I also like Bette Midler's "I'm Beautiful, Damn It". Its a great workout song AND has empowering lyrics

"BIGGER THAN MY BODY" by John Mayer

"cuz I'm bigger than my body gives me credit for...."

Two Garth Brooks songs, The River and Standing Outside The Fire.

The River

I will sail my vessel
Til the river runs dry
Like a bird upon the wind
These waters are my sky
I'll never reach my destination
If I never try
So I will sail my vessel
Til the river runs dry

Standing Outside The Fire

Standing outside the fire
Standing outside the fire
Life is not tried it is merely survived
If you're standing outside the fire

I'm not a big country fan but I do love Garth and those 2 songs especially.

I've been using "Float On" by Modest Mouse as my "theme song" lately - just a reminder to not beat myself up if I don't eat perfectly, and that everything will work itself out.

I backed my car into a cop car the other day.
Well he just drove off, sometimes life's OK.
I ran my mouth off a bit too much, oh what did I say?
Well you just laughed it off, it was all OK.

And we'll all float on OK. And we'll all float on OK.
And we'll all float on OK. And we'll all float on anyway.

Well, a fake Jamaican took every last dime with that scam.
It was worth it just to learn some sleight of hand.
Bad news comes, don't you worry even when it lands.
Good news will work its way to all them plans.
We both got fired on exactly the same day.
Well we'll float on, good news is on the way.

And we'll all float on OK. And we'll all float on OK.
And we'll all float on OK. And we'll all float on.
Alright already, we'll all float on.
No don't you worry. We'll all float on.
Alright, already. We'll all float on.
Alright, don't worry. We'll all float on.

And we'll all float on.
Alright already, we'll all float on.
Alright, don't worry even if things end up a bit too heavy.
We'll all float on.

Alright already, we'll all float on.
Alright already, we'll all float on OK.
Don't worry, we'll all float on.
Even if things get heavy, we'll all float on.
Alright already, we'll all float on alright.
Don't you worry, we'll all float on.
We'll all float on.
