Can you tell me how many calories i just burned off?

Question

I did a 40 min brisk walk on the treadmill at 3 different elevations. then I swam laps for 30 min. Then did weights for my arms for 20 min.

Answer 1

Hmmm i would say oh 300-600 calories. I could get a better estimate if i knew your age, height, and weight but you don't have to post that if your not comfortable.

Answer 2

I'd say about a good 3, 4 hundred!
