Long-Term Athletic Development (LTAD) models have provided a youth sport framework for more than 2 decades, aimed at improving skill progression, training outcomes, and athlete preparation. Although influential, traditional LTAD approaches are limited by their sport-centric orientation, linear design, and focus on elite performance, leaving them less relevant for most youth and adults who do not pursue competitive sport. In response, we propose reframing LTAD as Long-Term Activity Development (LTActD), an accessible and flexible model designed to promote lifelong engagement in physical activity, including recreation, exercise, and sport. LTActD emphasizes 5 dynamic phases—Explore, Develop, Apply, Sustain, and Thrive—that accommodate diverse pathways, periods of inactivity, and opportunities to re-enter active living at any age. Represented as a curvy road, the new model underscores that participation in physical activity is rarely linear, more like a winding journey shaped by health, motivation, environment, and social context. LTActD bridges sport science and public health, positioning physical activity as a lifelong resource for health, independence, and fulfillment. LTActD offers a practical framework to empower individuals of all ages and abilities to discover meaningful ways to move, re-engage, and embrace active living throughout the life course.

A common obstacle to achieving recommended physical activity and desired training goals is time. This is true for recreationally trained adults and athletes, particularly at the collegiate level, where greater restrictions on practice time and training are in place. One possible solution is to implement time-saving and time efficient training routines and methods that may limit the amount of time needed to attain desired physiological adaptations—by decreasing the time needed to train and/or by increasing the frequency with which brief workouts are completed throughout the week (e.g., “microdosing”). To provide the most optimal training stimulus, the correct method must be used. Unfortunately, numerous terms describe routines and methods discussed in the current body of available literature, many of which may seem similar and lead to confusion. The purpose of this article is to outline the similarities and differences of the numerous timesaving and time-efficient training routines and methods. Ultimately, this article synthesizes the current research into practical recommendations as programming options for strength and conditioning coaches and personal trainers. The information provided may also serve as a foundation for future research opportunities in time-saving and time-efficient training.
