Exercise at work

I work in retail (I'm a manager) and I spend my 8 hour shifts walking around the store and climbing ladders to change mannequins. I count this as exercise because without my job I'd be a pretty sedentary college student. I'd like to record how many minutes I exercise per day on Glow, but I feel like 8x60 is a ridiculous amount of minutes to say that I was "exercising". What would y'all do in this instance?
