Random thoughts on solo drills

I need to collect some most basic solo drills

• Grilled chicken around the world (SBG name for safe posture on your back)
• Grilled chicken - single leg takedown
• Turtle - granby roll - grilled chicken - knee rule - crazy legs
• closed guard: grunch, hip bump, airoplane ( heavybag between legs?)
• shadow roll
• Ukemis all directions
• Kicks around the world (windmill drill)
• heavy bag
• shadow boxing - sparring
• deep stance - shiko-dashi ( 1 min hold?)
• Rope

• (Shadow sparring in three games: standup, clinch, ground? )
• What's the triggers? Reactions? Compinations? 

What is the purpose of drilling?
- physical attributes
- mental health (mindfullness)
- technical skills: - recall - automate routines ("safe postions" or home base)
