I've been back lifting for about 3 months after a many year break. I'm 42 and weight 260ish. I run 3 days a week and lift 3 days a week breaking up the body into a chest / legs / back cycle. After my chest and back days I'm usually a little tight or sore the next day. No big deal, I know I've worked out. But on my leg days HOLY POOP! I am sore for 4 days, sore to the point I almost can't walk stairs. I'm not really "killing" myself on my lifts. I usually squat, leg curl, leg extension very basic stuff, 8 -12 reps 2 sets. I defiantly am not "maxing" out or really pushing myself that hard. But all this soreness is really hurting my running. Some days after my leg days I have to just walk my runs I'm so sore.
My questions are:
1) Is this ever going to stop? Why the hell are my legs and butt so sore?
2) Is this common for guys my age? When I was younger I'd get sore the next day but not 4 days??? Why just my butt and quads? Why don't I get this sore on my pecs, back, and Bi's?
3) Are there any supplements that might help reduce the soreness? I hate to sound like a Pussy but I'm really getting tired of being so sore.
