Does this cl as a workout?

basically i work at argos and occasionally i get them job of picking the items for the lovely customers :D for the americans on here of people that dont have an argos basically wat it is u order the item at a til using a catagloge number then u take a seat and 4 mins later ure item will be there for u to collect. now bear in mind im not sure if ure aware of this but most argos stores on a weekday have only 2 people picking 1 upstairs and one downstairs. this means if u work a fall day u will have to go get about 500 items which some can be as heavy as 30kg so does this cl as a workout u are constantly power walking then u have heavy amounts to lift and get to the customer in 4 minutes basically the picker actually has around 60 seconds to get the items to the collection desk
