Just did my usual HIIT routine - I do it 4 times a week - and it killed me! I’ve only ever sweat like that in a sauna before and everything felt 10 x harder. Does anyone know if there are any benefits to working out in the heat? Just to try to motivate me through it? I found it so hard to keep going. Any tips on how to keep cool? I think it’s going to be like this all week.
