Week 3 : Begin with a brisk 5 minute walk then two repetitions of 90 seconds of running, 90 seconds of walking, 3 minutes of running, 3 minutes of walking.

Grr Argh!

This week's plan seemed like quite a jump from the plans of Weeks 1 and 2. Gone are the days of doing more walking than running. We're getting serious now.

What really stood out to me this week was the insidious little voice that suddenly appeared in my head and started to tell me how easy it would be to quit. "This is hard". "You're finding it tough". "You can't do this". "You could just quit".

From experience, I know how easy it can be to dwell on those poisonous little darts of negativity that creep into your mind, and before you know it, you've talked yourself out of either starting a project or carrying on with one. I can definitely be my own worst enemy and I didn't want that to happen this time.

So I shared the murmurings with my husband and acknowledged I was thinking about giving up. Giving them a voice out loud took them out of my head and I found I could look at them more objectively. This, along with the fact I can be a stubborn old mare when I want to be, helped me realise these thoughts weren't real; they weren't the truth of the situation, just an attempt to sabotage myself.

And just like that, the voice has gone.

I did my 3 runs.

I'm back in the game baby.

Now I've announced the details of my new Grr Argh! Challenge, which will take place over a period of 9 weeks, I'd like to invite YOU to get involved by writing a guest post to appear here on my blog.

I want to hear about the challenges you've undertaken to improve your health and fitness. What made you start? What were the high and low points? How did you get on? What did you learn about yourself?

Maybe you can share your tips on how to keep yourself motivated when it comes to exercising and how you find the time to fit exercise into your life (especially if you're a parent of small children).

Or maybe you'd like to share the music you listen to when you exercise. Why did you choose it? What makes a perfect playlist?

If you're not one for writing on the topic of fitness, don't be put off. Instead, why not come and share your thoughts about the zombie apocalypse? Do you have an action plan? Have you picked out a safe haven? Planned some emergency supplies? Got your weapons sorted? I want to know!

Don't think you can't contribute because you're a newer blogger and you've never written a guest post before, you just need to be enthusiastic and I promise your post will find a happy home here!

If you'd like to guest post, please email me at ahellofawoman@gmail.com OR leave a comment and your email address in the comments section below so I can get in touch with you.
