Copied from other board section:
The Streak idea is presented by Chris Downie in the Case Studies section. Some of us have jumped on this idea and are doing Exercise Streaks; Chris's Streak is an exercise Streak also. A Streak is something to be designed personally by you. Chris's streak is a 1000-day streak.
If a Streak of anything other than exercise motivates you, get one started under the Challenge topic to let us know about what is going on with you.
If you are doing a continuous Exercise Streak of days and need muscle rest days, walk, do upper body work on a lower body rest day, do flex yoga, etc.
If you have an exercise plan designed to ensure a balanced work out (weights, cardio, flexibility), do not be stuck on the exercise plan. Instead be stuck on the Streak itself. Get that Streak done even if what you do is not what you planned to do. In situations that interrupt your plan (too tired for weights, kid needs to be watched in the pool or taken to the playground, sitting on an airplane, suffering with a bad cold,
etc.), do something that will count for The Streak and will work with the situation. (Chris Downie has gone so far as to jump rope in an airport.) Focusing on The Streak rather than the exercise plan itself encourages you to be creative. The more you create, the better you get at Streaking and the more fun you have exercising. Keep in mind that although spontaneously doing your Streak every day is more fun than following a plan, a well-made exercise plan can ensure that you will become highly fit (as long as you eat clean) and create a great body. Remember: There is something about the creative aspect of devotion to The Streak that gets you looking forward to exercise. It is a really cool experience.
