This is coming from an NFL Hall of Fame Running back, 4th all time rushing (soon), who just a few days ago, had his NFL team on his back running for over 100 yds in blizzard conditions, in like ten feet of snow, in freezing weather. At 34 years old.
Let that sink in.
That shlt means something coming from him.
And they haven’t even started on the strength, nutrition and conditioning program yet. Let that sink in.
