Couple of things got me started. Firstly, I had an issue with damaging my legs, tore up my knees tripping, got trochanteric burstitis in one of my hips, and shortly after that, my mother broke one of her hips and I had to look after her to a degree. I didn't feel I was quite upto the job. She often needed lifting, or total body support, and often, carrying her weight as much as my own was nearly too much. I've never been a sportsperson, never got the idea of competitive nature and have worked for a long, long time in a very sedentary job. The issue with my hip prompted me into physiotherapy where I realised I was pretty physically weak and I realised I probably had been for quite sometime. Coming back into contact with my father after 30 years, I was really shocked by his physical shape. He's 80 now, but at the wrong end of 3 heart attacks, which obviously impacted his ability to keep in shape seriously and he looks frail, nothing like he was when I was young. It made me think "I don't want this for my future". When I get to be 80, I want to be built like the side of a house.
The feeling of progress. The feeling of being in control of my own life and future. The reassurance that I might not be totally washed up. Being able to look at myself and say, "I look better than I did a month ago". Being assured of my own physical strength. My missus really liking my butt.
