Despite public health efforts¹, only ~2 out of 10 Canadian adults meet the recommended minimum of 150 minutes of moderate to vigorous physical activity per week.² Furthermore, those of us that do take the initiative to hit the weight room may find that sticking to our plans is more difficult than anticipated. It may be relieving to know, however, that this is a common experience among new gym-goers, about 50% of whom either cease exercising altogether or report decreased physical activity levels within the first months following exercise initiation.³⁻⁴ This may be mediated in part by the amount of pleasure derived from exercising.⁵ This week's article will therefore discuss how to manipulate your strength training variables to promote exercise enjoyment, and thus, lifelong exercise adherence.
High intensity exercise generates feelings of displeasure.⁶ Therefore, start out by performing 2 workouts per week.⁷ On a Rating of Perceived Exertion (RPE) scale of 1-10 (1 and 10 being minimal and maximal subjective effort respectively), you should aim for an RPE of 5-8.⁷ Perform 2-3 sets per muscle group.⁷ Prioritize exercise machines as opposed to free weights since they are safer and do not require advanced neuromuscular control.⁷⁻⁸ More specifically, opt for machines that target small muscle groups such as the leg extension machine as opposed to large muscle groups like the leg press.⁷ Rest for about 90 to 150 seconds between sets.⁷ Shorter rest periods may produce anxiety and longer rest periods may produce boredom.⁹ Perform your favorite exercise last to conclude workouts on a positive note.¹⁰
After some time, this training protocol will become too easy. At this point, you can add an extra training session into your week.⁷ Perform 3-4 sets per muscle group at an RPE of 6-10.⁷ You can also experiment with different exercises to see what you enjoy the most.⁷ At this stage, you should be familiar with your bodily responses to exercise and can self-select rest times between sets.⁷ Once again, perform your favorite exercise last to conclude workouts on a positive note.⁷
Although this information may be overwhelming at first glance, it can be comprehensively summarized in the following statement-start out slow and focus on making sustainable progress over time! Good luck!
