Hilary White of PopSugar just posted a great blog post about why she doesn't work out, and what she does instead. Here are here four tips for a non-gym rat life, with some of my ideas attached :)
1. I stay constantly active and on my feet.
Be constantly on the move, even at work. Get up and down several times an hour wherever you are. On the weekends, make sure to allow yourself some downtime with Netflix or a good book, but I don't waste any sunny days sitting on the couch.
2. I walk everywhere I can.
If you're lucky enough to live somewhere that you can walk comfortably to other places, do it! Even if it takes a half an hour, walk to the grocery store then bus back! Ditch the subway and walk a few more blocks.
3. I eat healthy.
Exercise is only half the battle. You need to eat right to make any difference in your body. Stick to things that are natural, clean, and not overly prepared, like vegetables, fruits, fish, and meat. It makes the workday go by faster when you get to snack on something every couple of hours, anyway!
4. I make fitness fun.
Stop pushing yourself to go to classes and join a gym, but instead save your energy for activities that you can get really excited about.
