Last summer, for the first time, I started to experience neck fatigue and pain at the base of my neck. This resulted in tension leading to pain between my shoulder blades. I had my fit checked and it's fine. What is not fine is my core strength and arm, shoulder, neck strength. I do a regular weight resistance routine. So, I was perplexed. A good friend who is also a physical therapist said quite simply, "Do more than you're doing." She was right. I've increased the number of repetitions, started increasing the resistance ever so slightly, and started adding an additional set of each series. Working on the core strength is pretty straight forward as well. I've just increased the number of sets I do. In just three weeks, I've already started to notice a positive difference. If I'm not careful, however, it plays havoc with the osteoarthritis in my hands, and the shoulder bursitis flares up a bit. So, it ends up being a bit of a balancing act.
I knew I would have to stay vigilant and keep working, but mistakenly thought I could reach a point and just "maintain" it. Live and learn.
So, what adjustments have you had to make with conditioning as you continue to age? Is what I've experienced just a freak abnormality?
