but a question first. What is the weight of the orange whip? Some research suggests that over speed ( lighter than club ) and overload ( heavier than club )components for REGULAR swings, should be no more than +/- 12% of your driver weight. This is because the weight must be similar to that of the club so that the swing will "transfer" ( law of specificity )
Studies also found that when players warmed up with a heavier implement than that which they would actually use - like the weighted "donut" baseball players use - bat speed went down! Also, though club head speed didn't drop as much for golfers, distance dropped due to off center hits. The best way to warm up is to swing your over speed club, or ideally hitting shots.
I always play better when I warm up properly - i.e. give myself enough time to get the old body warm and the juices flowing. ideally i like to hit balls, but I do just as well not hitting them and just warming up swinging my over speed trainer.
Read this thread about speed training
and if you want to cut through all the back and forth, you can just read Barrda's excellent post here about a program and tool he suggests for increasing speed :
His program as outlined in that thread works, I tested it, and use a version of it to this day.
The best speed training though, is the use of a speed chain if you can afford one.
Now how does this relate to MGS? Kiran has said that a "big swing" will get you more distance than MGS. I have found this to be true - about 4-6 mph more club head speed. But she also said that IF you stay in your MGS posture, you can go after it as hard as you want AFTER you hands/arms make a gravity drop til they are about hip high, then fire away. The idea is that most of the acceleration in the downswing doesn't occur until this point. We've all seen shots of Tiger stopping in the middle of his downswing when his hands are about waist high.
this is interesting because the speed chain is only swung 9'o'clock to 3 o'clock...it can't be swung any higher...so the chain is working the time frame in the downswing that matters the most...what the golf researchers and bio mechanics folks refer to as the "acceleration" phase of the swing. So with MGS, practice with an over speed club or speed chain using your regular MGS down swing and you will increase your distance. Just don't come out of your MGS posture as you speed train!
Never quit til you have a swing you'll never forget!
