We spend most of our time preparing for uphills. When going up, we need the power to overcome gravity. The force that keeps everything together on the lowest level. Let’s call this the status quo.
When going downhill, we use this force to our advantage. We speed up. We don’t need as much power. We need strength. The momentum could pull us in a direction we do not want to go.
Uphill we manage energy. Downhill we manage potential.
You can train for the uphills all you want. Behind every hill is a valley. You can reach the bottom ready for the next mountain, or on a gurney.
Channelling potential constructively is often harder than building power. Ask any rocket scientist.
