Hapkido is predominantly a "soft" art, but this does not mean that it is easier on the opponent, or that training is easier (see Hard and soft (martial arts)). Hapkido training is vigorous and demanding. The practitioner could benefit in training by being lean and muscular. However, strength is not a prerequisite of hapkido; what strength and fitness is necessary to perform the techniques develops naturally as a result of training.
