I must take my time. If I seem jerky when I start out, that's normal. It will lessen as I get moving. Two or three miles is good. Walk with me.
Company makes walking fun.
It may be a slow walk, but I'll get there. Remind me if I slump or stoop. I don't always know I'm doing this. My stretching, bending, pushing exercises must be done every day. Help with them if you can.
