This might be a very dumb question… I’ll hit 200-250 balls every other night. I’m working on my swing myself. I do the speed training in the spring and summer. I am 63 years old, I would also say a young 63. I’m not a physical specimen, (I used to be) I’m 6’ 250/255. That’s up 25/30# from my college playing weight as a Strong Safety. So like your Pre-Shot routine, what is your Pre-Workout routine??? Do you have one? If you are coming out overly sore, you are doing something wrong! I take 800mg of Ibuprofen, I then start stretching, hammies, back, hips, shoulders, neck, tri’s. The stretch takes a good 20 minutes. After that, I also start slow, with my belt buckle drill, sometimes with a ball, sometimes without a ball. When, I’m done the session, I do a 5 minute cool down, static stretch. When you are speed training, you are releasing so much lactic acid into your system and really increased circulation. Especially, as you get older, understand what you are doing. Speed training is weight training. You are doing something unnatural. In the summer, I walk the course, I stretch! The Mechanic simple stretch Miguel is the best, imagine, what he’s doing before he plays. OLder players really need to work on flexibility, decent nutrition, lots of H2O. You can mess yourself up good, if you don’t. If you are a 6pack cart golfer…sorry I got nothing for you…LOL! If you really want to take it to another level, try some yoga stretches. I hate to tell you, but when we played ball in college, it was mandatory for us to sign up for ballet stretches, not a joke. Take your workout seriously. Just don’t go to whacking balls! Hope that helped!
