Behind the scenes of Al Horford's training regimen

Tom Leyden welcomed Matt Martinelli to the FOX25 studio Saturday night. Martinelli recently sat down with Celtics forward Al Horford for a health and fitness featured in the latest issue of The Improper Bostonian.

Martinelli was given special access to Horford's training regimen and provided an overview of how Celtics' trainers prepared for Horford to join the team by traveling to Atlanta four-five days a week during the summer. During those trips, the Celtics learned more about what makes Horford tick and how he keeps his body in shape during the season.
