design and develop a fitness training routine (bootcamp, gym circuit, aerobics, etc.) that you could teach in order to achieve a specific goal (i.e. speed, agility, power, balance, coordination, muscular endurance, cardiovascular fitness, etc.). Note however, that many fitness routines/workouts focus on more than one area and could be designed to elevate your heart rate and/or develop a specific skill such as agility, speed, or power.
