There sure is some youngsters on here, legs are good and so are the other systems here in this 1956 model. Mind you a trapped nerve in the back is going to play up for a few weeks.
Ha ha - another 1956 leg-owner here! (And my back was twinging earlier in the week after rushing into some exercises with 2 x 7.5 kg kettlebells. I think I will build up a bit more gradually with those!)
I have only done about 1,800 miles on my bikes so far in 2018 after a slow start due to the extended winter, but I am catching up on my goals fairly rapidly now - another 70+ miler is planned for tomorrow in the Yorkshire Dales.
In terms of cycling, my legs are working better than they have for a long while. The left leg looks a bit of a mess though due to its damaged veins. Normally, it is covered by a compression sock but it has been too hot for that recently.
