Proper training is an important factor in improving your game. An often overlooked aspect of golf training is the short game. Extra time at the range hitting the long ball is a blast; nothing will improve your game more than spending you time working on shots ranging less than 100 yards.
With any training regime, it is best to build a routine, and stick to it. Commit to spending as much time working the short game as you do the long game. If you have two hours to spend at the driving range, commit to spending an hour on the putting green.
Chip shots, shots out of the sand and approaches should not be neglected. A super human drive may be a thing of beauty but approach shots will win more matches. As best you can, replicate real world conditions during your golf training. Smooth sand and a ball perched neatly on time may make for a pretty out, but it is not something you will ever see while on the links. Toss the ball as straight and as high as possible and let drop. You get more out of learning how to dig it out. Drop your practice balls against the wall to learn how to handle tough outs; be that a big shot or the smart move to the side.
There has to be a park in the neighborhood that is not always trimmed on time. Train at rescuing your game from the deep salad. Not making it to the driving range is not a reason to skip training. If you spent an hour at the driving range this morning, then you owe yourself an hour of short game practice. A bucket of balls is the only equipment you need to practice chipping from the unattended edges at the park.
Your putter swing is absolutely the most important part of your routine training. Matches are lost and won on the green more than other sections of the course. Practice shots from inches to feet, uphill, cross slope and downhill while on the putting green.
You can practice in comfort of your own backyard too. Chipping from the well trimmed garden will only help you a little. Let the lawn go and extra week and you can get in a few light chips without damaging anything. Talk to the neighbor behind you and trade off hitting practice balls into each other's yard.
Metered practice will improve your game more than any elements of your golf training routine. Spending an hour, a few days a week, will pay off more that long stints on the weekend. Weekends are best-spent playing eighteen any way.
