Opening a commercial gym is one of the most equipment-intensive small-business builds you can take on. The buyer who plans it correctly walks away with a profitable facility for a decade. The buyer who doesn't burns through their startup budget before the doors open and underbudgets the things that actually drive member retention.
This is the practical checklist — what to spec, in what order, with realistic budget ranges. Built from real builds we've equipped as an authorized dealer for TKO, York Barbell, Defiant Strength, ANCORE, SportsPlay, and Medical Breakthrough. Not theory.
The four-phase build sequence
Most failed commercial gym openings don't fail on equipment quality. They fail on sequencing — buying the wrong things in the wrong order and running out of cash before opening day. The disciplined sequence:
- Lease + buildout — flooring, lighting, HVAC, electrical, plumbing
- Anchor equipment — racks, free weights, primary cardio
- Selectorized + functional — machines, cables, accessory equipment
- Member-facing finishes — mirrors, signage, sound, locker rooms, member tech
Don't skip phases. Don't reorder them. We've watched gyms install $80,000 of equipment on subpar flooring and watch the resale value drop 40% in two years.
Phase 1: Lease + buildout (don't underestimate)
The buildout costs that surprise first-time gym owners:
- Commercial rubber flooring — $5–$10 per sq ft for proper 3/4" interlocking tiles. A 4,000 sq ft facility = $20,000–$40,000 in flooring alone. Don't cheap out — it determines noise, equipment longevity, and member injury rates.
- HVAC capacity — commercial gyms run 30–40% above standard office HVAC tonnage. Underspeced HVAC = members complain in summer, equipment corrodes faster.
- Electrical — every cardio piece is a 120V 20A or 240V 30A dedicated circuit. Spec your power BEFORE you finalize equipment placement.
- Mirror walls — $25–$40 per sq ft installed. A free-weight section needs at least 200 sq ft of mirror.
- Sound system — $4,000–$10,000 for a properly zoned facility. Bad audio kills atmosphere; good audio is a retention multiplier.
Realistic Phase 1 budget for a 4,000–5,000 sq ft facility: $80,000–$140,000.
Phase 2: Anchor equipment
Equipment that defines what the gym is. Every member uses these. Skip a piece and you've underdelivered on a category.
Power racks
Plan for one rack per 800–1,200 active members. A commercial gym aiming at 1,500 members at peak needs 3–4 racks minimum. Spec: 7-gauge 3×3" minimum, full safeties, Westside hole spacing. TKO 920PR or 921HR for the modern commercial workhorse (matches the rest of the TKO ecosystem if you're spec'ing TKO machines), or York Barbell STS Commercial Power Rack 53006 for the traditional commercial pick that's been in university and military gyms for decades.
Per-rack budget: $2,250–$4,800 including bar and J-cup safeties (TKO 920PR with integrated storage runs the higher end). Multi-station setups like the York STS Triple Combo ($6,649) or TKO 920PR Dual ($7,334–$7,697) are more budget-efficient per lifting station for high-volume floors.
Commercial-only Defiant racks: Defiant Strength's heavy-commercial rack lineup is available to commercial buyers by request (not listed online for retail sale). If you're outfitting a high-school, collegiate, or heavy-use commercial facility and want the Defiant rack ecosystem to match Defiant's iso-lateral and multi-stack lineup, get in touch and we'll send the spec sheet and quote.
Olympic platforms
If your member base includes any Olympic lifting, you need at least one dedicated lifting platform with horse-stall mat surround. Budget $1,200–$2,500 per platform.
Free weights
The York Barbell line is the standard for commercial free weights. Plan for:
- 4–6 Olympic bars (standard 20kg + at least 2 women's 15kg + 1 specialty: power bar, deadlift bar, or trap bar)
- Olympic plate set: 2,000–3,500 lb total weight depending on member volume
- Hex dumbbell set: 5–125 lb pairs minimum, with a dumbbell rack tree
- Kettlebells: 8–48 kg, 1–2 of each weight
Free-weight section total: $18,000–$32,000. Browse free weights, dumbbells, and benches.
Primary cardio
For a 1,500-member commercial gym, the cardio bank baseline:
- 4–6 commercial-grade treadmills
- 3–4 stationary bikes (mix of upright and recumbent)
- 2–3 ellipticals
- 1–2 rowing machines (Concept2 is the standard)
- 1 stair climber (StairMaster style)
Cardio bank total: $40,000–$80,000. Browse cardio collection.
Phase 2 total: $80,000–$140,000.
Phase 3: Selectorized + functional
Member retention equipment. A gym with great racks but no machines bleeds beginners. A gym with machines but no functional area bleeds intermediate members. Cover both.
