This exercise develops the strength and muscle control necessary for performing assemblés at a jump's peak. It aims to develop muscle memory in a non-weight-bearing manner, helping students move to floor exercises with a better understanding of the movement.

Preparation: Ensure students are lying on top of the fit ball in demi plié, with feet flat against the wall in 3rd or 5th position. Check that knees are aligned over toes. Hands should rest on the floor, slightly forward of the body, with soft elbows.

Steps:

1. Guide students to perform an assemblé dessus, sliding their back foot along the wall and bringing it back to join their legs at the peak before landing through the metatarsals. Follow with a soubresaut (sous-sous).

2. Instruct them to repeat, leading with the left leg.

3. Once comfortable, introduce the assemblé dessous and a soubresaut (sous-sous).

4. When secure this can be follow by a changement battu (royale) and entrechat quatre. Or without a beating action.

Focus: Monitor that the spine remains elongated throughout, and the fit ball moves smoothly forwards and backwards.
