HDogg, What the hell is DOMS??^^ Just Curious?^^
As for soreness, it doesn't matter if your sore or not. However, if your blasting your quads with 10 supersets each workout sesion, that's OVERTRAINING, I'm sure you know the common side effects of overtraining, muscle loss, loss of hunger, loss of immunity and so on. It's counterproductive.
Try to stay under 12 reps when working out. Don't go all out intensity with drop sets and supersets. They're good for when your having trouble with a certain muscle. They are just too taxing on your cns (central nervous system.)
I've been where you are now. I would do 1 hour just for quads and it would consist of Squats supersetted with leg extensions for 6 sets, followed by lunges supersetted with leg curls for 5 sets. Then would come stiff legged deadlifts for 3 sets, all being dropsets with a total of 3 drops for each set. Finally I would Do a 70 Rep dropset on my quads with leg extensions. The next morning my legs couldn't move. I was sore as **** and I was overtrained.
Try taking some extra vitamin C, Calcium, Magnesium and Zinc. It will help just a little bit.
Finally, what makes the muscle grow is to stick in certain rep ranges. Going past 15 reps will
activate endurance muscle fibers, giving you no added benefit as a bodybuilder. Hi Reps do not create more definition, a low bodyfat with a presence of muscle is what shows definition. If you are feeling sore or not it doesn't matter as long as you stick to the right rep ranges.
1-5 Reps Mostly for strength gains, Minor for Size gains
5-10 Reps Mostly for size gains, Minor for strength gains
12 Reps + Endurance
Hope it helps. Good luck Bud