Selectorized machine line
The standard commercial gym machine set:
- Iso-lateral chest press
- Lat pulldown / mid-row dual function
- Shoulder press
- Bicep curl + tricep extension dual
- Leg press (45-degree)
- Leg extension
- Leg curl (seated or lying)
- Hip abductor / adductor
- Cable crossover (1–2 stations)
- Smith machine (1)
TKO's 7-series selectorized line is our most-recommended for commercial gym builds — biomechanics, weight stack feel, and warranty support are all class-leading. For high-school, collegiate, and heavy-use commercial floors, Defiant (TKO's premium heavy-commercial line) is the upgrade — the DS1000-series iso-lateral plate-loaded machines and MS-series multi-stack systems (MS2 cable crossover at $7,530, MS4 4-stack at $11,790, MS5 5-stack at $16,160, MS8 8-stack at $24,790) are built specifically for athletic-performance and heavy-traffic environments.
Selectorized line budget: $35,000–$70,000.
Functional training zone
- 2–3 cable machines or functional trainers
- Battle rope station
- Plyometric boxes (multiple heights)
- TRX-style suspension training stations (4–6 anchor points)
- Wall-mounted ANCORE units (if you serve athletic clients) — ANCORE collection
Functional zone budget: $12,000–$28,000.
Phase 3 total: $50,000–$100,000.
Phase 4: Member-facing finishes
The polish that separates a profitable gym from a transactional one:
- Locker rooms — $12,000–$30,000 for fixtures, lockers, showers, finishes
- Member technology — POS, access control, scheduling — $3,000–$8,000 setup, plus monthly SaaS
- Retail space — branded apparel, supplements, water — $3,000–$6,000 initial inventory
- Recovery zone — at least one massage chair (Medical Breakthrough), foam rollers, percussion devices, stretching mat area — $5,000–$12,000
- Signage + branding — exterior sign, interior wayfinding, member onboarding posters — $4,000–$10,000
Phase 4 total: $27,000–$66,000.
Realistic total budget
For a 4,000–5,000 sq ft commercial gym serving 1,000–1,500 members:
- Phase 1 (buildout): $80,000–$140,000
- Phase 2 (anchor equipment): $80,000–$140,000
- Phase 3 (selectorized + functional): $50,000–$100,000
- Phase 4 (finishes): $27,000–$66,000
- Total: $237,000–$446,000
This is before lease deposit, working capital reserves, marketing, payroll for the first 6 months, and equipment installation labor. Plan for the equipment side to be 50–60% of total opening costs, not 100%.
Common mistakes that cost first-time owners hundreds of thousands
- Buying gray-market equipment to "save money." A commercial gym puts each piece through 50–100x the cycles of a home gym. Warranty failures cost more than the savings. We wrote about this in detail — but for commercial it's not optional, it's existential.
- Skipping the platform / dedicated lifting area. Lifting members are the highest-LTV demographic in any gym. Lose them by giving them no platforms and you're competing on price for cardio members instead.
- Overspecing cardio. 25 cardio pieces in a 4,000 sq ft gym means cardio takes up 30% of the floor. The equipment isn't that profitable per sq ft. Lean cardio, lean retention.
- Underbudgeting installation. Commercial cable stations and selectorized machines typically need professional installation. Plan $3,000–$8,000 for installation labor on top of equipment cost.
- Skipping the recovery zone. A massage chair, mobility area, and proper stretching space costs <$15K and dramatically reduces post-training member friction.
Financing the build
For commercial purchases, financing through Afterpay/Shop Pay/Affirm typically caps short of full commercial budgets. We're partnered (in onboarding) with a dedicated commercial fitness lender for orders above $30,000 — coverage on equipment, fixtures, and installation. Contact us for a referral and a build sheet tailored to your facility.
Smaller orders, residential-spec buyers, or gym buildouts under $30K can use the standard checkout financing. Full financing FAQ.
What to do next
If you're at the build-planning stage, send us:
- Square footage and layout (floor plan PDF if available)
- Target member count at year 2
- Membership profile (lifting-heavy, cardio-heavy, mixed, group-class-heavy, etc.)
- Total equipment budget
We'll send back a complete equipment list with brand-specific recommendations, pricing at MAP across all manufacturers, install timeline, and white-glove delivery options. Submit a commercial inquiry here — we typically reply within a business day with the build sheet.
Or if you're earlier in the process and just want to spec individual categories, browse the commercial equipment collection.
The gyms that succeed long-term are the ones built once, built properly, and built around equipment that ages gracefully. We'd rather help you do it right the first time.
