Over the last week or so, rumors have been swirling about Marshawn Lynch’s potential return to the NFL. The former Seattle Seahawks running back has been in retirement since February of 2016.

Lynch, who will turn 31 on April 22, visited with the Oakland Raiders last week. An Oakland native, Lynch informed his hometown team that he’d be willing to come out of retirement if they’d have him. However, the Seahawks still own Lynch’s rights. For Lynch to come out of retirement and join a different team, Seattle would either have to cut him or trade him.

There’ve also been reports that Lynch would be willing to sign with the New England Patriots if talks with Oakland fall through:

Marshawn Lynch update: He has privately expressed interest in playing for Patriots if talks break off with Raiders. Keep an eye on that.

Lynch was one of the most dominant running backs in the league during his time with Seattle. He’s a five-time Pro Bowler, a two-time All-Pro and a Super Bowl XLVIII champion.

It looks like Lynch is serious about his comeback. An Instagram video recently showed him working out with Los Angeles-based trainer Jamal Liggin:

Liggin’s client list includes a number of other NFL stars, among them Jarvis Landry, Odell Beckham Jr. and Alshon Jeffery.

Med Ball Slams are a great way for Lynch to build up his endurance and explosive power, two traits he’ll certainly need if he wants to once again be a dominant force in the NFL.
