This is the Long Toss program for Russell County High School of Seale, Alabama, as developed by their coach, Tony Rasmus.  From p. 16 of the 1 Oct 2005 issue of Collegiate Baseball:

     “We line up our players on one end of the football field on the zero yard line. After they are thoroughly warmed up, throwing partners move back gradually to the 30 yard line where we start getting serious as each player performs eight firm throws.  Then throwing partners go to the 40 yard line.  Eight throws are performed once again.  Then they  move back to the 50 yard line and continue going back 10 yards at a time until they are at the zero yard line on the other side of the field if they can throw that far, keeping in mind they throw eight times at each distance.

     “In the beginning, the maximum distance kids can throw is about 70 yards (210 feet). I am not too concerned with the trajectory of throws. Some tend to rainbow the ball more than others. I realize different coaches will argue that all balls should be thrown on a line to work on the proper release point.  But over time, these kids get stronger and stronger.  My son Cory can stand under the goal posts and throw balls through the goal posts on the other end of the field.”
