i have been experiencing frequent back pain evry time i try to work my abs. weather it be crunches, sit ups etc. my back starts to hurt. i dont think i have a spinal problem but i do admit i sometimes get lazy and start slouching and its sorta of become a habit sometimes having bad posture. that may be a factor in my back pain. i can sometimes get through 10 or mabey 15 exercises until it starts to hurt or sometimes i cant even get through 5. i might be helpful to mention i am 15 years old. any comments/advice will be appreciated or alternate exercises.
