Enjoyable gym activities are crucial for mental health benefits, and various forms of exercise have similar effects on mental health. Strength training benefits are seen in adolescents and older adults, and resistance training reduces depressive symptoms regardless of strength gains.

  • How can exercise help in managing mental health disorders?

    Exercise is beneficial for preventing, managing, and improving mental health disorders. It can reduce depressive symptoms, improve sleep quality, and boost mood, even with occasional breaks. The mental health benefits of exercise may have a longer-lasting systemic impact rather than just a temporary boost. Combining cardio and resistance training may provide the most benefits for mental health, and coaches should encourage exercise while also opening a dialogue about potential mental health issues. Strategies to enhance adherence to exercise protocols are crucial for coaches to support clients' mental health.

  • What should coaches prioritize for clients' mental well-being?

    Starting with low exercise intensity, like 4-6 sets per muscle group, can be beneficial in balancing training efforts to avoid exhaustion. Progress in the gym can be seen with just half an hour to a couple of hours per week, and tracking post-workout feelings and energy levels can help gauge training effectiveness. Reflecting on gym time and its impact on overall life balance is crucial for mental well-being, as overtraining in the gym can lead to neglecting other aspects of life.
