Okay I've read a lot of posts and I don't believe I've come across this so sorry if its been discussed...
I started at this stuff a few months ago now and am making good progress. I can hold an L-Seat for 20 seconds and can actually get a slight upwards angle on it, not much but a little. I am also now on Tuck-Planche for a good 10+ seconds each rep.
My question is about my core.... I've seen very little improvements. My arms have gotten much bigger, particularly my triceps, but every post I've read says if you can hold an L-Seat you're going to have good abs. I also feel it in my upper legs fairly well. But m abs don't seem to be changing all that much. Any ideas why this might be?
