The basic idea is to take things that you do every day already, and add a small task to them so you don't feel like you're doing much more work.
Cleaning the kitchen while my coffee brews is a good one. Every morning I would wake up come downstairs, get the coffee brewing and watch TV for about 5 minutes until it was done. Drinking coffee for me is one thing that happens every morning without fail. So instead of sitting down on the couch I decided to use this time to clean the kitchen. I was in there anyway right? So now I load/unload the dishwasher, clean counters, etc for a few minutes until my coffee is ready and then sit on the couch and watch TV until I am ready to start my day.
Second thing is I always drink a cup of water before my coffee so I don't get too dehydrated, so now I always take my vitamin D and fish oil (It doesn't cause heartburn on an empty stomach like C).
Before I start cooking I clean the kitchen. This with the coffee brewing tag make it so I no longer have to set aside extra time for cleaning the kitchen, I just automatically take care of it.
Here are a bunch of other ones:
Always floss when I brush.
Start laundry/washing machine/dryer every time I leave/enter the house.
Every time I walk into or leave a room, do 1 thing, for instance pick up a toy, make the bed, throw trash away, etc...
Exercise right before taking a shower, I usually do some stretches, push ups, and sit ups.
Whenever you get home, check the mail and/or take the garbage cans back in.
Whenever you leave, take the garbage cans out to the street if they need it.
The first thing I do when getting out of the shower is make the bed.
Whenever your on hold, clean your desk.
I'm sure there are a thousand others, but you get the idea.
