Ring series question!

Wazaaap guyzzzzz!

So I'm a little curious about the ring series (if i ever get there one day lolzz), I have absolutely no clue about what strength skills it gives?

i read about the iron cross in r3, but what about stuff like maltese for instance? Is it in the R-series too?

Whatelse does it progress towards?

ThankZZZZZZZZ

P.s. Don't mind all the "zzz" haha I'm really tired right now xdd

Cross, maltese and inverted cross on the straight arm side. Inverted muscle-up on the bent arm side.

En route you can expect assorted cross pulls, and combined pull-press, from muscleups throughGalimores

Nb-

Extrapolation, but seems a safe bet

Pretty nice
