I haven't been very physically active since I got my cancer diagnosis nearly a year and a half ago. Before that, I regularly bicycled to work, about 12 km each way, and when I took rapid transit I'd often walk an extra stop or two past the closest one to get some exercise. Now that I'm back up to fighting weight (having regained the 25 kg—55+ pounds—I lost before and after my surgery last year), I'm making some efforts again in that direction.
But holy cow, am I inflexible. I've never been a yogi master, nor have I ever in my life been able to touch my toes. Still, yesterday when I took my bicycle out (the first time in months) for some errands and a ride through Burnaby's Central Park, I nearly fell over in our driveway, because my minimally-mobile hips almost prevented me from lifting my leg high enough to get on the damn bike.
Things improved some once I got rolling, and some of my stiffness was probably due to my Italian-sandal–induced wipeout a couple of days ago, but I also noticed that I really had to gear down the mountain bike while pedaling up even the slightest hill, and my speed on the flats was far from what it used to be.
I felt great when I got home, despite a bit of soreness, so I plan to ride some more in the next little while, particularly since I'm having a break from chemotherapy for the next few weeks. Some stretching would also probably be in order.
