I'll start by saying I have MS but I'm an ex runner. I've had a long period of ill health and have suffered from muscle loss.
I used to be very strong and toned. Fit and able to run 10km and row well. I was at my absolute fittest during covid and I ran 5km every single day.
I think I'm ready to get back into shape. And I was wondering what I should be doing?
Strengthening / straightening my spine is my priority as my back hurts (low level but getting worse) and my posture is bad. I have no core muscle.
Is it running? I also have some 4kg dumbbells.
