I saw this on another site and just had to share

O Fitness Tree, O Fitness tree,
How lovely are your crunches!
In downward dog, your strength will grow
Through bootcamp and running in snow.
O Fitness tree, O Fitness tree,
How lovely are your crunches!

O Fitness Tree, O Fitness tree,
You are the side-plank we most love!
How must we work to make our abs tight
We need to learn to do it right!
O Fitness Tree, O Fitness tree,
You are the side-plank we most love!

O Fitness Tree, O Fitness tree,
Your jumping lunges will teach me
That strong cores & glutes will ever be
The way to shrinking jeans for me.

Your jumping lunges will teach me.
