I have just started skydiving, and am having trouble with my Arch. I have a few minutes in the windtunnel, and am having trouble staying stable. When going back to look over my tunnel videos, I noticed that I really do not bend my legs. Looking at people who have been skydiving for a long time, their knees are bent at about a 90 degree angle. The problem is that anytime I try to bend my knees more I start moving forward. I am starting to get a little discouraged since i cant figure it out, and am looking for a little advice/ seeing if anyone had the same problem starting out and what you did to fix it. Thanks!
