Came here to say exactly that. In general, abs are a muscle group you shouldn’t bother about in your workouts.

Do more complex, full body exercises rather than training such small, specific areas. If you do dead lifts, push ups, pull ups, squats etc. your abs will be involved everywhere implicitly and grow proportionally.

Crunches, curls, shrugs, shoulder press etc. that target small muscle groups are all only relevant if you want to max out an already well-trained body.
