Walk around the office
Collect documents from the printer and distribute them to your colleagues.

Tone your arms
Pick up weighty packages from reception and offer to deliver them to your colleagues’ desks.

Get some cardio
Wait till the last minute to go to the toilet, then run to the one three levels above yours.

Get off your ass
Put an alarm on your phone and place it at the far corner of your desk so you have to stand up to switch it off every half-hour.

Brisk walk
Don’t order takeout. Go to the restaurant and order your lunch personally.

Beat lunch coma
Hold an hour-long meeting in the conference room—without chairs.

Instil balance
Remove a wheel from your chair so you’re forced not to hunch all day long.
