Approx how many calories?

Options
I am disabled so I can only do upper body exercises when I do not have OT. I walk with my OT. Yesterday I did the Denise Austin Upper Body Workout Level 1 (10 Minutes) but the workout is not in the database so I have no clue how many calories I burned. Also, if anyone knows how many calories are burned when taking 165 steps, I'd appreciate the info. Thanks!
