My favorite form of training is known as High Frequency Training (HFT). High Frequency Training is an advanced form of training which is often used to train multiple fitness qualities. These qualities include maximal strength, speed, cardiovascular endurance, strength endurance, and power. A fallacy that most trainees have is that they think they can just jump into a training program and expect results. In order for a trainee to have long-term success, he or she must identify their individual weaknesses.
