Pantera - Walk
Goodbye June - Oh No
The Score - Legend
Queens of the Stone Age (Honestly I’ve always liked basically all their stuff but for working out I have Sick Sick Sick and 3s and 7s, and Little Sister could be a good choice for you too, maybe even try Hanging Tree)
Blur - Song 2 (classic, nice and short too)
Korn - Here to Stay
Papa Roach - Last Resort
and a few Limp Bizkit (COME AT ME HATERS) namely Break Stuff, Nookie, and Rollin.

It’s entirely possible that I keep the last few bands and songs on this list because there’s a strong late 90s and early 2000s nostalgia factor for me and they may not be objectively good songs. But there’s an equally good possibility that they are amazing timeless classics that will propel you to newfound gainz. Probably the latter.
