Sharing a Personal Trainer: Personal and Social Benefits of Individualized Small Group Training.Wayment, Heidi A. Ph.D.; McDonald, Rachel BSJournal of Strength & Conditioning Research: Post Acceptance: March 27, 2017 doi: 10.1519/JSC.0000000000001764 Original Research: PDF Only Abstract We examined a novel personal fitness training program that combines personal training principles in a small group training environment. In a typical training session, exercisers warm-up together but receive individualized training for 50 minutes with 1-5 other adults who range in age, exercise experience, and goals for participation. Study participants were 98 regularly exercising adult members of a fitness studio in the southwestern United States (64 females; 32 males), aged 19-78 years (mean = 46.52 years; SD = 14.15). Average membership time was two years (range: 1-75 months, mean = 23.54 months; SD = 20.10). In collaboration with the program directors, we developed a scale to assess satisfaction with key features of this unique training program. Participants completed an online survey in Fall 2015. Hypotheses were tested with a serial mediator model (Model 6) using the SPSS PROCESS module (14, 30). In support of the basic tenets of Self-Determination Theory, satisfaction with small group individualized training supported basic psychological needs, which in turn were associated with greater autonomous exercise motivation and life satisfaction. Satisfaction with this unique training method was also associated with greater exercise self-efficacy. Autonomous exercise motivation was associated with both exercise self-efficacy and greater self-reported health and energy. Discussion focuses on why exercise programs that foster a sense of social belonging (in addition to motivation and efficacy) may be helpful for successful adherence to an exercise program.
