Someone advised me to read an excellent article, How to find your core. For me it has proved really helpful. I adopted this during my daily walks. During the first few days, it felt really strange, but like all things in life your body has an amazing way of adapting. Hopefully when I am able to start running again, it will help as well.
Pilates has been a saviour really, adding in core strength work as well has helped me try and reduce the muscle loss.
The muscle mass that has disappeared from my arms is alarming, specifically the left arm. I never really gave it much thought, doing various strength exercises regularly, like kettle bells and weights, carrying a bag with golf clubs during the winter, everything helped.
My arms now do not look like I own them. They should belong to someone at least 20 years older than me, and certainly someone who has never moisturised!!! It's come as a bit of a shock to see these crinkly things at the end of my shoulders! I will never be able to wear sleeveless shirts again.
A lot of people have said that as soon as I start weight training again the muscle will start to return, but can you ever undo crinkly skin, I don't think so!! If there is a secret out there please let me know urgently.
