Answer:
you need to base it off your weight
Step-by-step explanation:
For example: If you weigh around 200 lbs, a 90 minute hike over small hills, with a 10 lb backpack will burn over 700 calories. Increase the incline of those hills and that calorie burn will be closer to 900 calories. To lose a pound of weight you need to burn 3,500 calories more than you eat.
