Having lots of comfy chairs at a breakfast bar encourages camping out in the kitchen. Likewise, a living room full of recliners will lead to excessive lounging. A 2005 Mayo Clinic study that followed both lean and mildly obese people found that obese people sat at least 150 minutes more each day. Living rooms should be comfortable, but if you're going to spend a lot of time in there watching TV, consider keeping manual exercise equipment (like hand weights and resistance bands) accessible in a basket, storage ottoman, or decorative chest instead of stashing them in a closet. If you have a treadmill, consider giving it a home in the living room and squeeze in some exercise in during your favorite shows.
