I agree Fergus, bottom line it is all about recovery and your end point goal, as I mentioned on a post a wee while ago, one Christmas break I trained front squat 3 times per day on Mon/Wed/Fri and 2 x per day on Tues/Thurs/Sat and once on Sunday, the volume was low and the intensity varied but after a couple of days rest at the ed of this training week. my 1RM Front Squat went up 11% and my squat clean which I had not trained went up by 7%, cheers, ash
