Pre-reqs are static positions that you should work to develop the foundational strength necessary for more advanced Gymnastic Strength Training™. While you might already be physically capable of performing some more advanced strength elements, it is important to master these prerequisites first because they will help to prevent injury. They will also help you to progress further, faster.

3x60 of:
- Hollow hold
- Arch hold
- Plank (with straight arms and scapular protracion)
- Reverse plank (In arched position)
- PB support
- Dead hang
Then the "next level" would be
3x30 of:
- L hang (helps FL)
- German hang (for BL)
- L-sit (for PL)
- Rings support (shoulder and biceps prehab)
After mastering this very basics you can expect to actually progress in the traditional FSPs such as PL, BL, FL V sit, straddle L and so on
