Fitness coaches in fitness clubs are divided into group gymnastics coaches and personal trainers. Personal fitness trainer refers to a professional fitness trainer who conducts one-on-one training in a fitness club. Their work is interactive and targeted, and they are charged according to class hours. There are one-to-many group gymnastics coaches, and one person leads most members to do aerobic exercise in the aerobics hall (group gymnastics courses include aerobics, aerobic dance, pedal, rotation, fighting, Pilates, yoga, etc.). ).
