The Best Workout for Teen Fitness Goals Revealed
In today’s fast-paced world, finding effective and engaging fitness solutions for young people is more important than ever. With growing concerns about childhood obesity, cardiovascular health, and mental well-being, schools and after-school programs are increasingly looking for fitness strategies that deliver maximum benefits in minimal time. Among the most promising options is High-Intensity Interval Training (HIIT), a method that combines short bursts of intense exercise with brief rest periods. A recent study comparing HIIT with Sprint Interval Training (SIT) sheds light on how these approaches impact young people’s health and fitness, particularly in terms of body composition, strength, and cardiovascular fitness.
This article will explore the findings of this study, which highlights the unique benefits HIIT offers for adolescents. We’ll see why HIIT could be the ideal choice for school and youth fitness programs, compare its benefits with those of SIT, and provide practical guidance on structuring HIIT workouts that are safe, effective, and enjoyable for young clients. This guide offers insights into how HIIT can help set the next generation on a path toward lifelong fitness and health.
In a recent study, researchers explored the effects of High-Intensity Interval Training (HIIT) and Sprint Interval Training (SIT) on adolescents’ fitness, aiming to see which approach might be more effective in supporting health, strength, and body composition for young people. This study involved sixty adolescents, who were split into three groups: one doing HIIT, another doing SIT, and a control group who continued with their usual Physical Education classes. The HIIT group completed 3 sets of 2-minute work intervals (80-85% of maximum heart rate), while the SIT group performed 6 sets of shorter, higher-intensity sprints (90-95% of maximum heart rate) for 60 seconds each.
After eight weeks, the researchers found that both HIIT and SIT had benefits, but HIIT led the way in several key areas. For instance, adolescents in the HIIT group saw greater improvements in body composition, showing reductions in body fat and trunk fat, alongside increases in lean muscle mass. These gains extended beyond mere aesthetics, impacting their cardiovascular health as well, with lower blood pressure, resting heart rate, and improved VO2 max (a measure of cardiorespiratory endurance). The SIT group, while effective, showed less improvement across these markers, which highlights HIIT’s ability to deliver broader fitness benefits in a relatively short time.
Given its wide-ranging benefits, HIIT offers a time-efficient and effective way to support adolescents in reaching their fitness goals. Importantly, it’s adaptable enough to be used within school or after-school programs, making it accessible for most young people. This research shows that HIIT’s structured intervals—2-minute moderate to high-intensity bouts—allow for significant cardiovascular and strength benefits. For adolescents who may struggle with motivation or the idea of long workouts, HIIT provides a fun, varied approach that keeps engagement high.
In terms of cardiovascular health, HIIT offers a great way to address potential long-term health risks like high blood pressure and poor cardiorespiratory fitness. Additionally, the body composition improvements seen in this study highlight HIIT’s effectiveness for young people who may need to reduce fat mass, a key factor in reducing early risk factors for obesity and metabolic health issues.
Objective: Familiarise young clients with the HIIT concept and build a solid foundation in movement and technique.
Workout Example:
Objective: Increase the duration of the working phase and introduce strength-focused intervals.
Workout Example:
Objective: Introduce sprint intervals to build anaerobic power and endurance.
Workout Example:
Objective: Lower intensity slightly to allow recovery and consolidation of gains.
Workout Example:
This study highlights HIIT’s broad-ranging benefits for youth, from cardiovascular health to strength and body composition. Its structure is easy to adapt, and with careful periodisation, HIIT can provide a fun, challenging, and effective training programme for adolescents. Fitness professionals can make use of these findings to build safe, engaging HIIT sessions that help young people develop a positive relationship with fitness and health.
