Like a cast into straddle stand on the bar.
For press exercises... it depends on your current strength and flexibility capability - here are some that aren't hard to modify harder/easier.
1. Straddle-L hold on parallettes or your preferred surface
2. Negative Press: Handstand, middle split, pike down to straddle-L ideally, straddle-stand is ok - slower the better. Can use a wall if you can't free-handstand
3. Press against wall from standing straddle: face towards wall, reach down to a standing straddle stretch, then lean shoulders against wall and press to handstand
