Abstract: The football tackling training sled is a device that is used to train football players how to tackle during a football practice. The football tackling training sled is further defined with a backbone support that is attached to a base member via a spring-loaded counter hinge. The backbone support is encapsulated with a padding so as to be impacted via a user. The backbone support rests at an obtuse angle with respect to the base member. The backbone support includes a track, which interfaces with a floating t-bar. The user impacts the backbone support with a lateral force while the user drives the floating t-bar upwardly and along the track.
