Sorry to hear about your FIL, @BezMills
So far as I'm aware, all the Cooncil gyms round my way are completely shut on the Wednesday, Thursday and Friday. The cafés in the Cooncil gyms round here are all shut for the fortnight, but the water machines and coffee machines are working. Some of the private gyms might be open, but I'm too much of a skinflint to enquire.
The only class at my nearest gym which is currently showing spaces is the Senior Flex.
However, there should be plenty of space in the new weight room. (Used to be Studio One - it's right next to the refurbished gym.)
The early morning bootcamps at all the gyms always seem to have space, but the one at my gym seems to be outside. No thanks! Too cold for me!
I'm booked into Pilates tomorrow and Stretch on Tuesday. Apart from that, I think I'll try to get onto some of the new machines in the refurbished gym and maybe use free weights for the upper body. I admit that I'm missing the structure of my classes.
