Skipping the warm-up is one of the most common training mistakes, and one of the most easily avoided. People rush in, grab a kettlebell, and start swinging. Then they wonder why their back twinges or their shoulder feels off.
A proper warm-up takes 8-10 minutes. It prepares your joints, muscles, and nervous system for the demands you’re about to place on them. It reduces injury risk, improves performance, and makes the entire session feel better. There’s no good reason to skip it.
Why Warming Up Matters
When you’re at rest, your muscles are cool, stiff, and have limited blood flow. Your joints haven’t been moved through their full range. Your nervous system is in low gear.
A warm-up changes all of that:
- Increases muscle temperature, making them more pliable and less injury-prone
- Increases blood flow to working muscles, delivering more oxygen and nutrients
- Lubricates joints with synovial fluid, reducing friction and stiffness
- Activates the nervous system so your muscles fire faster and more powerfully
- Mentally transitions you from “sitting at a desk” mode to “training” mode
The 3-Phase Warm-Up
We structure every warm-up at Rush PT in three phases. It takes about 8-10 minutes and prepares you for anything the session throws at you.
Phase 1: Raise (2-3 minutes)
The goal is to elevate your heart rate and body temperature. Nothing fancy:
- Light jogging or brisk walking
- High knees
- Butt kicks
- Side shuffles
- Arm circles (forward and backward)
You should feel slightly warm and mildly out of breath by the end. Not exhausted. Just awake.
Phase 2: Mobilise (3-4 minutes)
Now we move every major joint through its full range of motion. This is where outdoor training has an advantage. We use the terrain:
- Hip circles: Standing, draw big circles with your knee. 5 each direction, each side.
- Leg swings: Forward/back and side/side, holding a post or tree for balance. 10 each direction.
- World’s greatest stretch: Lunge forward, elbow to inside of front foot, rotate and reach. 3 each side.
- Cat-cow: On all fours (or standing), flex and extend the spine. 8-10 reps.
- Thoracic rotations: On all fours, hand behind head, rotate to open the chest. 5 each side.
Phase 3: Activate (2-3 minutes)
The final phase fires up the specific muscles you’ll be using. This bridges the gap between “warmed up” and “ready to train”:
- Glute bridges: 10-15 reps to wake up the glutes (which switch off from sitting)
- Band pull-aparts: 10-15 reps to activate the upper back and rear deltoids
- Bodyweight squats: 8-10 reps at full depth, controlled
- Push-up hold: 20-second hold at the top position, core braced
- Light kettlebell deadlifts: 5-8 reps to prime the posterior chain
After this phase, you should feel alert, mobile, and genuinely ready to train. Not tired. Ready.
What NOT to Do Before Training
Static stretching (holding positions for 30+ seconds) before training has been shown to temporarily reduce power output and strength. Save your static stretches for after the session or your rest days.
Don’t skip the warm-up because you’re “running late.” Arriving 10 minutes late and warming up properly is better than arriving on time and starting cold. Your body doesn’t care about the clock.
Don’t use the warm-up as your workout. If you’re exhausted after warming up, you’ve gone too hard. Dial it back. The warm-up should leave you at about a 4 out of 10 effort level.
Cool Down Matters Too
After training, spend 5 minutes on a proper cool down. Light walking to bring your heart rate down gradually, followed by static stretches for the muscles you worked hardest. This helps reduce next-day soreness and begins the recovery process.
It’s not glamorous. Nobody posts their cool-down on social media. But it’s part of training properly, and the people who do it consistently feel better than those who don’t.
