I started Pilates after a huge Op to fuse my lower spine. I managed to recover all the rotational movement in my back but not the forwards (touch your toes) movement. Wish I had tried it years ago, before the need for the surgery.
Flying and driving are not what the human body were designed to do so you need to fit exercises into you day to restore your body to normality. I now have a £30 cross trainer device in the lounge to just get me moving whilst watching the TV or reading a book.
Pilates lessons, £5 per hour. Spinal fusion surgery, £12000. Loss of licence, painful.
