A Weight Lifting Option:

Though my gluteus is maximus,
The rest of me is laximus;
My abs and pecs have rested
Way too long as you can see;
Some muscles I am glad to meet—
Their workouts are a two-way street;
The more I laugh, the more I feel a lift
Inside of me;
A well-toned laugh can lift its weight
A hundred happy ways;
I'll work those muscles every day
To help me cast the blues away,
And lighten up my days;

Yes, I must admit
That I'm not as fit
As the girl I used to be;
While I might regret,
I mustn't let
Those thoughts get the best of me;
The best of me is yet to be—
So my hopeful spirit shouts,
For the part of me
That's the heart of me,
Still grows from the inside out!
