Higher Ground Reaction Forces... HIT BOMBS!
Ground reaction forces are a HOT topic these days in the golf world.
Bryson talks about them left and right.
The local pro has one of those cool pads that show you your center of pressure, weight transfer, and force levels.
And the strength coach on social media tells you how a squat is going to improve yours!
However, we need to dig a little deeper because it's not as simple as...
Step 1: Squat
Step 2: More GRFs in your swing
WHAT ARE GRFs
GRF stands for ground reaction forces, which are based on Newtons 3rd law.
I hope everybody out there likes physics... If not, we won't be here long, so you'll make it through!
Newtons 3rd Law states that when two objects interact with one another, they apply forces to each other that are equal and opposite.
For example, if I go push against a wall with 50 Newtons of force, that wall is going to push back on me with 50 Newtons of force.
Same can be said in your golf swing during your interaction with the ground.
When you are swinging a golf club, you apply forces with your feet into the ground, as depicted by the blue arrows in the image below.
Once we apply force, the ground pushes back up onto us (orange arrows), and this pushback is what we use within our golf swing to create force, and transfer a ton of energy into the ball!
When we bring rotation into the picture, it gets a little more complicated, compared to our wall example above, but the same principle applies.
