One of my daily goals is to hit 100 SparkPoints. When I do that, I've not only read articles, I've interacted with other members by reading and commenting on their blogs and writing my own blog. 100 points gets me here and gets me active each and every day.
When I started, I made the commitment to workout daily and write a blog about it. On days when I don't feel like doing it, I think about the blog I need to write and I certainly do NOT want to write that I was lazy and did not work out.
Maintain your goals on your SparkPage (that's what all the goal-setting gurus write about) and make the goals public on your page. Write about it on your blog every day.
Weight loss = calorie maintenance, cardio, and strength. Calorie maintenance is every day, cardio is at least five days per week, and strength is 3 to 4 days per week. I believe you need all three for a successful weight loss and fitness program.
Above all, be consistent. Doing something toward you goal every day will pay big rewards over the next few months. You can do this!
