Verse
Treadmill lights and you walk right past me
Six a.m. and my heart rate's already
Racing hard before I hit the floor
Grabbed the weights but I can't ignore
Your laugh cuts through like a drumbeat
Chalk dust rising off the concrete
Mirror wall throws your smile back at me
Now I'm moving to a different rhythm completely
Pre-Chorus
Can you feel it climbing, climbing in my chest
Every rep is a question I can't rest
Is this the burn or is it something more
Cause I've never felt my pulse hit the floor like this before
Chorus
It's firelight cardio, running through my veins
You're the reason my heart's outrunning the pain
Sweat and sparks, I'm caught up in the blaze
Firelight cardio, I'm falling for your flame
Feel it burning, burning brighter every day
Firelight cardio, I'm never turning back this way
Verse
Water break and you toss the towel
Say my name like the room got louder
Kettlebells swing but I've lost the count
Watching how you move, that's what it's about
Locker room talk turns into laughter
Now every workout's the one I'm chasing after
You spot me steady, I hold my ground
Never knew a gym could turn this whole world upside down
Pre-Chorus
Can you feel it climbing, climbing in my chest
Every rep is a question I can't rest
Is this the burn or is it something more
Cause I've never felt my pulse hit the floor like this before
Chorus
It's firelight cardio, running through my veins
You're the reason my heart's outrunning the pain
Sweat and sparks, I'm caught up in the blaze
Firelight cardio, I'm falling for your flame
Feel it burning, burning brighter every day
Firelight cardio, I'm never turning back this way
Bridge
Forget the numbers on the clock
This ain't about a personal record I've got
It's the way you breathe my name between the sets
The only high I'm chasing, the only bet
Chorus
It's firelight cardio, running through my veins
You're the reason my heart's outrunning the pain
Sweat and sparks, I'm caught up in the blaze
Firelight cardio, I'm falling for your flame
Feel it burning, burning brighter every day
Firelight cardio, I'm never turning back this way
