Whenever I train legs, I'm severely sore for 4-6 days after. And not just a bit, I mean can't go up and down stairs sore, to the point it affects my work. All other bodyparts are fine, bit sore for a day or two, nothing extreme (my shoulders are never sore, no matter what I do to them) but my legs are so bad I can only train them every fortnight at the moment.
My routine usually looks something like this:-
Squats - 4 sets
Leg press - 4
SL deadlift - 4
Leg curl/extension superset - 3
Calves - 4
I always stretch after my workouts, and I take creatine, glutamine and BCAA's with my whey.
I'm not overtraining, I'm getting sufficient nutrition and rest, so what else could it be? Is it just genetics? (although it didn't used to be this bad)
Any advice appreciated.
