![]() ![]() ![]() If I understand this correctly, at our level (beginner) the legs and arms come into play to create "horizontal" (turning) stability, whereas the hips/belly/chest are what connects to the "column of air", and creating "Vertical" (up/down) stability (I know what I mean, just having a hard time articulating it). and then practice your arch over and over and over and over and over and over. Look at some of the AFF photos in the gallery and see what I'm talking about. Then try lifting your legs off the floor.and feel which muscles are working. ![]() Try laying flat on the ground, and lifting your shoulders off the floor - without using your arms. If you lay flat on the floor, and then arch (not a creeper or anything elevated), you should be contracting the lower back and butt muscles, and not using the leg or arm muscles to create the arch. From what I understand, and from what my body says, the leg muscles aren't used at all.it's the contraction of the lower back and butt muscles which create the arch. My problem was my arms - stuck straight out and rigid.the solution I was taught was to be able to see both hands in the periphery of my vision at the same time while in freefall.and when I remember to do that, I don't rotate.īut about the part I snipped and quoted. I am not an experienced jumper, and likely shouldn't be offering any advice.and the most important thing is to talk to your JM's, and learn from them, as they have seen you on the ground and in the air. I feel the reason is because on the ground my leg muscles are pulling against gravity, but up there they are pushing against the 120mph relative wind. Be advised that we don't have any wind tunnels in this country which I feel would be my best course of action. Any advice or comment from you guys in the meantime would be appreciated. I feel the reason is because on the ground my leg muscles are pulling against gravity, but up there they are pushing against the 120mph relative wind.ĭue to deteriorating weather conditions I have some considerable time before my next jump. In a dirt dive I am told that my leg position is OK and should be good enough for a stable fall, but I'm having difficulty translating that to freefall. He says it's just a case of needing practice and developing the muscle memory, but personally I would prefer to nail the problem before going back up there for Level 4. This jump knocked my confidence a bit, so I was surprised when the instructor said he would clear me for Level 4. The chute opened with no problems and I drifted down safely. I realised that he had pulled my ripcord. A second or so after that I felt the G's kick in and saw the instructor fall away from me. Unfortunately the instructor still had a hold of my arm so I couldn't. ![]() I checked the altimeter which was 500ft (3 secs) away from the hard deck of 5500ft and I made the decision to pull. I seemed to adopt a flat spin which wouldn't stop no matter how much I tried to arch. As much as I tried to put the arch on, I couldn't get stable. (He grabbed the arm because it was the only part of me he could reach due to the relative velocity.) This is when things started to get a little hairy. He then caught up with me and grabbed hold of my arm to stabilise me. On the second attempt I had solved the rotational problem and I was stable enough following the release of the Secondary JM, but as soon as the Primary JM let go, I backslid away from him due to bad knee position. I felt relief when the altimeter reached 6,000ft and pulled my main. This instability seemed to get worse and, although I arched as best as I could, I started to rely on the Jumpmasters to keep me stable. I knew it had something to do with my arch but my mind kind of lost awareness of my leg position. Up there though I felt so unstable and I was rocking about all over the place whilst turning to the left. On the first attempt I was having major problems with my legs as I was to discover in the debriefing. I have finished my second attempt at AFF Level 3 and I still have a stability problem. ![]()
