Haha at first I read the title of this thread "Office Ice Jumps" and I thought it related to jumping at work...I used to do mine by the copier lol!
Try keeping your arms tight, bring them against your body and let your legs do all the work.
Start by jumping in place with no rotation, feet side by side. Then do 1/4 rotation, again letting your feet do all the work (arms tight & tucked, feet side-by-side). Do each direction. When you have that, go for 1/2 rotation, then 3/4, and finally a full rotation. At this point, don't worry about crossing your legs-your focus is height & rotation using your legs.
After you have achieved this, and give it time (several days per week for one week should do it), advance to arms in jump position and pulling in, again feet are not crossed but side by side. And once this is achieved, the final bit is crossing the legs in addition to using your arms.
These are standing static jumps-no entry steps are needed. For loop/flip-feet will be lined up as for those jumps (one in front of the other, weight more on one than the other). Again, it's a progressive exercise where you build from the simplest to the most difficult. If you don't get the beginning part, the harder part will be more difficult.
Try this and see how it works for you.
