Did you know that jumping rope for 15 minutes burns 300 calories?
Lol… yeah right. Calorie counters are garbage—let me explain why.
A recent @Stanford analysis of fitness wearables found that they overestimate calorie burn by an average of 27%, with the least accurate device being off by a whopping 93%. In short, they all suck at tracking calories. However, they are pretty solid at tracking heart rate, with an error rate of less than 5%.
For context:
🏃♂️ Elite marathon runners may burn around 1000 calories per hour
🚴♂️ Olympic cyclists at peak intensity can hit 1500 calories per hour
But you and I? We’re not torching 1200 calories in an hour, no matter what some Gym Bronies might think…
