A fourth way to make activity easier is to lighten the load by sitting to do the task or by reducing lift and carry. Sitting uses less energy by taking the load off your body just in the same way that using trolleys can take the load off when you are moving.
Examples of this sitting to do the ironing, sitting to pot plants, leaning on the trolley in the supermarket, using a wheel barrow in the garden, a tray mobile in your living area, or a laundry trolley in the yard.
If you are struggling in getting about then try a wheelie walker that includes a seat and basket and this will assist you in staying mobile and connected with your community.
