I would start a Foo Fighters radio. Can’t beat 90s rock/alternative.

Not sure if these are workout songs, but:

• Seven Mary Three - Cumbersome
• Eve 6 - The entire debut album or ‘Inside Out’ and ‘Open Road Song’ if you have to pick two
• STP - Plush
• Pearl Jam - ‘Alive’ but any song from their debut album
• Goo Goo Dolls - ‘Slide’, ‘Broadway’, and ‘Name’
• Valentine - Keep the Faith
• Anything by Nirvana
• Anything by Sublime

You didn’t ask me, but I’ll give you my unsolicited recommendation: Jellyfish - Spilt Milk

In a time when grunge was the new hotness, this band released a masterpiece. Catchy ass pop rock - like if you threw Queen, The Beach Boys and The Beatles all in a blender with some modern, polished sensibility. Dang just talking about it makes me want to relisten.

Although it doesn’t sound like it really came from the 90s to me honestly. Ok I’ll shut up now lol
