I'm going to have to make a dramatic change in my exercise routine...

Hello ladies, I've drifted away from our nice little community here, and boy have I regretted that! I've discerned that this happened around the same time that my Stroller Strides group changed dramatically. I've been doing that Mom and Baby program for over 3 years, and its been mostly great, but the mood of the group has changed a lot over the past few months and the differences between the activities of the group this year are very VERY different from this time last year. Some of the changes have been small, and even good, but some are causing me to believe that it is time for me to move on. I'm not sure how to tell the woman who owns the franchise with out it being a big issue. But I have been praying about it a good deal and I really feel like God has been calling me towards a change, almost a feeling of the group holding me back from doing what I really should be doing.
Also I'm worried about finding motivation to get out of the house and also to keep exercising once I've stopped going. Any Advice ladies? Also has any one tried the Rosary Workout...I'm considering that as an option...
Thank you!
Jamie
