Is F45 HSA Eligible?

Yes, F45 Training memberships can be HSA eligible when you have a Letter of Medical Necessity (LMN). F45's functional group training format — with structured, coach-led sessions — makes it a strong candidate for HSA and FSA coverage. With F45 memberships ranging from $50-$70 per week ($200-$280/month), using pre-tax dollars can save you $850-$1,250 per year.

What Makes F45 a Good Fit for HSA Eligibility

F45 Training stands out from generic gym memberships in ways that actually strengthen your HSA eligibility case. The "F" stands for functional — meaning the workouts are designed around movements that improve everyday physical capacity. From an HSA perspective, this matters because:

Coach-led sessions. Every F45 class is supervised by trained coaches, making it more analogous to a prescribed exercise program than unsupervised gym time. Structured programming. F45 follows a set weekly schedule (cardio days, resistance days, hybrid days) designed by exercise physiologists. This systematic approach aligns with how medical professionals would prescribe an exercise regimen. Heart-rate monitoring. F45's Lionheart system tracks your heart rate throughout each class, providing measurable data that connects directly to cardiovascular health outcomes.

How to Make F45 HSA Eligible

The process is straightforward:

Have a qualifying medical condition. This includes obesity, cardiovascular disease, type 2 diabetes, hypertension, depression, anxiety, metabolic syndrome, chronic pain, or any condition where a doctor would prescribe exercise.

Get an LMN from a licensed provider. The letter should state that structured exercise like F45 Training is medically necessary for treating your specific condition.

Keep your F45 receipts. Monthly membership statements, payment confirmations, or credit card records.

Submit for HSA/FSA reimbursement. File a claim with your administrator along with your LMN and receipts.

That's it. Once you have your LMN on file, each month's F45 payment becomes an HSA-eligible expense.

F45 HSA Savings Breakdown

F45 is a premium fitness investment, so the HSA tax savings are meaningful:

• F45 membership at $240/month: $2,880/year
• Tax savings at 30% combined rate: ~$864/year
• Tax savings at 40% combined rate: ~$1,152/year

For higher earners in states with income tax, the savings can approach or exceed $1,200/year — that's essentially 5 months of F45 training paid for by tax savings alone.

F45 Challenge Programs and HSA Eligibility

F45 is known for its periodic 8-week Challenge programs, which include nutritional guidance, InBody scans, and structured fitness goals. These challenge fees may also be HSA eligible with your LMN, since they include:

• InBody composition scans — body composition analysis connected to health metrics
• Nutritional planning — dietary guidance related to your medical condition
• Structured fitness programming — an intensified version of your ongoing treatment

If your LMN covers structured exercise for a metabolic or cardiovascular condition, the F45 Challenge is a natural extension of that treatment plan.

F45 vs. Other Group Fitness: HSA Comparison

F45, Orangetheory, Barry's Bootcamp, and CrossFit are all HSA eligible with an LMN. The eligibility process is identical — the IRS doesn't prefer one brand over another. Choose based on which workout you'll actually stick with. The best HSA-eligible gym membership is the one you use consistently, because that's what your LMN is designed to support.

Using FSA for F45 Training

FSA funds work identically to HSA for F45 — you need an LMN, and then you can submit for reimbursement. F45's higher price point makes it an excellent FSA spend-down strategy toward the end of your plan year. If you've got $2,000+ sitting in your FSA in October, your F45 membership can absorb a big chunk of that before the use-it-or-lose-it deadline.
