Back to the Gym

Woke up early
& not intrigued by coffee
but rekindled by an old flame
I jumped back at the game

Hello Mr Treadmill
I have not seen u in years
and forget u, Mr push up bar
Don't think I wanna go that far

Hit this, hit that
I was ready for a workout
Turned this gym into a karaoke bar
Jogging singing to the top of my lungs

Sixty minute later
My feet started to burn
When I looked up the symptoms
 Wikipedia diagnosed it as a 'blister'
