How It Boosts Your Income 

The market for pre and postnatal fitness may seem niche, but it’s anything but small. Each year, millions of babies are born (3.6 million babies were born in 2024 in the United States alone, according to CDC data). That’s millions of new and expecting parents, parents who need support and guidance to stay healthy and active during pregnancy and recover with confidence after birth. 

Offering prenatal and postnatal fitness services can be both personally rewarding and financially sustainable. A well-structured postnatal fitness program can generate an estimated $50,000 to $150,000 in annual revenue, depending on your model, pricing, and reach. 

Stepping into this specialized field not only expands your income opportunities, but it also positions you as a trusted expert for a uniquely motivated and loyal population. You’re not just helping someone build strength or hit a goal; you’re supporting people through one of the most significant transitions of their lives. That kind of work doesn’t just build a career. It builds legacy and trust, qualities that will open doors for years to come. 

Kettlebell Essentials: The Iron Cardio Approach Certificate 

Kettlebells are no longer a fringe tool in the gym—they’re a cornerstone of functional strength and endurance training. AFPA’s Kettlebell Essentials course, led by renowned coach Brett Jones, introduces the Iron Cardio method: a fluid, endurance-based system that combines kettlebell strength and cardiovascular conditioning. 

This specialty certificate includes: 

• Six video-based modules teaching core lifts: Clean, Press, Squat, Snatch 
• Structured progressions using the Iron Cardio protocol 
• Real-world programming samples 
• Hands-on technique instruction 

Whether you’re a beginner or an experienced trainer, this course helps you build safe, effective kettlebell workouts that challenge the body without maxing out intensity. The Iron Cardio method emphasizes sustainability and flow—perfect for clients who want to build strength and conditioning without burnout. 

How It Boosts Your Income

Kettlebell training attracts a wide audience, from busy professionals to athletes. With this specialty certificate under your belt, you can offer dynamic one-on-one sessions to help your clients get stronger, burn calories, and become more athletic. This is a high-value skillset that appeals to functional fitness fans, hybrid training enthusiasts, and anyone looking for a break from more traditional workouts. 

In 2023, the kettlebell global industry was valued at $51 billion, and it’s projected to grow to $116.2 billion by 2031, rising at a compound annual growth rate (CAGR) of 9.1%. North America alone holds about 40% of that market, with strong growth expected over the next decade. 

What does that mean for instructors? It means more clients are buying kettlebells, signing up for classes, and searching online for kettlebell programming. As demand grows, so does your opportunity to charge premium rates for this specialized, effective type of training. 

You can teach group classes in commercial gyms or studios, run virtual kettlebell bootcamps from anywhere, or create digital programs and instructional content. The expanding audience translates into greater income potential and flexibility for your career. 

Pilates Instructor Certification 

If you want to expand into low-impact training that delivers major results, Pilates is a powerful path forward. AFPA’s Pilates Fitness Instructor Certification is an accessible, fully online program that prepares you to teach Pilates mat classes with confidence. 

Inside the course, you’ll learn: 

• Foundational Pilates mat exercises and progressions 
• Anatomy, movement principles, and injury considerations 
• How to teach multi-level classes and provide modifications 
• Routines for special populations, including clients with lower back pain 

With over 300 photo-supported exercises, downloadable routines, and three digital textbooks, this course equips you to deliver safe, engaging Pilates experiences in-person or online. 

How It Boosts Your Income 

Demand for certified Pilates instructors is booming. According to a 2024 global survey of 800 instructors conducted by Balanced Body®, 77% of Pilates studios report active growth, and 67% say their classes are selling out. Studio owners are struggling to keep up with demand: nearly 40% say they need more instructors, and 30% are actively hiring. 

Instructor numbers are rising, but not fast enough to fill the gap. Since 2015, the number of new instructors entering the field has grown by 15%. Yet demand continues to outpace supply, creating strong job prospects for newly certified professionals. Also worth noting, the survey showed that career satisfaction among Pilates instructors is high. 92% of instructors would recommend becoming a Pilates instructor to others, 89% say they love their job, and 79% look forward to going to work every day. 

From big box gyms to boutique studios to private virtual sessions, clients are seeking expert Pilates instruction. Adding this credential will allow you to reach new demographics, offer specialized services that complement your personal training, and ultimately, increase your earning potential. 

Certified Health and Wellness Coach Program 

What if you could help clients achieve transformation beyond the gym? With AFPA’s Health and Wellness Coach Certification, you’ll be equipped to support long-term lifestyle change by addressing physical, emotional, and behavioral factors. 

This program goes far beyond fitness. It’s a complete, board-eligible training in holistic coaching. You’ll learn: 

• Motivational interviewing and behavior change science 
• Holistic health strategies including stress management, nutrition, and movement 
• Legal and ethical considerations for coaching 
• Client communication and business development 

Featuring over 35 hours of video content, simulated coaching sessions, and downloadable handouts, this certification empowers you to help clients navigate complex wellness challenges, whether it’s eating habits, work-life balance, or mental well-being. 

How It Boosts Your Income 

Health and wellness coaching is a powerful add-on service to personal training. For example, with this certification you could expand from weekly workouts to more holistic monthly wellness coaching packages. This course allows you to offer clients more comprehensive support and unlock recurring revenue streams. Plus, it opens doors to working with clients remotely, one-on-one, or in group coaching formats. 

And the income opportunity is significant: in the U.S., the average health coach hourly rates often range from $20 to $30, and private practice providers charge even more. Those who specialize or build strong digital programs frequently earn into the six figures. With a solid certification and coaching package in place, you’re well-positioned to tap into a growing market, projected to reach $7.8 billion in U.S. health coaching revenue by 2028. 

Yoga Instructor Certification 

Yoga’s reach keeps expanding: roughly 10% of Americans say they practice yoga, and the global yoga market is projected to top $66 billion by 2027. That momentum means opportunity for fitness pros who can weave mindful movement into their service menu. AFPA’s Yoga Instructor Certification gives you a practical, tradition-honoring pathway to join (or lead) the flow. 

Designed by expert educator and yoga professional Rena Shoshana Forester, this 100% online, self-paced course provides the knowledge, confidence, and practical tools needed to lead safe, meaningful classes for students of all levels. Unlike more rigid, time-intensive yoga programs, this certification was created to be flexible and more cost-effective.  

This course covers: 

• Yoga philosophy & fundamentals (Eight Limbs, Chakras, Pranayama) presented in clear, modern language 
• Essential asana breakdowns with sequencing tips you can plug straight into classes or one-on-one sessions 
• Ready-to-teach resources: downloadable lesson plans, meditation scripts, and three full-length practice videos (90-, 45-, and 30-minute formats) 
• Flexible, self-paced learning across 19 bite-size modules you can complete in six months or less, entirely online 

How It Boosts Your Income

Yoga instruction is a versatile service that you can offer in countless settings: gyms, studios, corporate offices, retreats, wellness platforms, or even from your own home.
