Yes have read through some of his stuff, and Neill Stanbury videos as well. One of the issues I have is my rubbish core strength, and dodgy lower back Which makes that balance exercise kinda awkward. 😬
Plus I routinely swap between three roadies, which all have different setups. I should standardise on a few things like crank length and pedal spindle size to at least eliminate some of the variables, but where’s the fun in that??
I used to do core stability exercises in blocks over winter but found it much better to do a 'maintenance' routine where I do core stability exercises all year round,
I also found that the intensity of the blocks would leave me vulnerable and I had to watch when I went pedalling, so dialling it down to a couple of days a week where I use an ab roller and a bar (leg raises) and not a lot else and not at a high intensity (like the plank), I have slowly built up better core stability and now, the bike set up is not so critical whereas before, I would be ultra cautious about any changes - these changes were usually just maintenance requirements not bike set up. You know - 'i'd like to try that saddle but...' The lower back and neck pain got so bad during and after cycling, I thought I might have to give up. However, I then met my friend (which was fortuitous - my former physio whilst in hospital) sat a a café during a catch up as I hadn't seen him for a few years and he remembered my neck injury and immediately after I mentioned bike set up issues. said that he had noticed my posture as soon as he saw me.
So I set about improving my posture and I also added posture related stretching to my post ride stretch routine and that has been yet another step change in comfort. Sometimes, I just have a notion to do some posture related stretching. I have also managed to reduce saddle tilt. I now pay attention to everyday stuff - driving, moving, walking, sitting, working so I am consciously correcting the lordosis, my head position. etc I went the whole of 2024 without any major back issues and that's a first since 2009.
