Sometimes it can be as easy as changing up the music in your ipod.. I know it sounds dumb, but I have this "running music" I always listen to when I run, but after about a month or so I have to change up a lot of the songs, get something new a fresh in there...
Also with the spring/summer weather being here now, get outside... Go to the park, I bought a bike this year (it's a cute cruiser bike with a basket and a bell), I don't drive my car anywhere less than what a 5 minute drive would be..
I do like the idea of a pole dancing class too... Such a great work out from what i've heard and so much fun!
Keep up the good work! It's so worth it!
