Hello everyone. Im new to the fitness world and would like some advice on where to begin. Im 40 yo, 5'4" 135. I want to become more fit but I have some medical problems to contend with. I have mild scoliosis at the top and bottom of my spine. A car accident 15 years ago made it worse. I also have lordosis(tail bone curves too much) Three partial fusions in my right ankle from the car accident. Also I have a flat neck from the accident. Lastly osteo arthritis thoughout my body. I thought about starting p90x, but I dont really want to lose any weight. I would like to start weight training to strengthen my body but I dont know how to begin. Any advice on a program I could start with would be greatly appreciated, thank you.
