G&G Fitness has some family firepower behind it when it comes to their TV ads. This ad from the fitness equipment retailer owned by Gordy Gronkowski located in New York, Ohio and Pennsylvania features his sons Dan, Chris and Rob.

Rob posed shirtless earlier this season with adult film star BiBi Jones while she was wearing his jersey in a series of photos that lit up Twitter and briefly landed Gronk in the Patriots' doghouse.

BiBi apparently wasn't around last summer when this spot was produced, which shows all five Gronkowski brothers - including Gordy Jr., and Glenn - walking in tandem shirtless at the end.

Rob, Chris and Dan have NFL experience while Glenn is a fullback at Kansas State and Gordy Jr., played three years in the Los Angeles Angels' organization. Their dad, Gordy, played football at Syracuse. Rob, meanwhile, set the NFL record for most yards receiving by a tight-end for the Patriots during the regular season and scored three TDs in New England's 45-10 win over Denver last week.
