shoulder dislocates, jefferson curls?

I am in the process of listening to coach's 2nd podcast interview with Tim Ferriss and came out with a question of what was said.

Coach and Tim talked about both shoulder dislocates and jefferson curls as something that GST athletes should be doing frequently.  However, in my 2+ months of training with F1 and Front Split Stretches I have not come across them. 

What gives?

Thanks!

Hi Natan, Jefferson curl is the MN progression at the beginning, dislocates it is included into Handstand 1 program.

Will have to get the handstand program then!.. Thanks
