How to Warm Up Properly: The Science-Based Approach
Why Warm Up?
You know you should warm up, but maybe you skip it when pressed for time. Here's why that's a mistake:
Performance benefits:
Injury prevention:
A proper warm-up makes your workout better AND safer.
The Old Way vs. The New Way
Old approach (1980s):

Current evidence-based approach:
The 4-Phase Warm-Up
Phase 1: General Warm-Up (3-5 minutes)
Goal: Raise core body temperature and heart rate.
Options:
Intensity: Light to moderate. You should be slightly warm, maybe starting to sweat.
Phase 2: Dynamic Stretching (3-5 minutes)
Goal: Move joints through full range of motion with controlled movements.
Lower body:
Leg swings (front to back):
Leg swings (side to side):
Walking lunges:
Walking quad stretch:
High knees:
Butt kicks:
Hip circles:
Upper body:
Arm circles:
Arm swings:
Shoulder circles:
Thoracic rotation:
Cat-cow:
Phase 3: Movement Preparation (2-3 minutes)
Goal: Activate key muscles, especially ones that tend to be "sleepy."
Glute activation:
Glute bridges:
Clamshells:
Monster walks:
Core activation:
Dead bugs:
Bird-dogs:
Plank:
Shoulder activation:
Band pull-aparts:
Band external rotations:
Phase 4: Specific Warm-Up
Goal: Prepare for the exact activity you're about to do.
For strength training:
- Bar only × 10
- 95 lbs × 8
- 135 lbs × 5
- 165 lbs × 3
- 185 lbs × 1
- Then working sets at 200 lbs
For running:
For sports:
Sample Warm-Ups
For Strength Training (10-12 minutes)
1. General: 3 min rowing or jogging
2. Dynamic stretching:
- Leg swings: 15 each direction
- Walking lunges: 10 each leg
- Hip circles: 10 each way
- Arm circles: 10 each direction
3. Activation:
- Glute bridges: 15
- Dead bugs: 10 each side
- Band pull-aparts: 20
4. Specific: Warm-up sets for first exercise
For Running (8-10 minutes)
1. General: 3-5 min brisk walking or very light jog
2. Dynamic stretching:
- Leg swings: 15 each direction each leg
- Walking lunges: 10 each leg
- High knees: 30 seconds
- Butt kicks: 30 seconds
- Hip circles: 10 each direction
3. Activation:
- Glute bridges: 10
- Single-leg balance: 30 sec each
4. Specific: 3-4 strides (short accelerations)
Quick Warm-Up When Short on Time (5 minutes)
1. Jumping jacks: 30 seconds
2. Bodyweight squats: 15
3. Walking lunges with rotation: 8 each leg
4. Arm circles: 10 each direction
5. Leg swings: 10 each direction each leg
6. 10-second run in place
7. Go to activity-specific warm-up
Common Mistakes
Skipping It
"I'll warm up during the workout" doesn't work. Cold muscles don't perform or protect you.
Too Much Static Stretching
Save static stretching for after your workout. Before exercise, use dynamic movement.
Too Long or Too Intense
The warm-up should prepare you, not tire you. If you're fatigued before your workout, you've overdone it.
Same Warm-Up for Everything
Customize for your activity. A squat session warm-up differs from a running warm-up.
Ignoring Problem Areas
If you know your hips are always tight or your glutes don't fire well, address those specifically.
What About Static Stretching?
Static stretching (holding stretches 30+ seconds) has its place—just not before intense activity.
When to static stretch:
Exception: If you have a severe mobility limitation that prevents proper movement, brief static stretching before activity may be warranted. But this is the exception, not the rule.
The Bottom Line
A proper warm-up takes 10-15 minutes and dramatically improves performance while reducing injury risk. The formula:
1. Get warm (general cardio)
2. Move through range (dynamic stretching)
3. Activate (wake up key muscles)
4. Rehearse (specific preparation)
Stop skipping your warm-up. Your body—and your performance—will thank you.
