In season, yes. It’s hills, sleds, med ball throws and jumps, simple plyos and jumps, and a few bodyweight exercises.
Off/pre season they do a simple (3-5 exercises, 3x5-10) lower/upper split four days a week (Well, maybe some of them, I’m not there off season so I don’t know who’s doing the work). That’s in addition to hills, sleds, stairs, and acceleration work. Don’t forget this is the Seattle area where if you don’t mind the wet you can be outside most of the winter. If it was really cold or snowy here we’d have to do more inside stuff i.e. weights but the way it stands right now the athletes get most of their leg development from hills/sleds/stairs.
