Thanks - appreciate the support from everyone on here.
Weights are something I've not really used but I have considered including them in my training of late especially as I've had to give up climbing/bouldering which I guess filled that gap before.
I already need to do about 30 minutes of daily physio which keeps my core in shape and strengthens those areas which these days, are sadly waning!
So I'll need to think through how I balance that with any additional weight training but definitely worth considering.
