When developing an exercise program, the Group Fitness Instructor (GFI) should add or change one element at a time to make sure that all class participants remain on the learning curve. The acronym DRILL can help the GFI recall which elements to change or add. What does LL in DRILL stand for?
Explanation
Answer: D - The acronym DRILL stands for direction, rhythm, intensity, and lever length. By changing the lever length, instructors can make the workout more difficult as the lever increases. An example of elongating the lever to gain resistance is the use of a resistance bell or paddle when exercising in the water. The resistance device elongates the length of the limb, plus increases the frontal surface area. These effects, combined with a decrease in streamlining, increase the work-out load.
