Moderate weight dumbbells, kettlebells, med balls etc make nice home training tools for golfers.
The main technique key is that as your hands move back your foot should start moving forward. The planting of the foot can then act as a trigger to rotate powerfully, before then having to decelerate.
Squatting, lunging, hinging, pushing, and pulling are the fundamentals, but we can also add some rotation exercises.
Ideally these would be done with a band, cable machine, or med ball throws but they aren’t always available.
Don’t let that stop you.
This exercise is benefical for mobility, strength, and balance.
Especially for those with lower training experience (gains get harder as we get more advanced).
It might even help you learn how to shift your weight and pressure a little better in the swing. Using a little bit of weight usually incentives athleticism.
