9. Group personal training: This trend makes personal training possible for many who could otherwise not afford it. This builds in a support group and is a win/win for both trainer and client.
10. Yoga: Because of the many forms and intensities of this ancient practice, it is re-emerging. Yoga has mastered the art of repurposing itself. Certifications are growing, and older adults are figuring out that because of the many gentler forms, yoga is yet another age-appropriate choice for them.
11. Exercise for childhood obesity: Another surprise drop, since we seem to just now be getting the message that this is a major health issue and precursor to Type II diabetes. If spun correctly and collaboration enters the picture, this might just move back up into top 10.
12. Worksite health promotion: It's important to note that this one is on its way up, not down.
13. Core training: Spent three years in the top 5 then began the slide to 13. Still, it's important and keeps reinventing itself with new toys -- balls, boards and such.
14. Outdoor activities: Slowly on its way up as trainers step out of the fitness centers to discover physical adventure. More fun, less boredom and burnout on the part of trainer and client.
15. Circuit training: Similar to HIIT but less intense. A series of 6 to 10 exercises in a sequence that alternates work/recover efforts.
16. Outcome measurements: Reappeared at No. 17 in 2013 and moving up, outcome measurements is all about accountability. It is critical to employers who decide whether to fund physical activity and health promotion because it proves whether or not an activity/program works.
17. Wellness coaching: Hanging on but falling, wellness coaching connects behavioral change science to health promotion and disease prevention, which more personal trainers are adopting.
18. Sport-specific training: Designed to enhance sports skills for young athletes, it has bounced around the top 20 like a racquetball. Don't count it out.
19. Worker incentive programs: Represents a resurgence of corporate health promotion programs as a result of rising health-care costs experienced by companies. Aims to stimulate positive healthy behavior change.
20. Boot camp: Losing ground, this high-intensity structured class includes cardiovascular, strength, endurance and flexibility drills and calisthenics. Because of its rise and fall since 2008, it will be interesting to see if it can hang on or be forced to evolve.
Fad to flop
Keep in mind that just because something makes the trends survey doesn't necessarily define it as a trend. It may make an appearance for a year or two and then drop out of sight, returning to fad status. Most of us remember but don't use toning shoes, shaker weights and the Ab Roller, which is why these surveys make sense to both fitness and business industries.
Investors making decisions on fitness products and programming should steer clear of late-night infomercials with celebrity endorsements and look to those which are strong enough to hold a spot on the top 20 trend list.
