I am a big dude. I can probably out lift a lot of disc golfers, but after watching Mike C's vids on youtube and one video with a dude in his front yard talking about snap, I noticed nobody was hurling discs the way I was.
I was literally pulling them across my body like I was trying to tow a truck. I was straining my arms, running up like a wild buffalo, and barely throwing discs 200ft.
I now throw with a motion that is smoother, thinking about hearing that towel snap and not flutter, and using a much more relaxed xstep. The gains are slow but are coming steadily. I can now consistently hit 250, 325 if I use dgcoursereview measurement standards and fish-story inches, and it feels like much less effort.
For me, which may mean absolutely nothing to everyone else, strength seemed to get in my way more than help.
