Quick Facts: Personal Training Side Hustle
What You'll Do as a Personal Trainer
Personal training is one of the most rewarding side hustles available because you get paid to help people transform their lives. You'll design individualized workout programs, coach clients through sessions, track their progress, and adjust their training based on results. Every client is different - some want fat loss, others strength, and some just want accountability.
The most successful side hustle trainers combine in-person training with online coaching through platforms like Trainerize. In-person clients pay $60-$100/session, while online clients pay $150-$300/month for programming and check-ins you can manage in the evenings. A trainer with 8 in-person clients and 10 online clients can earn $4,000-$6,000/month part-time.
Client retention is where the real money is made. A client who trains with you for 2 years is worth 20x a one-session client. Your energy, personality, and ability to keep clients motivated and seeing results is what drives long-term income.

How to Get Started: 7 Steps
-
Get NASM or ACE certifiedEarn a nationally recognized personal training certification. NASM (National Academy of Sports Medicine) is the most respected in the industry and costs $400-$800. ACE (American Council on Exercise) is a strong alternative. Both require passing a proctored exam that you can take at a testing center. Study time: 3-6 months depending on your pace.
-
Get CPR/AED certifiedCPR/AED certification is required by NASM, ACE, and virtually every gym before you can train clients. It costs $30-$50 and takes a 4-6 hour in-person class. The American Heart Association and Red Cross both offer regular courses in most cities.
-
Get personal trainer liability insuranceLiability insurance ($150-$300/year) protects you if a client is injured during a session. NASM and ACE both offer member insurance through partnerships. Having coverage is typically required to train at commercial gyms and gives clients confidence in your professionalism.
-
Build your fitness presence on InstagramPost 3-4 times per week sharing workout tips, technique breakdowns, and your own training journey. Instagram is the single most effective organic marketing tool for personal trainers. Before/after client posts (with permission) and educational content are the highest-performing formats. Consistency over 90 days compounds into real client inquiries.
-
List on Thumbtack and approach local gymsCreate a professional Thumbtack profile to generate early leads. Simultaneously, visit local gyms and fitness studios to ask about renting floor space by the hour or getting on their independent trainer referral list. Many gyms are open to this arrangement and can send you overflow clients.
-
Offer a free assessment session to your first prospectsOffer a complimentary fitness assessment and goal-setting session to your first 5-10 prospects. This eliminates price objections, demonstrates your expertise, and gives you the opportunity to show your personality before asking for a commitment. Most well-conducted assessments convert at 60-70%.
-
Sell packages and launch online coachingSell 4 or 12 session packages instead of single sessions to improve retention and cash flow. Once you have 5+ in-person clients, set up Trainerize and launch an online coaching offer at $150-$300/month. Each online client adds recurring monthly revenue for just 1-2 hours of weekly work per client.

Frequently Asked Questions
What certification do I need to become a personal trainer?
The most recognized certifications are NASM (National Academy of Sports Medicine) and ACE (American Council on Exercise). Both require passing a proctored exam and cost $400-$800. ISSA and NCSF are also well-regarded and accepted at most gyms. NASM is generally considered the industry gold standard and commands the highest client trust, especially for trainers working in commercial gyms.
How much can a personal trainer earn on the side?
Part-time personal trainers typically earn $40-$60/hr starting out. With experience and a full client roster, intermediate trainers earn $60-$80/hr. Trainers who combine in-person clients with online coaching can achieve $80-$100+/hr equivalent. Working 10-15 hours/week, most trainers earn $1,500-$3,500/month part-time within their first year.
Can I train clients without access to a gym?
Yes - many trainers work outdoors at parks, at clients' homes, or rent gym floor space by the hour. A basic kit of resistance bands, adjustable dumbbells, and a TRX suspension trainer lets you deliver effective full-body sessions anywhere. Park training works especially well for cardio, bodyweight, and outdoor-oriented clients. No gym access needed to start.
How do I find my first personal training clients?
Start with people you know - friends, family, and coworkers who want to improve their fitness. Offer a free first assessment session and ask for a referral if they enjoy it. Build a consistent Instagram presence posting workout tips and your own fitness content. List on Thumbtack and Gympass/Wellhub. Ask local gyms about getting on their independent trainer referral list. Most new trainers land their first 3-5 clients through personal network alone.
Is online personal training worth it as a side income stream?
Online training has exceptional ROI for side hustle trainers. Once you build your systems (custom programs via Trainerize, weekly check-in messages, progress tracking), you can serve 10-20 online clients with just 2-3 hours of additional weekly work. Online clients typically pay $150-$300/month, so 10 clients adds $1,500-$3,000/month with minimal time investment relative to in-person training.
