Choose your swaps: Pick a few routine moments to add movement - e.g., one floor by stairs, stand for one call.
Make them the default: Put sticky notes or phone nudges where the action happens.
Keep it flexible: On heavy days, do just one swap and count it as done.
Stand for your next call instead of sitting.
Prioritise safety: good footwear, clear floors, and steady support for balance moves. Stop any movement that causes pain and replace it with a comfortable option.
