When I first started exercising I was taking tips of a 6ft6, 270lbs mountain of a man. Thanks to his advice I was going gym 5-6 days a week, for 1.5-2h each time. This left me very little time for family and friends, hence after about 4 months I switched to 4 days schedule and that's when I noticed better results.
I am currently working out Mon, Wed, Fri, or every other day if my schedule allows it - I am seeing even better results.
In my case less is better, but I guess it depends on your body type and your recovery abilities.
