Home core workout: ab crunch exercise

thanks so much!!

poor guy

thanks yo, btw nice body

Actually you shouldn't put your hands behind your head; you can place your hands near your temples or forehead so as not to put strain on your neck, or fold your arms across your chest.

I agree with the principle but not your implementation. The head is pretty heavy and the neck muscles weak so the head needs to be supported during the long duration of the crunches. The hands should only lightly push up on the head, just enough to support it. Personally, I find it difficult to provide enough upward force to support the head by putting my hands near my temples but everyone is different.

Thank you so much! ^^
