Bug (Bent Knee)
Bug Bent knee Leg Reach
Adding a leg reach starting from the bent knee position loads the hip flexors and challenges trunk and pelvis alignment1. As the thigh moves towards the horizontal plane, this increases the torque and difficulty1.
Note
Move as far as you can while maintaining your trunk and pelvis alignment1.
- Abdominal recruitment: Make sure you contract the abdominals, but be mindful not to let the leg reach decrease the contraction1.
- If you feel the abdominal tension decrease, then you have gone too far and have lost alignment1.
- Low back: Do not smash your low back into the floor1.
- Rather, focus on maintaining balance between the abdominal and low back muscles1.
- Do not let your thighs pass vertical towards your trunk1.
Bug Straight Split Leg Reach Position
Starting from the Bent Knee Bug, straighten your knees and begin performing alternating leg reaches1. As one leg is moving up, the other should be moving downwards1.
Forward reach
Holding a bug position then going for a forward reach allows the hip flexors to move through a dynamic range, while keeping the lower extremity stabilized.
Shoulder positions
- Maintaining shoulder retraction and depression is the most basic shoulder position
- T are a progression since they have an increased Horizontal abduction moment.
- Ws add complexity since it is a 2 joint movement, involving the shoulder and elbow.
- T-ERs or W-ERs are complex since it involves 3D movement of the GHJ of Abduction with external rotation.
- T-ERs have a greater horizontal abduction moment and less of an ER moment
- W-ERs have less of a horizontal abduction moment and a greater ER moment.
