Alessandro -
You requested that I post this in F4, but I think this is the appropriate baord as SL SE1 is an F3 exercise.
Could I get a little more guidance on SL warmup? I just moved on to SE1, but had only been warming up with a set of RLL in a headstand against the wall. This should have me covered for back extension, but I'm looking for good options for spine rotation and side flexion. Do Windshield Wipers fit in for rotation? What else might you include from the PEs specifically besides RLL?
Thanks in advance -
