I would avoid hitting your heavy sets ie 295-315 for reps every leg workout. I made the best gains in strength and size by alternating workouts. Week one go for your heavy sets ie 295-315 for 8-10 then week two use 225lbs and do 4-5 sets of 8-10...week three go for your heavy sets again and youll find 315 feels easier. Many people have trouble doing this because they think they will lose size and or strength on the "moderate" day...this couldnt be further from the truth. I went from squatting 315 for reps to 660 for reps in two years using this method...and my legs went from 23" to 30".
