Why do you squat and deadlift when you have a thin spine? Don't you know repeated heavy compressive loads is bad for you?

>SM: We've discovered that the shape of the disc determines its resilience to the number of bends it can survive with minimal collagen delamination.
>For example, while an oval-shaped disc with a smaller radius is better suited for twisting actions, it's poorer at repeated compressive loading. On the other hand, a limacon-shaped disc is better suited to bear high compression but it succumbs to focal stresses at the back of the limacon with repeated bending. This is exactly what's seen clinically.

GENETICS determines whether you should load up your spine with heavy weights. Squat and deadlift clearly isn't for everyone! Your spine is either thick/limacon disc shape or thin/ovoid disc shape, both are common. Little girls, skinny guys, manlets and retards can have a thick spine. Calling someone a pussy for not squatting and deadlifting is factually wrong!

Which type are you? Can you do situps without low back pain? Then you probably won't want to be regularly compressing your spine with hundreds of poundages of weight.
