I got a sore shoulder trying to steer a toboggan with the kids on it. My chiropractor told me to exercise it. I bought a bowfit and it works really well. I try to get some push-ups in and do what the chart on the bowfit says. I’ll do while I watch the news in the morning and it’s done. The rest of my fitness is just walking the hills. Always was a better hiker than a runner and where I live the roads aren’t safe to bike.
