Short answer: A commercial gym needs a cardio mix, not a wall of treadmills. For most facilities, plan roughly 50–60% treadmills, 20–25% low-impact machines (elliptical, bike, recumbent), 10–15% climbers/steppers, and 5–10% rowing machines. The exact split should follow your members’ age, fitness level and peak-hour demand — not a supplier’s stock list.
Cardio is where most members spend their first 20 minutes and where most wear happens. Getting the mix and the grade right protects your budget and your uptime. This guide breaks down which commercial cardio equipment you actually need, how many units, and how to avoid the classic mistakes.
1. Start With the Cardio Mix, Not One Machine Type
Every cardio machine type serves a different member. A well-planned floor gives members a reason to return and spreads wear across more units, so no single machine gets hammered to death.
| Machine | Ideal share | Serves |
|---|---|---|
| Treadmill | 50–60% | Walkers, runners, interval training |
| Elliptical / cross-trainer | 10–15% | Low-impact, joint-friendly cardio |
| Upright / spin bike | 10% | Cycling fans, class warm-ups |
| Recumbent bike | 5–10% | Older members, rehab, back support |
| Stair climber / stepper | 10% | High-intensity, glute/leg focus |
| Rowing machine | 5–10% | Full-body, strength-endurance crowd |
2. How Many Cardio Units Do You Need?
Do not guess from total membership — size to peak-hour concurrent use. As a starting point, plan one cardio station per 8–12 peak-time members. If your busiest hour sees 40 members and roughly 60% use cardio, that is about 24 stations.
- Small studio (200 members): 8–12 cardio stations.
- Mid-size club (600–1,000 members): 20–30 cardio stations.
- Large 24/7 gym (2,000+ members): 35–50+ cardio stations.
Round up for treadmills — they are always the first to fill and the first to be complained about when unavailable.
3. Commercial Grade Is Non-Negotiable
Cardio machines take the most abuse in any gym. Home-rated units are built for a few sessions a week; commercial gyms run them 10–18 hours a day. Insist on commercial-rated frames, motors and drives, and check the continuous-duty motor rating on treadmills (typically 3 HP AC or more for high-traffic sites).
- Continuous-duty motors and sealed bearings — not peak/hobby ratings.
- Replaceable belts, decks and pads with published part numbers.
- Consistent connectivity (USB/Bluetooth) across the fleet.
- Matched styling across brands for a premium look.
4. Layout and Comfort Details That Matter
- Spacing: leave 0.8–1 m between machines and clear access behind treadmills for safety.
- Power and data: plan floor boxes before delivery; retrofitting cable is expensive.
- Ventilation and cooling: cardio zones need strong airflow — members overheat fast.
- Entertainment: screens or a viewing wall keep members on machines longer.
5. What Commercial Cardio Equipment Costs
Factory-direct, budget roughly these per-unit ranges for commercial-grade cardio:
| Machine | Typical price (factory-direct) |
|---|---|
| Commercial treadmill | $1,200–$3,000 |
| Elliptical / cross-trainer | $900–$2,000 |
| Upright / spin bike | $400–$1,200 |
| Recumbent bike | $600–$1,500 |
| Stair climber | $1,500–$3,500 |
| Rowing machine | $600–$1,800 |

6. Maintenance: The Hidden Cost of Cardio
Cardio machines have the highest maintenance load in the gym. A simple routine keeps them running: weekly belt and deck checks, monthly lubrication where specified, and prompt replacement of worn pads and cables. In a busy gym, budget 2–5% of equipment value per year for parts and servicing — and always keep one spare treadmill belt on the shelf.
Frequently Asked Questions
How many treadmills does a commercial gym need?
Roughly 50–60% of your total cardio stations should be treadmills. A club with 24 cardio stations would run about 12–14 treadmills, with the rest spread across ellipticals, bikes, climbers and rowers.
Are treadmills or ellipticals more popular?
Treadmills are consistently the most used cardio machine. Ellipticals and bikes come next, with climbers and rowers filling out the mix for members who want variety or lower impact.
What is the best commercial cardio machine for a 24/7 gym?
Commercial-rated treadmills and low-impact ellipticals, chosen for reliability and easy maintenance, are the safest core for 24/7 operation. Pick models with published part numbers and simple, tool-light servicing.
Should I buy home or commercial cardio machines?
Commercial, always. Home machines are not built for continuous, varied use and will fail quickly, creating downtime and safety issues in a commercial setting.
