I work grueling hours that barely let me eat and sleep, let alone, consider exercising or engaging in a sport.

There may be times in your life when activity has to take a back seat to professional and personal obligations. But if you allow that attitude to guide your life, you'll always have an excuse. So make the commitment to carve out some "activity time."

Follow this starter kit: Introduce activity like walking in small spurts during your weekdays. Use a short workday break or mid-day lunch period to squeeze in some power walking or movement. Create a weekend window on Saturday and Sunday for fun activities like biking, beach running, in-line skating or take a fun class at a local gym and make 'weekend friends'. They can be your reason to keep up your weekend activities, a sort of mini pressure reason to show up — which you ultimately enjoy. The accumulation of daily activity, plus the weekend boost, will have a huge impact over time.

I can't find something I like enough to keep me sticking with it long term.

There are probably more than 100 sports, exercise disciplines, dance options to choose from so I assume you've tried them all, right? Well if not, now's the time to begin the adventure. I have had so much fun over the years trying new sports and finding the ones that fit with my available time and my personality. I've discovered that I love low impact/dance and aerobics, boxing, tennis and running. So I incorporate all these loves into a weekly routine. It defies boredom, keeps me challenged, allows me harder and easier days of activity and each requires a different time commitment.
