Are you ready for the Plank Challenge? Here are the details!


The Plank Challenge is actually really simple. It will take place for a total of 4 weeks (October 22 – November 16) and will only require 10 minutes or less of your time on Monday, Wednesday, and Friday of each week. Monday and Friday will be time trial days when you hold a plank, time yourself, and record it. On Wednesdays, I’ll post a plank/core workout (10 minutes or less) on CNC to help you build up your strength and stamina. Basically, the weeks will look like this:

  • Monday: Time trial
  • Wednesday: Plank/core workout
  • Friday: Time trial – try to beat Monday’s plank time!

I did my first plank of the Challenge last night and made it to 3:00 minutes, so my goal for the Challenge is to double my time. I think doubling your plank time in 4 weeks is a great goal, so feel free to set the same one for yourself! If you haven’t done your first plank yet, do it sometime today, so you can start with the plank/core workout tomorrow.


To help keep me on track, I set a bunch of time goals for myself and added them to my calendar. I know holding a plank is all about core strength, but a lot of it is mental too, so if I have a time in mind to strive for, I’m more likely to tough it out and achieve it!

I hope you decide to join my Plank Challenge! I’ll be blogging about it on Mondays, Wednesdays, and Fridays for the next 4 weeks, and I’d love to have some buddies to do it with me so we can all keep each other motivated! Let me know if you’re in for the challenge!


Last night’s dinner was quick and nutritious. Mal and Dave got take-out for dinner, but I wasn’t in the mood for it after eating out quite a few times this weekend, so I whipped up a simple meal of canned tuna mixed with sautéed spinach, red peppers, avocado, fresh basil, salt, and pepper.


A little while later, I made myself a sweet treat: sweet potato slices with Nikki’s vanilla cake batter coconut butter and cinnamon. OMG, delicious!

  1. I tried to do a trial this morning after some arm strength training and only lasted 30 seconds before I started shaking! My arms totally gave out… so I just tried it again and lasted 2 minutes. So I guess my goal is 4? I will be so proud if I can get to 4!!

  2. Hi! I did my time trial this am…3:00. Told my husband when he got home from work, so he tried it..5:01. It’s ON!!!!! I know our goal is to try and double our times, but my goal is to beat him;).

  3. Looking forward to joining you on the 4-week plank challenge. This is just the motivation I needed to strengthen my core for the Philly half I am doing on November 18th.

  4. My trial time is 2:31..and that’s after a boxing class and twenty pug kisses so I hope I can kick it up and meet my goal of 5:01 in four weeks! Thanks for a fun challenge!

  5. I am currently ruuning a plank challenge with a group but I want in. I would love to challenge myself further and learn from you.

  6. I’m in! Thank you for specifying that you did 3 minutes, that inspired me to do 3 minutes too! I can’t imagine doubling that in 4 weeks though. It was HARD. Thanks for a great challenge idea. I look forward to sharing progress and trying your workouts.

  7. My boyfriend and I are totally in for the Plank Challenge! My first time was 59 seconds and his was 1:19. I definitely feel like there lots of room for improvement. I can’t wait!

    P.S. We’re going to our first Crossfit class next Tuesday! WOOT!

  8. Did my first plank tonight. That stuff is hard!!! Lol I lasted 80 seconds. Silly question….how often do you do them and how many times to build up to your goal?

  9. I will be joining my girlfriend Elizabeth in the challenge. I started with 3:03. My goal is to double my time after four weeks and end at 6 minutes.

  10. I’m in!

    My first plank time was 2:01, but my glutes and quads are burning from a 400m walking lunge challenge at my CrossFit box, so hopefully I can more than double that to get to 5 min!

  11. Initial time: 2:08.
    I’ve been so excited about this since you first wrote about it that I have been dropping and planking several times a day!

    I also absolutely love your blog and my breakfasts have gone from bread-y type foods to scrambles and pancakes that have made me feel so much better.

    Thank you for the inspiration and for the laughs (I love Murphy!)


  12. I did my plank think morning, and I got 1:13. Better than I thought! My goal is going to be a cool even 3 minutes. Thanks for doing this Tina!

  13. I’ve been trying to a plank a day since I started CrossFit 1 month ago, but my core still isn’t really where I want to be. I will continue doing 3x 1 minute planks (which are hard for me) each day, and will probably do the core workouts you post. 6:00 is a great goal! Always seeing coconut butter on your and other blogs makes me want to go out and grab some.

  14. Got this done last night and my time was only 1:57 🙁 Not happy with that, but the weird thing is, it was more my legs struggling than my abs (probably from a deadlift series the night before). Planks really are full body!

    Lots of room for improvement here 🙂

  15. I’m totally doing this with you! I timed myself yesterday and I’m at 4:24. Can’t wait to see your post on the Wednesday Challenge/Work out!

  17. I’m in for the plank challenge too! 45 seconds is my record so I can’t wait to double it! i’m so impressed with everyone else’s numbers!

  18. Plank Challenge Day One: 2 minutes, 26 seconds. Not bad for an almost 50 year old – yoga and Nike Training Club is working!

  19. I just saw a mention of your plank challenge on the pile on the miles challenge. A few days late, but starting today. day 1- 1 minute. I’d like to double that, or more!

  20. another later joiner, but better later than never. 😉 i did 1:16 min today with the goal to double that number in three weeks.

    thanks for setting up the challenge!

  22. Well, I’m late and missed the first week, but I did my first time trial today- 1:21. I don’t think my form was good at the end though because I’m feeling it in my lower back now.
