Arm of the Thrower

You also gain proficiency with improvised weapons, and can throw them a minimum of 15 ft. You can throw objects up to medium size this way. When you make an attack with an improvised weapon, the damage is based on its size, tiny objects and smaller deal 1d6 bludgeoning damage, medium objects deal 1d8. Additionally, when you attack recklessly, you gain advantage with one ranged attack you make with a thrown weapon on that turn.

Caber Toss

At 6th level your carrying capacity (including maximum load and maximum lift) is doubled, and you have advantage on strength checks made to lift, push, or pull objects.  You can throw objects of large size (provided they are not beyond your maximum lift amount) Large objects can be thrown up to 15ft, cost an action to throw, and deal 3d6+STR bludgeoning damage, any effects applied to ranged attack rolls also apply to this damage.

Wrestling

At 10th level, while raging, you can attempt to throw any creature you are grappling as an action.  A creature thrown this way is moved 15 ft in any direction (including up) and takes 2d6 falling damage when they land.  While raging, you can attempt to grapple huge creatures.

Master Olympian

At 14th level you have become a master of athletic arts.  Your minimum thrown range for improvised weapons increases to 30 ft.  When you attack recklessly you gain advantage on all attacks with thrown weapons during that turn.  The distance creatures are launched when you use Wrestling to throw them increases to 30ft, and the fall damage increases to 3d6.  Creatures thrown take this damage even if they collide with an object (such as a wall) before reaching 30ft.
