I joined this forum because I was searching for this particular problem.
I have recently got back into Golf (after taking 3-4yrs off after a broken ankle). Anyway, I needed to lose some weight and walking Golf was better than just walking. I started eating right and getting a minimum of 12K steps per day (more on Golf days). I've lost 32lbs since November (about 4 months). Down to 169 from 201. I used to hit my drives (and irons) pretty long for 5'8". In the past 4 months I've watched my distance drop. Irons are down approx 10yds across the board and my driver is down 15-20yds.
I'm wondering if it is the weight loss (less mass moving the club) or I've slowed my swing down a bit to be more accurate. I guess it could also be a mental thing where I'm not swinging as hard to conserve energy (due to walking the golf course and knowing I will be tired towards the end of the round).
I'm using premium balls (Prov1, Chromesoft, Kirkland). I've also recently changed to Callaway Steelhead Xr irons (from Callaway Edge Diablo's). The steelheads are supposed to be longer (most of them have less loft than my Edge irons). But, maybe the Edge irons have heavier heads (more mass definitely)?
Lastly, I attended a Callaway Rogue fitting event a couple weeks ago. They monitored my swing speed and it is right around 90. I seem to remember my swing speed 3-4 Years ago was more like 105.
Any specific lifting at the gym I should be doing to bring my speed back up? I assume speed is the main factor here in gaining distance. Or is it mass??
Thanks for any input...
