It must be gratifying to fly in the face of people who said it could not be done!
Having said that, I believe little rewards for reaching goals also motivate and prevent feelings of guilt for having 'wasted' time or money on things that lie unused. I walked barefoot until I was sure I would walk every day - then I bought myself good walking shoes (quite an expensive buy for my lifestyle). The shoes increased my speed and commitment.
Next on the list is consistent body weight strength training and rewarding myself after I do a consistent 30 minute workout! Exercise bands and dumbbells on next on my to-buy list.
In the end, whatever works, is fine! You know best what will light the fire under YOUR butt and get it moving!
