Perhaps you could demonstrate with appropriate Classical mat exercises how to keep out of the low back. That would be most helpful. Don't have any apparatus. Thanking you.
Yes! so important those back extensions. For me, the best way to teach and so to make my people understand and feel, is : "The distribution of the movements is equal to the distribution of the forces and vice versa". That creates as well harmony and safety in the move. Tks to Brend!
