Sometimes the things that some people do make you question their sanity (slip-n-slides are not good for the 25 and over crowd.)
Other times people inspire you to do things that you would rather not, things that are hard and can hurt.
My baby sister has got an iron will, when she sets her mind to something . . . well, it is best to just get out of her way. She decided a few months ago to take up walking and since she is one who doesn't do things halfway, she now walks 10 miles a day.
I wish I had a 1/4 of her willpower.
She doesn't know this, but she inspired me to start walking again. It is so hard starting exercising when you are overweight - ok, I am actually obese. Overweight would be easier. I think. There is a temptation to do too much in an effort to lose a bunch quickly. In the past, I would find some impractical workout program ("go from couch potato to running a 5 K in 4 weeks") and then give up after I injured myself. Following her lead, I started slow (we do have very different ideas on what "starting slow means" - and am working my way up but not to 10 miles a day. Maybe 5.
Right now I am up to 3 miles. Well, as of yesterday I did 3 miles and I don't know about today. It depends on how loud I hear my sister yelling at me to keep moving - she is like my own private Jillian. Except the real Jillian wouldn't actually kick my butt, my sister might.
