut significantly increases injury risk at a time when recovery is already compromised
