How to Burn More Calories Running 3 Miles
Want to maximize calorie burn? Try these strategies:
1. Increase Your Running Speed
-
Sprinting intervals (e.g., 30 sec fast, 1 min slow) can boost calorie burn by 25%.
-
Aim for a 7-8 min/mile pace if possible.
2. Run on Inclines or Hills
-
Running uphill burns 30-50% more calories than flat terrain.
-
Treadmill users: Set incline to 2-5% for extra intensity.
3. Add Strength Training
-
Muscle mass increases resting metabolic rate (RMR).
-
Combine running with bodyweight exercises (squats, lunges).
4. Try HIIT Running Workouts
-
Example: 1 min sprint, 2 min jog (repeat for 20-30 min).
-
HIIT burns more calories in less time compared to steady-state running.
5. Stay Consistent
-
Running 3-5 times per week leads run 3 to better fat loss results.
-
Track progress with a fitness watch (e.g., Garmin, Apple Watch).
