Jackknife Floor
Seated leaning back on the hands, one knee draws in to the chest while the other leg stays long, then they switch.
How to do it
Setup
Seated on the floor leaning back on straight arms, hands behind the hips, legs long and just off the floor.
Steps
- Draw one knee in toward the chest.
- Push it back out as the other knee comes in.
- Keep switching with the feet off the floor.
Common mistakes
Slumping between the shoulders: press the floor away and lift the chest. Feet dragging on the floor: keep them hovering. Rushing the switches: control each tuck.
Breathing
Steady throughout; never held.
