Thanks for the thread, OP.
I was once very fit (cycled 35 miles a day on hills against strong coastal winds) and found gym sessions and running an absolute breeze.
Fast forward to now, mid-60s and have been WFH for 20-odd years. When I started self-employment I thought I'd keep up the exercise, but guess what, laziness took over instead (or rather, I prioritised work deadlines).
Having seen my parents' decline into helplessness, I'm determined to make more effort going forward, so that I can hang onto whatever strength and mobility is available to me.
I read about the inevitable decline of muscle mass as we age, but would like to hope that with plenty of walking, gradually easing into a bit of gentle running, a few Pilates/yoga sessions weekly, and a couple of weights sessions I should still be able to achieve some fitness goals. I'd also like to lose about 15 kg.
I have finally stopped berating myself for not making the progress I once did. This is obviously going to be a slow process. I just wonder what you think it's realistic to expect? Does muscle return if we try hard enough (without overdoing it)?!? Even when you start off pretty much from scratch again at an older age?
