Like suntans and the ability to throw knives at apples on top of totem poles, golf skills disappear if you don't keep working at them. Keep the magic alive with today's Groupon: for $28, you get a 30-minute private golf lesson at The Golf Den in Sherwood Park (a $59 value).

The Golf Den's knowledgeable instructors helm indoor virtual golfing lessons that help players of all abilities ameliorate their clubbing prowess through simply presented custom lesson plans. Each 30-minute private lesson employs V1 Pro video analysis software and three flattering camera angles to conduct a fundamental swing evaluation, allowing instructors to diagnose problem areas and applaud emotive close-ups as they review the resulting moving picture. Putting pedagogues then lead students through drills designed to address individual form and teach techniques centered upon enhancing score-lowering skills such as grip, club rotation, kinetic linking, and spin control. Virtual assessment technologies and instructor-gleaned savvy combine to give golfers access to a level of personal analysis hard to find outside of one-on-one encounters with fairway-dwelling Freuds. Once lessons have finished and tearful farewells have been bidden, students receive a copy of their swing video in their email inbox for screening during living-room film festivals, along with a lesson summary for future reference.

The Golf Den advises pupils to bring along their own clubs, clean golf or tennis shoes, and life-size cutouts of Arnold Palmer to their lessons. Rental clubs are available for an additional $10 fee (not included with today’s deal). The Golf Den is open seven days a week during the winter, allowing golfing gurus to keep their game sharp throughout the off-season. Peruse the online FAQs for more information.
