Put one foot in front of the other... One of the toughest things to do is start a new program.  When I first came back to running after 20+ years off, I had a lot of false starts, mostly because I let my competitiveness get the best of me.  I didn't want baby steps, I wanted marathons!  And I ended up with pain and frustration.  I took a step back and looked for some help from people who had been there and done that.  And what I found is there are TONS of resources out there for easing your way into fitness, and they most are FREE! So, I ended up using Hal Higdon's 30/30 plan, which I have written about before and the link to which is on my right hand side bar.  This program eases you into running over a 30 day period.  And it only takes...you guessed it, 30 minutes a day!  By the time I got done with the 30 days, I was completely ready to drop the walking portions and get on with my running.  But, I forced myself to take it slow and easy until I graduated.  All these years later, Hal Higdon is still my go to guy for starting a running habit. My wife had great success starting out with Leslie Sansone's "Walk Away The Pounds" DVD's.  They also start slow and you can build up to an amazing level a little at a time.  And she has introduced me to Wii
