I could never give David Bernavich enough praise…being overweight my whole life and approaching my 40th b-day; I decided I wanted to change. I was given David’s name by a friend who trained with him and got awesome results! I signed with him in March of 2013 and have never looked back! 100+ lbs lighter and feeling better than I ever did in my 20′s, I look forward to my workouts; this coming from someone who has never stepped foot in a gym!
