I am trying to zip up my core.
And keep it zipped.
All. The. Time.
It’s so bloody hard.
Does it get any easier?
This is not a metaphor.
Although, come to think of it …
No.
I just need to create more stability inside.
I’m lacking core strength.
There I go again …
That is all.

I hope this doesn’t sound Trite Alana but it’s not the winning it’s the struggle. It is trite but also true that a problem shared is a problem if not solved then at least articulated and therefore at least capable of being managed. paradoxically articulating your insecurities actually begins the process of creating stability (i know this from personal experience). Perhaps zipping up is the wrong (it’s not a) metaphor. perhaps what needs to happen is a process of managed aeration. in any event you’re dealing with it.
I don’t think you are lacking anything my love.
Core strength is what I don’t have when I do the plank on a Pilate’s reformer! Funny but there they talk about zipping it up, too.
The plank! I HATE the plank soooo much.
