“It’s common wisdom that missing a day or two of exercise makes it harder to get back to it the next day, but The New York Times points out that it’s not as cut and dried as simple motivation. A number of other factors show how important consistency is when sticking to a workout.”Thorin Klosowski

So it’s important to have an activity that keeps us engaged and excited about coming back. Just another reason to “keep training.” When you practice Aikido, training in a spirit of support and cooperation with others, it’s easy to keep showing up (hard not to, actually). Having regular classes to look forward to is so much more fun than “trying to get around to exercising more.”
