I'm doing hang-board workouts. A series of pull-ups, dead hangs, bent-arm hangs, l-lifts, off-side pull-ups, on different holds - from jugs to three fingers. (It has a two finger hold, but I can't use that, my fingers won't hold me.)

Between each set of hang-board things I do sit-ups, push-ups, Mason Twists, bicycles (forward and backward), and crunchy frogs. It takes about 30 to 45 minutes to do the whole thing with a stretching cool down.

I'm always completely beat afterward, and my longest dead hang is 15 seconds! EGADS! I'm a wuss. (grin)
