Basic Backward Landing In All Jumps
This is a quote from a technical book I have on my shelf from my former days as a figure skater:
Practice a basic Waltz jump:
"You take off from a forward outside edge, and jump a half rotation to a back outside edge. Land with an erect back. In all jumps landing backwards, you land "toe-foot-knee" as though your leg were a free spring. The result is a smooth gliding land. Extending the free leg following through on the landing, is a very important part of any back landing jump."
Three Jump:
"This is one of the most basic and elementary jumps you will learn in skating. It is a half-turn in the air, from the left outside forward edge to a right outside back edge and many of the essentials in jumping can be learned practicing this jump. Always try to JUMP UP - NOT OUT. Jump from a well bent knee and land on one again smoothly. Get ready and be well balanced, but don't delay your jump for even a fraction of a second. Have your balanced toe turned out and pointed throughout."
Axel:
"The start of the take-off is very similar to the three-jump, but with the shoulders possibly more tense in preparation for the rotation, a turn and a half in the air. The arms are forcealby pulled in in a position like a one-foot spin. The skater then relaxes his body and prepares for the landing, which takes place on the left or opposite foot from the take-off. As he is coming down onto the ice on the left foot, the free leg is hanging out, forward, which, as he hits the ice, would be held back in a three-jump rotation
Practice both the Waltz jump and the three jump and I am sure you will master the axel.
I hope this helps.
