I was working on my hitting motion this week and found that when I focused on my hands swinging past my chin before I fired the hips, I could really 'snap' the hips and thrust the right arm from impact to separation.
Perhaps what some have called the 'launching pad', which for me was very much felt as left hip and right forearm synchronized power through impact.
Ed, trust me when i say you'll know if you are using the launching pad to the full effect when it happens.
It LITERALLY feels like someone pushed you in the right shoulder (backwards) going through impact.
