friday saturday and sunday are days off except for running

so is there anything i am doing wrong? am i overtraining? i make sure i set all my exercises to a weigh were i cant do more than 10 reps when going to failure which is what i do...go to failure on all exercises except squat. i have 7 days rest before i start the same workout again. should i alternate between light and heavy training on the weeks? well any comments and suggestions will be apprieciated thanx guys

too much volume on chest and back (overtraining) and the pullups, pulldowns to the chest and pulldowns to the back are all working the same muscle. yes on alternating light and heavy weeks.
