have u watched all the episodes ?
I’d say the people who made it to the last episode are all pretty tough.
It was nt easy.
Arguably the challenges have got easier as it went on.
Now of the episodes have been too aerobically tough, although they was alot of carrying.
But the first episode (with the nazy seals) just had them jumping in and out of cold water tanks at night, then sitting in the sea etc
I know I could nt have done that, I’ve always found it you get wet and cold its very difficult to get your self going again no matter how fit + strong ur feeling.
