The biggest change in golf in the past decade is the focus on biomechanics, according to Gary Alliss, head professional at The Belfry in the West Midlands. "To be a great golfer, you need good core stability and very flexible hips, hamstrings, shoulders and triceps," he says, "so you need to work on that off the golf course. In the perfect swing, your hips should start to rotate out of the way, but your shoulders should be delayed. You can't do this if you're inflexible."
Focus on your feet
Spend time planting your feet properly before you swing. "They're your foundation," Alliss says. "Too narrow, and you'll be unbalanced; too wide, and your mobility will be restricted."
Modern club heads are deeper, so make sure your tee is high enough if you have a new club. "If you place the club head on the ground behind the tee, you should be able to see half to three-quarters of the ball above it," Alliss says.
Master bunker shots
They aren't as hard as they look, apparently. "If you were to put another golf ball down behind your ball, aim to hit the sand just behind that with a long follow-through," Alliss says. "You should end up with the club almost as high as after a full swing. They don't need to be as forceful though."
If you've got an ancient set of clubs, it's worth investing in new ones. "The modern driver, for example, is much more forgiving if you don't strike the ball perfectly," Alliss says. "And if you cannot afford a new whole set, replace your driver, putter and wedges, and always get them custom-fitted by a PGA professional at a golf shop."
