My fellow Josh, I pair my statics. I actually filmed it not that long ago, so that I could put it up as an example. I just haven't edited the film yet.
I do straddle L and FL together, so I'll do one 20-30s set of straddle L( bent), then a 20s set of advanced tuck FL. Usually not 90/90 unless I'm feeling super good. You'll be surprised how far below your max you can work and still actually make good progress on strength. After two rounds of that I'll usually take 30-60s breather, then I do planche and manna which translates to advanced frog x 30s followed by 60s reverse push up, followed by another 30s advanced frog. Then I take another minute breather or so, even though I'm not particularly tired. Last up is German Hang(back lever pre-req) and L-sit. I do 30s German and 20s L-sit.
Sometimes at the end of the workout I'll do one more set of FL and L-sit, if those muscles weren't wrecked. Today ( August 5th), I will not be doing a third set of FL because this is a pulling workout and I don't think it's necessary OR particularly helpful.
