Spot marching to complete 10k

I have night shift 9hrs desk job, where I'm sleeping during the day and when I wake it's dark and cold in the night and need to rush to office I somehow manage to hit the gym 5days a week, since I'm unable to go out anywhere I don't complete my 10k steps So if I just march on the spot infront of my desk,to completed the goal does it serve the purpose??
