Doing sit ups and/crunches hurt my back during and after the exercise, and if i do more than about 20-30 i get back aches for hours afterwards. Please help thanks.
I got a sit up bench from Argos http://www.google.co.uk/imgres?imgurl=http://www.argos.co.uk/wcsstore/argos/images/3027059A66UC291133M.jpg&imgrefurl=http://www.argos.co.uk/static/Product/partNumber/3027059.htm&usg=__lZQrnvZrv63K_c0ml9ysI3TJKSM=&h=300&w=250&sz=5&hl=en&start=0&zoom=1&tbnid=aQYz9iboYMQd3M:&tbnh=147&tbnw=140&prev=/images%3Fq%3Dpro%2Bpower%2Bsit%2Bup%2Bbench%26hl%3Den%26client%3Dfirefox-a%26hs%3DvGD%26sa%3DX%26rls%3Dorg.mozilla:en-GB
