When training abs, and all of a sudden the amount of reps is just not benefiting as it used to (you've gotten stronger) what should you do?

- Should you increase the amount of reps: before 20 reps, now 30 reps.
- Should you increase the amount of sets: before 3 sets, now 4 sets.
- Should you add more weight: adding 10 more pounds to your crunch.

Does each solution have a different effect on your abdominal muscle outcome? If you add more weight, then the muscle becomes bigger and your gut may end up being just one big muscular 1 pack. If you increase the amount of reps, does it result in a more toned appearance, but less actual muscle?

Or is it better to perform different techniques?

What should be done?

Typically if you're using a weight that is no longer challenging, it's time to up the weight.

I agree to up the resistance. But when you're doing things like stability ball crunches, try placing your hands behind your head before you add weight to your chest. The only thing to be careful of is not to get too crazy with the weight when you're doing abs, while you do want them to be strong, you don't want them to grow excessively (it will appear like a gut).
