An updated list based on my current training
1. Superfly- straight body pull pass reverse planche before closing the hips and going into inverted cross
2. From German hang to inverted cross
3. Supermanna-the higher the manna, the stronger the element. Note- only pike reverse planche is a hold.
4. From a hang to reverse planche
5. Crosspossible- front lever to iron cross
6. From a hang to pike reverse planche(manna)
7. From rings support to handstand, back and hips surpass planche before pike. The higher the hips are before pike, the stronger the element.
8. From rings support to reverse planche
9. From a hang to victorian cross
10. Zanetti
Elements 1, 4, 5, 8, and 9 are dangerous to train without a professional. These elements require specially designed accessories for the lower body and hip. They are not elements, an athlete can develop like traditional muscle-ups.
