How does the first session with Manager Jeong Ui-seong begin?

At PAFGYM, the first three sessions focus on consultation and assessment rather than jumping straight into exercise. We check your body composition with InBody, review your movement through basic exercises, and look at your endurance to set your starting point together. Based on the movement check, Manager Jeong Ui-seong decides the order in which you will learn kettlebell and barbell movements, and if you have a race goal, he builds a preparation plan around that schedule.
