*
for ANOVA. Annual exercise frequency = sessions performed/sessions prescribed for that year. These annual exercise frequencies were then averaged over the 6 years. Weight lifted in military press and squats represents annual kilograms multiplied by repetitions and by sets and then summed for 6 years.
