Unlike other weighted trainers, this club eliminates the boredom involved in developing and strengthening the golf muscles because you can actually take it out on the range to hit balls, receiving immediate feedback. Or you can just using it at home or at the office. The Heavy Hitter iron goes above and beyond other weighted clubs. A practice swing may seem flawless, but it's the swing taken at the ball that counts. The weighted 7-iron is 740 grams (26.4 oz) and is available right-handed only with or without preformed training grip.
