"...the hips are the engine"
Over the last couple of months, this point is really starting to sink in. Ben's 3 short vids on Lynn's site makes this quite clear. What made this crystal clear was watching Vijay warm up at the Canadian Open. He has this heavy club, that looks to be around 20-30lbs. It's basically a steel rod with a block of metal welded to the end. He would make a 2 part, slowmo practice swing with it. Take it to the top then let it drop to his side... pause, then using his hips he would drag the "assembly" through impact and fling it as far, down, out and forward, as he could. He'd do 4-5 of these then go back to ripping shots STRAIGHT down the range. Repeated with several clubs.
BTW: He is a freakin machine!! When he hits it, everyone watches, even the other pros!
