Anything would be better than nothing. If you see something that excites you, then I’d go for that.
What I’ve been doing is
A. Swiss-ball Crunches
B. Seated Knee-tuck (I’ve been using my living room table for this)
C. Hollow-body Hold*
I started with 3 sets of 20-30 seconds of work (not quantified by reps as I’m focusing on tensing my abs as hard as possible while performing the movements) and worked up to 4 sets of 50-60 seconds.
*Obviously not a movement but a static hold
Next I’ll either be doing this (see section 3)
Or, maybe take the first two exercises there as a superset and then do another superset with GHD crunches and swiss-ball crunches. I’ll let the realities of the gym dictate which option I pursue (equipment availability, how much time it takes, …)
Here’s another rotation I have bookmarked,
ABS WORKOUT 1
A1. Kneeling cable crunch 3 x 12-15 reps
A2. Machine crunch (use a 505 tempo) 3 x 6-8 reps
A3. Swiss ball crunch 3 x maxABS WORKOUT 2
A1. Eagle sit-up 3 x max
A2. Roman chair Russian twist 3 x 12-15 reps
A3. High pulley woodchop 3 x 12-15 reps per side
Any idea for what program you’ll run once you return back to the gym?
