We all use strategies that work for us as individuals. It's always good to challenge ourselves, but some degree of enjoyment has to be there - otherwise we won't keep it up.
Some people who love Caroline and stick with her swear at her, curse her, hate her even - and then we carry on because it's an almost masochistic pleasure. She does what she does with a smile and a degree of enthusiasm which is very infectious and motivating.
We look at her and realize we'll never achieve her degree of fitness. But all the same it is so worth it. I hate her for the first few minutes, and then I turn into someone who does this for ME, and it feels great. I may be using half her weights, but I'm TWICE her age, and I'm doing it, and I know that my old age will be so much better than my mum's or my grandma's.
Looking in the mirror and liking what I see helps, mind. 😎
