Whisky in the Jar - Metallica.
Dunno what it is but its always done it for me. Solid song to the beginning of my workout. Ear buds, turned up full boar to ear bleed levels on 3peat, blood pumping, I get a 20min sprint on the treadmill out of it. Been doing it for years.
I really like Metallica, but I love Thin Lizzy. Classic song.
Have a look at the Metallica film clip…
The song itself dates back to the 1600s however. Give or take.
