How to Skate Off One Pound For each pound of weight you want to lose, you will need to burn off approximately 3500 calories. According to a calorie chart published by Rollerblade, a 150 pound person skating 11 miles per hour burns about 10 calories per minute. This means a 150 pound person skating 11 miles per hour would have to skate 6 hours to lose 1 pound (3500 calories / 10 calories = 350 minutes. 350 minutes / 60 minutes per hour = 6 hours of skating) If you skate enough to burn off an extra 800 calories per day, you will lose 20 pounds in approximately 3 months. If you give yourself 6 months to lose 20 pounds, you only need to burn off an extra 400 calories per day. The amount of skating required to burn off 800 and 400 calories will vary widely from person to person, because it depends on your personal body weight and skating speed.
