How much do the clubs and ball you use add to your distance? Does anyone do specific exercises to increase distance?
Equipment does help make some difference but swing technique is the key to unlocking more distance. Flexibility plays a large role in that too. Newer model irons can help golfers with a few yards and other things like getting the ball to launch higher. But they are not going to take a golfer that hits 8 iron 130 magically to hitting it 160/165.
The type of ball you play does factor in too. A guy with a swing speed of 75-80 mph will likely have better distance results with a ball with lower compression. Shaft flex as well. Lower swing speeds can benefit from graphite shafts and regular flex (or senior flex for older guys). Higher swing speeds benefit more with stiff flex shafts and higher compression balls (*insert joke here*).
I bought various types of balls to see if/how they affected my game. My home course is usually empty on Tues and Thurs afternoons and a good time for me to go out and not worry about anyone in front or behind me. So there are a couple of wide par 4s and 5s I can hit a few off the tee to compare.
I have Titleist, Taylor Made, Bridgestone, Callaway in my bag. I recently bought a box of the new Snell MTB balls (red).
Titleist:
ProV1(x).. top of the line balls. Love these but they are pricey.
NXT tour... nice ball, cheaper alternative.
Velocity... For the price, my favorite Titleist ball. High compression and pretty durable.
Taylor Made:
TP5.. top shelf ball but pricey.
Tour Preferred. Nice ball but I'm not sure they are best for my game. Lower compression.. not as much distance off the tee, imo.
Bridgestone:
B330.. love this ball and used to be more affordable but now getting up there with the proV1.
Callaway: Chrome soft. My least favorite of all mentioned so far. Feels decent for a few holes then turns crappy, imo. I know they've made improvements last year on this series but I'm not a fan.
Multiple hits from driver off tee: The Titleist Velocity consistently flew farther (for me) than any other ball listed above. Better than the Prov1 and B330. Although, overall from tee to green, they are both better performers than the Velocity. But at the price point, the Velocity is an excellent choice.
The NXT Tour is similar feel to the Velocity but slightly less distance in my view. Since Velocity is a little cheaper, I prefer it.. but the NXT tour is a nice alternative to change things up.
The Callaway, as mentioned above, finished last for me. I won't buy these balls again.
The Taylor Made Tour Preferred is an interesting ball. I hit it consistently around 10 or so yards shorter than the other balls. However, because of the lower compression (less side spin), it consistently flew straighter than any of the others. Even on shots not hit in the center of the face. Very forgiving ball. I feel like I can play this ball and I may lose yards off the tee, but I believe I'll have more shots in the fairway, which is kind of important.
The Snell ball, so far, has been excellent for me. It feels much like the ProV1, all the way into the green and feel when putting. At $15 cheaper per box than the ProV1, it could become my new ball to play. I've only played a sleeve so far though. But so far, I really like it.
My swing speed is 100-105 and at fitting, my ball speed with driver has been between 149-153 consistently. Stiff flex shafts and high compression (multi-piece) balls are what I play best. Although, I'm still evaluating the T-Made tour preferred ball. Didn't care for it at first but quickly realized that less side spin equals less errant shots... less lost balls.
RE: Exercises. I know there are exercises that increase strength but I submit that flexibility is more important than just strength. Like everyone else here, in my 20s I could just drive up and head to the first tee and press on. Now, I have to stretch several minutes to loosen my back and legs before the first swing. Some swing lube is also a big help.
But the most important element to increasing distance, imo, is the proper swing technique. The 40/50+ year old man who swings with mostly arms is going to hit an 8 iron around 130. When he learns to use lag and properly turn his shoulders/hips, he'll see that he can hit it over 150.
With that said, I know many golfers who are much better than me that are perfectly fine with not hitting 8 iron over 140. My brother hits 6 iron 150, and that is his choice. He slows his swing and hits a nice fade. I can't do that. I tried. He can hit it farther but has developed his game around that swing. Although I can beat him from time to time, he is usually 3-4 strokes better than me. Everyone's mileage will vary.
Sorry for the post length.
