Improving arching and rounding spinal mobility.

Goal is to improve spine mobility:
What are your thoughts on supersetting this progression: https://www.gymnasticbodies.com/forum/topic/181-developing-active-back-flexibility/
with Jefferson Curls?

I'd be doing the routine everyday; would a rotation movement be necessary?

Also a quick question on press HS mobility. Would Jefferson Curls alone provide enough hamstring mobilization for Straddle and Pike Press'?

Your link is broken. 

Mobility work every day is almost always going to be too much. You won't benefit from doing more than 2-3x/week for most things.

Jefferson curls will provide necessary hamstring mobility. However you'll have to develop pancake flexibility separately.

Just re-edited the link.

Ok so I'll lower the volume then.

Right now my routine looks like this:

Day 1:

Press Handstand Progression

Front Pull Progression

Day 2:

Olympic Back Squat

Hill Sprints

Day 3:

Hollow Back Press Progression

One-Arm Chin-up Progression

Day 4:

Bridge Pull Progression

Jefferson Curl

Repeat cycle.

I can realy recommend the thoracic Bridge series for your needs.
