I've been reading your column and I'm curious to know what you do for your own fitness

Currently far less than you might imagine, as I am recovering from an operation to remove my retrocaecal appendix.

However, on my road to recovery, I'm still applying the principles of training - build up gradually, work a little harder each time, be consistent with your efforts and, most importantly, get adequate rest for the body to benefit from the training.

Day one, post-op: From my hospital bed, foot flexing and pointing, and a few head turns were sufficient.

Day two: Progressed to arm circling and about 100 steps along the corridor, supported by my trusty drip stand and my partner.

Day three: I managed four small knee lifts with each leg, and three trips down the corridor - drip stand and partner still acting as training buddies.

Day four: I was able to introduce gentle knee lifts and leg curls from a standing position.

Week two: After being discharged from hospital, I am now tackling stairs and walking at a sedate pace - a far cry from my habitual 10,000 brisk-paced steps.

Week three: I was able to complete eight small pelvic tilts while lying in bed and, most importantly, I was able to laugh without tears of pain rolling down my face.

So, while I'm a long way from my usual fitness, the message is the same: it doesn't matter where you start your fitness - just start. And listen to your body: it deserves both your respect and efforts.
