The steel club bullwhip is another great exercise for building shoulder strength, mobility and durability, plus, it combines the swing which engages the posterior chain.
Start the movement with a swing, then keeping your wrist neutral but relaxed perform a halo and bring the steel club a full 360 degrees around the head before casting it forward back into the swing.
Practice the bullwhip with a light club ensuring your head stays in a fixed position before moving on to a heavier weight.
Give it a go!
