Sit ups can be really hard on the spine, even if done "properly". You slip a disc in your neck even slightly while working on your abs, and you won't be working on your abs or anything else for a long time. Slipped discs can cause an astonishing amount of pain. Not an exercise guru, just someone who slipped a disc. |
