My back occassionally plays up. Yesterday it did it again. I got that feeling that with every step, this twinge would go straight up the leg thru the back, resulting in me walking like a hunchback.
The day before that, I did go on a 3 1/2 Hour ride though (Which is longish for me). My shoulders have been a tight of late, so I had a funny feeling that my back may play up.
I find that I feel a slight hunch in the shoulders when I go for a reasonably long ride.
A cyclist I know, recently told me that my bike frame might be a little small for me. He just might be right. I'm currently riding a 2nd hand mountain bike, and it's time for me consider upgrading.
My back's on the mend now, and today I managed a short ride to the shops. I found that cycling at a easy pace, is much easier on my body than walking . My bike may be second hand, but I couldn't manage without.
