Aha, it was quite a last minute activity, so I suppose, one day you suddenly started seeing a lot of running posts on moments.
I think a way to think about the 21 days is like proving that you can stick to something knowing that it will at some point pay off. Perhaps it takes longer than 21 days, and perhaps it is something mental and not physical. Proving that you can stick at it for a reasonable time frame gives you the confidence to attack other things in life the same way.
In the end, we all have to assess whether the juice is worth the squeeze. Gaining some cardiovascular fitness and health and fitting in our 10k steps a day certainly can't do much harm right?
Maybe you would be able to join us for the next challenge, whenever and whatever that may be!
You are so right, it is also an excellent cardio exercise and mentally it is super energizing, I usually do cardio on an orbitreck because I have it at home and when I get home from work at night I have it available, but I have been sick for a while and I had to stay away for a while too, now I feel better, I should definitely come back fast! really thanks for the motivation, I needed to read this today.
