Vigo was busy dealing with the Crow Gang's affairs, so Jimmy was quite relaxed. The case wasn't his; he was just a junior trainee agent still in the learning phase. After work, his time was entirely his own. Having not exercised in a while, Jimmy found a gym close to his apartment to work out.
Exercising had become a habit for Jimmy. Back in Little Rock, he would go to the gym at least 2-3 times a week. At the FBI Academy, there were dedicated coaches to monitor and plan workout routines to ensure that trainees were in peak physical condition. Although he had left the academy, he still remembered some of the training.
Jimmy was mostly in the office now, and he drove when he went out, which significantly reduced his physical activity. However, he didn't cut back on his eating, and although it had only been three weeks, he could already feel that he was gaining weight. Exercising after work was the best way to burn off energy.
