re: Avoiding leg day post-soreness

Honestly depending on how long you've been working legs will decide your soreness. I see for the past 3 weeks it's been rough. So if you're jumping into a program that has you working a lot of reps/sets on legs; and you haven't really worked legs, in lets say 2-3 years, you're going to experience that awful soreness for a while.

I would look at the program. Start off small. Cut the reps and sets almost in half and really watch the weight you use. Condition your legs before really going in. Stretching will only get you so far. Soreness is from breaking the muscle down and it's repairing. A stretch won't help too much. Hydration will help, walks will help, and if you can swing the price, a muscle stim product will help. Blood flow is key.
