CoreyMy job is based on physical performance.  To ensure I am in top physical condition, I train with David Allen at NBS Fitness.  I would recommend him and the staff at NBS to anybody who is looking to push themselves to the next level.  When my contract is on the line I put my fate into David’s training. That’s how much I believe in him and his staff at NBS Fitness.

The unique training I get from David each off season when I’m home in Memphis gives me a definite competitive advantage when I return to football each year. Each year he has helped me reach my goals, whether it was speed, strength, weight, endurance, or just working myself to the brink everyday.
