the best advice you will receive, and the WORST ADVICE is this,,,,
you must learn to FLIP your WRIST, all distance is achieved with Ones wrist break, NOT their Bicep,,,
If youve ever seen pro golfers they all are 5'8 and weigh 160 pounds,, you need very little muscle to hit the ball 300 yards.
about 9 years ago I was watching an infomercial, "hit the ball as straight as you can point"
I think that was the name,,, that is the SIMPLEIST and greatest single video Ive ever seen,,
so lol, good luck,,
