The mid-week massage at the second hotel, provided by Tania, an excellent sports masseuse, was a great optional extra, but those of us who had it felt it the next morning because she had honed in and worked very effectively on muscles which wanted to be left alone !
Unless you have an iron will you won't lose weight on this holiday ! The food is uniformly excellent, homely authentic and plentiful. I have already googled Gazpacho Manchego amongst other things.
The walking is at the top end of the Moderate range. Some of it is definitely Challenging. Some certainly felt Strenuous (there are some big ups and equally big downs). Some of the descents, in particular, are on quite difficult terrain - loose scree/rocks/stones for example. A fair bit of the walking is through gorse or thorns so be prepared for some scratches, even if wearing long trousers. I would also wear boots every day - even though on the Thursday walk Jose said trainers would be OK.
