Focus on mobilizing and activating the hips and thoracic spine.
The first three drills are focusing on mobility. Feel free to add more repetitions if you like.
The latter drills are focused on activation, particularly around the hips and t-spine.
The breathing exercises (e.g. Supine Forced Exhalation and Half Kneeling – Sharp Exhale) – are to help activate the core, and to practice be up-regulating or down-regulating the core muscles.
