This is the FIRST thing that has worked for me...
We all know that we can promise ourselves to exercise but its also easy to let ourselves down and not do it. My friend and I were sharing this same struggle.
We decided that we would exercise 20 minutes 5X/week. On our own... whatever exercise we wanted. We kept track on our own calendar. (we actually make fun exercise calendars on Publisher)
If we both reach our goal for 4 weeks, we get a "Girls Day Out". If one of us doesn't reach the goal, we have to start the 4 weeks over.
I know that if I mess up, all of her work is "wasted" and she misses out on the day out, not just me.
It's worked perfectly. We've been consistent since the middle of August!!!!! We're really noticing the difference! And even though our busy schedules has made us fall behind in using up our Day Out together, we still keep going.
No doubt you have a friend that wants to get in shape as well. Team up!
