Tighten your game: keep mid irons within 6 yards

Pick one flag/target suitable for mid irons (7, 6, or 5 iron).

Hit 36 shots in total at that single target.

Hit half the shots curving left-to-right and half curving right-to-left. Use different irons if you want.

Stand the same way for every shot. Only try to change the way the ball curves.

If a shot lands close to the target (within a range you decide), count it as a success.

When finished, count how many good shots you got out of 36 and enter your score in the app.

Set up 5 cones 10 yards apart on the driving range.

Mark 3 corridors, each 8 yards wide, between the cones.

Hit 35 iron shots in total.

Split the shots into 5 groups of 7, aiming at each cone in turn.

Try to land each shot inside the 8-yard corridor by the target cone.

Count each shot that lands in the right corridor and distance as a success.

When finished, count your successful shots out of 35 and enter score in the app.

Pick a 5, 6, or 7 iron for the drill.

Choose a flag or mark at a medium distance.

Make a square around the target using four markers, each marker about 5% of the distance to the flag away from it.

Hit 36 shots, divided into 4 groups of 9 shots each.

For each group, aim to land the ball in one specific quadrant.

Start with one quadrant and hit 9 shots, then do the same for each of the other 3 quadrants.

Switch between the 5, 6, or 7 iron any time.

Count each ball that lands and stops in the target quadrant as successful.

Add up your total successful shots and enter your score out of 36 in the app.
