I go for a decent walk most days and it doesn't require effort or get boring. It goes well with listening to headphones and relaxing the eyes on the horizon plus seeing a bit of nature and humanity in action. This does me a lot of good however the only upper body exercise I get is playing the piano! I can't see myself joining a gym or doing press-ups reliably in the long-term. I need to find a suitable hobby which has upper body + other benefits while being fun/interesting and low-risk. Carrying logs has helped but we have enough firewood now.
