Our GP warned us about ‘bungalow legs’ when we moved here *honeypot’. Structured exercise doesn’t appeal to either of us. We walk as much as we can, use stairs in shops (when they are open), walk up hills no matter how slowly, walk a lot on the beach in soft sand. I have what I call my pedally thing, no room here for a full exercise bike so just the pedals. We both use it if we’ve not been able to get out. A physio advised using it from different seating positions to exercise upper leg muscles, can do it in front of the tv switching from a dining chair to the sofa. I think it’s very individual, find something you will be able to sustain. I’ve done yoga in the past when I could access a class specifically for people with physical limitations, sometimes do a bit of that but dislike doing it alone. Pilates interests me so may have a go at that once the virus permits. I’m sure people here will have all sorts of ideas, just try them out and see what works for you.
