Workout wear that's not super tight?

[PuffinIsle]

Tops are not a problem but I really hate leggings or anything super tight. Any recommendations that are not those heavy jogging bottoms and also practical for the gym?

I have these from next: https://www.next.co.uk/style/SU771708/H59784

They're really light, just a thin jersey material. I've worn them for yoga, but mostly use them for chill days round the house.
