re: Paging HFB supplement experts

I'm not sure about supplements and there have been some good responses already. While I've improved my core in recent years and attempt to attack it from all angles (including squats, deadlifts, etc.), I recently did some jumps that resulted in a 72+ hour soreness in my front section of beltline.

It was one of those beautiful days and I felt like doing something outside after lifting so I went to an area that had three sections of 7 steps/each. After doing a few traditional runs up and down, I realized that it was a difficult challenge (I'm 40 with closer to 15% BF) to jump off two feet up to the third step and then use that momentum to make my 2nd jump even further to the top. I needed that adrenaline impact of realizing I could hurt myself to get the most out of that 2nd jump. I may try to add this as a twice/month thing to see if it helps my lower abs/core area.
