I've been reading a bit on here about planks and I actually used to do side planks (I called them side bridges) a few years ago but was always a bit unsure about how valuable they were.
As I've been doing some searches on it, it seems like a lot of people recommend the regular plank (on both forearms) for core strengthening and abs.
My question is, how do these exercises affect the physical appearance of the body? If someone that's been doing crunches already adds planks to the end of their workout, will this help them develop bigger abs, tighten up their stomach, what? Or is the purpose just for core strength to help stabilize for larger compound exercises? What about side planks/bridges? Do people who perform planks generally do just the regular planks, just the side planks/bridges, or both?
Thanks for the help guys.
