I just started targeting my core today. Crunches and reverse crunches worked for me, but I need something to target my obliques. I couldn't really get a handle on the bicycle crunches or twisting crunches, but side planks seem to be good. Will side planks help in getting my obliques to show up? I have a very low BF, so that's not a problem.

Obliques don't have much potential for growth in the first place, but i'm not saying they can't grow. Side planks will hit the obliques, and its an excellen stabilization exercise.

What do side planks target? Are the obliques the main muscles being worked?
