It’s utter nonsense that she thinks the sweat proves she did a good workout. Jillian Michaels uploaded a really good video about it this week (I know she can be a bit problematic but it was a really interesting video) basically if the reason you’re sweating is coming from external factors (hot room/hot clothes) and not internal factors (like actually physically exerting yourself) it means fuck all. And actually the dehydration it causes can be detrimental!
