Sit-ups used to be the gold standard for getting those strong, chiseled abs, and still have a place in the strength and fitness world; However, research has shown that planks are actually the dominate core exercise people should be concentrating on for overall long-term core development.
Reason 1- Sit-ups are more of an isolated core exercise that generally targets the rectus abdominis, or notably the 6-pack abs that are readily seen in most of the fitness model profiles on Instagram. There’s absolutely nothing wrong with that. Who wouldn’t want to look like they were chiseled out of stone? However, the rectus abdominis represents only a small part of the total core musculature and concentrating solely on these aesthetic muscles could present functional health problems down the road.
