Free 4.28 Speed Manual

We are in the process of updating our 4.28 40 yard speed manual, which details

everything I did to take my 40 yard dash from a 4.66 to a 4.28. It also has

what it took for me to go from the bench to starting. It details my workouts, speed program,

strength program, agility, recovery, etc...Since we are changing to the new version I wanted

to share the strategies I used on hundreds of athletes from pop warner to professional to

the o-line world members. Send me an email at strengthchamber@gmail.com and I will send you

a copy of the book. Thanks.
