just got in my bf calipers and it says to do a diagnal skinfold from the right nipple to the right armpit, vertical skinfold an inch away from belly button on the right side and middle of knee cap to top of thigh on right leg with another vertical skinfold. this is cool but i cannot seem to grip the skinfold regardless of how relaxed i am. its a pain in the ass. any suggestions on how to solve this problem or how about are there any other spots on the body to get an accurate bf skinfold measurement? searched for the answers and no results were found..
