I just finished 2months of training and took 1 week off last week. My green shaft is up to low 120mph now, but i started to have some pain on my outer left knee towards lower left between my calf and the knee, possibly IT band. Has anyone feel this type of pain during the training?
I get a little ankle and knee aches after swinging in my garage setup some times. There is no amount of stretching unfortunately that stops for me. I do not get this issue out on the course or range so I attribute it entirely to the turf I am swinging on. It doesn't allow my foot to turn so easily and I roll my ankle that much harder. When you swing all out, it puts a LOT of stress on your ligaments, just like a major league pitcher's arm. You have to be careful and stop when you feel any aches. Let yourself recover. I also think how much you feel this depends on your age and how stretchy your ligaments still are.
I myself try to only swing with my morning slippers on, it allows my leg to turn out better so its less hard on it. Forearms can really take abuse too depending on your grip style, and how fast you a able to physically move that club. Someone moving a stick at 140 vs someone moving it at 110 is probably going to feel significantly more stress on their body. I have a super strong grip, tend to get very inside out when I swing really hard and therefore my forearm really wrenches over at the last second. Very hard on it when you swing, especially with the heavy stick.
