1,000 days of burpees

posted by Joshua on September 16, 2014 in Exercises, Fitness, Habits, SIDCHAs

If I did my math right, today is my one-thousandth day of burpees, starting at one set of ten per day, now up to two sets of twenty-five per day.

That’s somewhere over 40,000 burpees. I’ve done them in North Korea, China, and across the U.S. Following the principle that if you miss one day you can miss two, if you miss two it’s all over, I haven’t missed one rep since starting.

They are about discipline and dedication as much as fitness. More important for some people, since I’ve done most of them on my own and no one would know if I skipped them, they are about integrity.

Some advantages to them I don’t mind repeating.

  1. They put me in the best shape of my life
    1. At over 40 years old
    2. After a lifetime of athleticism including playing Ultimate Frisbee at the Nationals and Worlds level and running five marathons
  2. Zero cost
  3. Zero equipment
  4. Negligible risk of injury
  5. Can learn to do them in seconds
  6. Documented by fitness experts as single best exercise
  7. Under five minutes per day
  8. Can do them anywhere, any time, in any weather
  9. Don’t interfere with any other workouts
  10. Can work at any level — just do as many or as few as you want
  11. Many variations can work specific parts of body
  12. They make you feel great
  13. Teach discipline, dedication, drive, and focus

Good luck with your burpees or other SIDCHAs!

In motivation, influence, and persuasion, sales and leadership overlap a lot. Sales is also the most common route to CEO, I’ve heard, so if you want to lead, you benefit from learning sales. Below is a video interviewing a guy who is incredible at sales. He sold an apple for five dollars, with the buyer[…] Keep reading →

Grunt work and sales leads to leadership roles

posted by Joshua on September 14, 2014 in Leadership
Leave a comment

Most of the work of leadership is grunt work—doing what it takes to support the people you’re leading. Then some sales work to make sure people don’t see you as just a grunt worker. You have to take responsibility for how people see you because no one else will. I recently took on a leadership[…] Keep reading →
