Have a look at how far around Tim Andersen turns his head on these egg rolls LINK - he can easily get 180+ degrees from side to side - am flat out getting 120+ degrees from side to side ...... Am off to do some practicing.
With respect to the deadbugs result, it was @watchnerd that recommended doing Pilates 100s in another thread - I've been doing them most nights since February, 3 sets 30 seconds apart gradually getting legs lower and lower every month.
Damn that head position looks possessed! I have been doing a hollow body hold for time six days a week. It is interesting how you can still make progress with one set with high enough frequency.
