Hi, I'm just coming to the end of my first week of Fundamentals. It's been going well but I have a question about the tuck position - in order to get my knees close to my chest and have my back straight, I have to really pull my legs hard with my arms, so it feels like the part of my body that is working hardest is my arms and shoulders.
Is this right, or should I relax my arms a bit and have my legs a bit further away from my chest and use my core to keep my back straight?
Thanks, James
