The Honest Truth About “Free”
If you're a new trainer trying to keep costs down, searching for free software makes total sense. You're already paying for a certification, insurance, maybe gym rent or equipment. Why add a $100/month software subscription before you've signed your tenth client?
The problem is that "free" in the software world almost always comes with a catch. Sometimes the catch is a client cap that makes the platform useless once you grow. Sometimes it's missing features that force you to cobble together three different tools. Sometimes, and this is the sneakiest one, the catch is your time. A platform that costs $0/month but eats 10 extra hours of manual work per week is the most expensive software you'll ever use.
Here's a genuinely honest breakdown of what's available in 2026, what each option actually includes, and when it makes sense to pay for something better.
The Spreadsheet Route: Google Sheets & Excel
Cost: $0. Client cap: None. Catch: Everything else.
Every trainer has done this at some point. A shared Google Sheet with exercise names, sets, reps, and maybe some conditional formatting. It works. Your clients can access it from their phone. You can duplicate tabs for new weeks.
The problems compound quickly. There's no exercise video library, your clients see text names and have to Google the movements. There's no progress tracking beyond what you manually type. There's no way to collect payments, schedule sessions, or send automated check-ins. Your client sees a spreadsheet and thinks: "Am I really paying $200/month for this?"
Spreadsheets are fine for your first 2–3 clients while you figure out what you actually need from a platform. Beyond that, the unprofessional look costs you clients who compare your experience to competitors using real software.
Free Tier Platforms: What You Actually Get
Several platforms offer free plans or free trials. Here's what each one includes at no cost, and where the walls go up:
My PT Hub, Free for up to 5 clients
My PT Hub has the most generous permanent free tier. You get basic workout creation, client profiles, and a nutrition tracker for up to 5 clients. The interface is functional but dated. The exercise library is decent. No AI, no custom branding, no payment processing on the free plan. Paid plans run $40–80/month once you outgrow the cap.
TrueCoach, 14-day free trial
TrueCoach doesn't have a permanent free tier. You get 14 days to try the full platform, then you choose between $19/month (up to 5 clients), $49/month (up to 30), or $99/month (unlimited). TrueCoach's strength is its clean workout delivery and client communication. The limitation: no AI workout generation, no financial tools, and the per-client pricing model gets expensive fast as you grow.
Harley AI, 14-day free trial, then $49.99/month Pro
Harley AI offers a 14-day free trial on paid plans, plus a permanent Starter tier (up to 5 clients, no charge). The Pro plan at $49.99/month includes unlimited AI workout generation, Stripe payment processing with 0% platform fees, wearable integrations (Whoop, Apple Health, Health Connect), and Artha , an AI financial advisor that tracks your revenue and flags churn risk. One-click migration from Trainerize, TrueCoach, or Everfit is included.
Trainerize, 30-day free trial
Trainerize offers a 30-day trial, but the base plan is limited. To get payments, nutrition tracking, video libraries, and business tools, you're adding $10–50/month in add-ons. Most trainers end up paying $150–250/month for the full feature set. The platform is established and widely used, but the add-on pricing model means the sticker price is misleading.
Everfit, Free trial, then $79–159/month
Everfit's free trial gives you access to their full platform for a limited time. Plans start at $79/month for up to 25 clients. The workout builder is solid and the client app is well-designed. No AI workout generation. Payment processing is available but incurs platform fees on some plans.
What Free Plans Don’t Include
Across every platform, free plans share the same gaps:
- AI workout generation: Not available on any free tier. You're writing every program manually.
- Custom branding: Your clients see the platform's logo, not yours.
- Payment processing: You're invoicing separately through Venmo, Zelle, or Square.
- Wearable integrations: No Whoop, Apple Health, or Garmin data flowing into programming decisions.
- Financial tools: No revenue tracking, no churn prediction, no business intelligence.
- Client limits: Usually capped at 5 clients, which means you outgrow the free plan within your first month of serious business.
The free tier exists to get you in the door. That's not cynical, it's just how software works. The question is whether the paid version delivers enough value to justify the cost.
The Real Cost of “Free”
Here's the math most trainers don't do. If you're spending 30 minutes per client per week on manual programming, scheduling, and invoicing, work that good software automates, and you have 15 clients, that's 7.5 hours per week of unpaid administrative work.
If your effective hourly rate is $60 (after expenses), those 7.5 hours cost you $450/week in opportunity cost, time you could spend training more clients, creating content, or simply not working on Sunday night. That's $1,800/month in lost productive time to save $50–100/month on software.
There's also the client experience factor. Trainers using professional platforms with branded apps, exercise video libraries, and integrated payments have measurably better client retention. A client who receives a polished workout with video demos on a clean mobile interface feels the premium they're paying for. A client who gets a Google Sheets link does not.
When to Upgrade
The break-even point is surprisingly low. If you have 5 or more paying clients, the time savings from proper software almost certainly exceed the subscription cost. Here's a simple test:
- Are you spending more than 1 hour/week on manual programming that software could automate?
- Are you invoicing clients through a separate app (Venmo, Zelle, Square)?
- Have you ever had a client comment on the look or feel of how they receive workouts?
- Are you copy-pasting programs across clients because you don't have time to individualize?
If you answered yes to two or more, you're already paying for software, just paying with your time instead of money. The upgrade isn't an expense. It's a recovery of hours you're currently losing.
Best Value in 2026
If you're going to pay for a platform, the question becomes which one gives you the most for the money. At $49.99/month, Harley AI includes features that cost $150–250/month on legacy platforms: AI workout generation, Stripe payments with 0% platform fees, wearable integrations, and an AI financial advisor (Artha) that tracks your revenue and business health in real time.
The AI component matters more than it might seem. A trainer with 25 clients who spends 30 minutes per program manually is spending 12+ hours per week on programming alone. AI generation reduces that to under 2 hours. That's not a marginal improvement, it's the difference between a sustainable business and burnout.
If you're just starting out with 1–3 clients, use the free options. Google Sheets, My PT Hub's free tier, or Harley's Starter plan will get you through the first few months. But the moment you cross 5 clients and start feeling the time pressure, invest in the tool that gives you hours back. Your clients will notice the quality difference. Your bank account will notice the revenue you can capture with the extra time.
