Same same, depending whether surfing or training. Was talking with a friend from AIS a while ago & she recommended using a T-Rack to assist with stretching and alignment of the back. 'Apparently' its used by many of the top swimmers and triathletes who've attended training courses. Its a simple piece of gear. It works for me...
(I don't sell them).

I'm lying here on my sisters tru back. It's a plastic rack type thing. 10 minutes max but you swop ends after 10 minutes. 20 all up. It works for me. Been doing it for two weeks. It's magic. Lots of different types. Check out the Internet. I must say supping is about standing in neutral stance and engaging your core. If you want to race then watch the Kalama videos and go to clinics like everyone here says. If you want to get fit without a sore back, Paddle from yours stomach muscles using neutral stance.

Hard to pin point exactly what it is without watching you paddle. A good physio / sports doc is worth their weight.

So there is such a thing?? Like a griffin I thought they were a mythical creature.

pilates is great for strengthening the core and rehabilitation!

I'm 41 and have suffered loads in the past with lower back pain, im 6"6 so leaver length is also an issue but over the last few years its not been a problem, when strengthening the core don't forget to work the transverse plane (twisting motions) as most of the time the back is hurt its twisted as well as flexed and we are only as strong as our weakest link, the Transverse abdominis is like a belt around your waist so you need to work all around your core, abs, back and oblique's as well as the twisting motions, this muscle helps immensely in supporting the spine.

personally I don't do full sit-ups as it puts to much stress on the lower back, crunches and leg raises are enough for ab workouts. IMPORTANT (when doing leg raises always keep your lower back pressed against the mat, if your back arches then make the exercise easier until you can hold your spine flat against the mat)

I've been a PT for a few years now and noticed that all the clients I've ever had with back issues also had a tendency to have tight hamstrings, these are very strong muscles that attach to your flat hip bones tilting them forward and causing lumber lordosis, stretch the hamstrings every day. and stretch everything after a workout.

last tip is always engage your core muscles, ie pull your belly button in, this will engage the TVA muscle and support the spine.

if all this doesn't improve your back then seek professional advice for sure.
