How to Set Up a Home Gym
A step-by-step home gym setup guide: measure your space, lay the floor, buy equipment in the right order, and avoid the mistakes owners on r/homegym regret.
Set up a home gym in this order: measure your space, lay rubber flooring, buy the equipment you’ll use every session (dumbbells and a bench, or a rack, bar, plates and bench), then add cables, cardio and accessories over time.
Most home gym regrets come from buying in the wrong order: a cardio machine that becomes a clothes rack, or a rack that doesn’t fit under the ceiling. This guide is the order we’d follow, based on what owners on r/homegym and r/GarageGym say they’d do again.
1. Measure the space and the ceiling
Measure floor space, ceiling height and door widths before you buy anything. A dumbbell setup needs about 6 × 4 ft; a rack with a barbell needs about 8 × 8 ft, because the bar is about 7 ft long and you load plates from both ends. Racks are 80–93″ tall, and you need several inches above for pull-ups. Check where outlets are if you’ll add a treadmill or sauna. See small home gym if you’re tight on space.
2. Lay the floor first
Every experienced owner says it: do the floor before the equipment. Rubber horse stall mats from a farm store, such as Tractor Supply’s 4 × 6 ft mats, cost about $2–$2.60 per square foot and handle dropped weights. Compare all options in our best gym flooring.
3. Buy your core strength equipment
Choose one path:
- Dumbbell gym (about $1,000): PowerBlock Elite USA or REP QuickDraw adjustable dumbbells plus an REP AB-3000 bench. Best for small rooms and most beginners.
- Barbell gym (about $2,000): a power rack such as the REP PR-4000 or Titan T-3, a barbell, bumper plates and a bench. Best if you want to squat, bench and deadlift heavy.
- All-in-one (about $3,100): a Force USA G3 rack, Smith machine and cable station, plus plates and a bench.
On r/crossfit, one owner’s $1,000 priority list was simple: a good barbell and plates first, stall mats second, a rack third.
4. Add storage
Plates, dumbbells and bands on the floor are trip hazards. Rack-mounted plate horns, a dumbbell stand and wall hooks keep the space usable.
5. Add cables or cardio, not both at once
Once you’re training consistently, add what you’re missing: a functional trainer or lat pulldown for back and accessory work, or a rower, treadmill or air bike for cardio.
6. Accessories and comfort
A pull-up bar, bands, a mirror, a fan, good lighting and a speaker make you want to train. In a garage, add heating, cooling and rust prevention; see our garage gym guide.
Mistakes owners say to avoid
- Buying too much too soon. An r/homegym owner’s advice to a new builder: resist buying more equipment before you’ve used what you have.
- Skipping the floor. Foam tiles don’t last under weights.
- Forgetting the ceiling. Measure before buying a rack.
- Leaving equipment in damp, uninsulated spaces. Owners with outdoor and shed gyms report rust.

Frequently asked questions
What should I buy first for a home gym?
Start with the equipment you'll use every session: adjustable dumbbells and an adjustable bench for most people, or a power rack, barbell, plates and bench if you want to squat, bench and deadlift. Put flooring down before any of it. Add cables, cardio and accessories later, once you know what you actually use.
How much space do I need for a home gym?
A dumbbell-and-bench setup fits in about 6 × 4 ft. A power rack with a barbell needs about 8 × 8 ft, because the bar is about 7 ft long and you load both ends. Measure ceiling height too: most racks are 80–93 inches tall, and you need room above for pull-ups.
What flooring do I need for a home gym?
For free weights, ¾-inch rubber horse stall mats are the standard: cheap, dense and tough enough for dropped deadlifts. Foam puzzle mats are fine for bodyweight work and yoga but wear out under weights. Owners on r/homegym say do the floor first.
How do I set up a home gym on a budget?
Buy the essentials first, buy used where it's safe (plates, kettlebells, racks), and skip machines until you need them. Owners on r/GYM note you can sometimes buy a whole used gym on Facebook Marketplace for about $1,000. See our home gym on a budget guide for full shopping lists.
