Pick a swing (short, long, mid) and practice it anyway you want – 100 times a day for a month. I heard Steve Stricker abides by simple routines like these to keep himself golf-focused during his hometown long winter months.
nothing fancy. you can try it like an air guitar or with a club-in-hand but with no ball or with an actual club and ball into a practice net in the back yard or out on the range ….- whatever….. Just swing away 100 times everyday like you’re taking practice jump shots in basketball or something and that’s it. walk away. remember to warm up lightly before and after. i find that we guys forget to warm up and down (especially stretching the shoulders) and that causes unnecessary muscle injury because we think we’re still 20-somethings.
Just do that for a month and your swing and groove and mental memory will improve. Sometimes the simple things make a big difference if we keep at them persistently. Now that a mystery but it’s true. Life lesson and a golf training tip. Ch-ching.
