Take one step back to take two steps forward with your skiing. This is the time to start working on back-to-backs (skiing two passes through the slalom course or open water without stopping or resting). Drop down a few line lengths or decrease the speed until you can run six to eight passes in a row. This exercise really helps you build strength and consistency but may be impractical in the summer when a tournament's right around the corner. Start off easy with only one to two back-to-backs and build up from there. Set goals for the number of back-to-backs you can complete and write the results down in a journal.
Select one aspect of your skiing which has troubled you and work exclusively on trying to improve it for one to two weeks, then choose another trouble area and do the same. Isolating the trouble spots will help you maintain your focus. Don't fall into the trap of trying to fix everything at the same time. Concentrate on one thing such as the gates, your pulling position, edge change, reach, pre-turn and turn. If you improve these individual aspects, you will be amazed at the difference when you put everything back together as you get closer to summer time. Tournament skiers usually don't have this luxury of time during the season, since more emphasis is placed on the number of buoys scored rather than technique. Remember, take one step back to take two forward.
