Workout
For these three developmental positions with movement I utilize a mini band above the knee as well as a core360, which cues interabdominal pressure, the postural function of the diaphragms and helps me maintain abdominal synergy.
In the first exercise I am in 3 month position, the mini band reminds me to slightly externally rotate the femurs. As I extend and flex the hip; I maintain the angle of the knee and ankle joint.
Next I transition through the developmental progression (side lying, low oblique sit, high oblique sit) into big bear. Maintain uprighting of the spine and simply (!) bend the elbows. Think of bringing the elbows toward each other. Keep slight pressure into the mini band
Finally push yourself away from the ground into a squat. Stepping side to side.
