  • Values are means (SD). There were no significant baseline differences between groups.

  • a Rx amount (72 sets/wk) = 3 days/wk, three sets of 8–12 reps, on eight different machines.

  • b Actual amount (sets/wk) = Rx amount × adherence.

  • c Rx amount (14 kcal.kg−1.week−1) is approximately calorically equivalent to 12 miles of jogging per week.

  • d Actual time (min/wk) = Rx time × adherence.
