I started lifting weights at ~23 years old after the internet pointed me to buying a copy of the book Starting Strength.
Here is a brief history of the monthly gym dues I’ve paid over the years:
At an average of $100/month x 12 * 8 years I spent ~$10,000.
Knowing the math, I calculated the cost of building a home gym, and came across the /r/Homegym subreddit that sort of serves as a pornography library for this type of thing.
There are a few considerations to reflect on before proceeding with how to build a home gym:
There is an active market for used gym equipment where you can sell off all of your equipment in the case of any of these situations.
But buying a gym membership is the ultimate insurance against these 3 risks.
It’s a great resource, they have got a great Wiki.
It wasn’t the only Q&A/FAQ I referenced in shopping for my home gym but it’s great and gave me a sense for pricing.
My first purchases were off of Craigslist, where I found a single listing:
All-in it cost $120. Next step was picking up more plates.
I found a second Craigslist listing where a local gym was liquidating their steel plates as they were replacing them all with bumper plates. I think they charged a flat $1/lb:
Total cumulative cost: $480
With this setup, I could squat, bench and deadlift up to 535lbs (something I have never done yet in any single lift).
I’ve bought/sold a few items here, none of which were gym equipment.
I would recommend checking it out, however you will likely get sidetracked browsing products unrelated to your home gym!
If you don’t want to destroy your plates or your garage floor you will need special flooring.
Based on recommendations in /r/HomeGym, I visited my local Tractor Supply Co to buy these:
I bought 4 for $180 total, stacking 2 on top of each other to cover an 8’x6’ area of my garage.
The store helpfully rolled them up for me and fit all 4 into the rear of our Prius with the back seats folded down.
When we first bought them they smelled awful of an odd plastic smell, but within a week or two the scent had gone away.
Total cumulative cost: $660
In Soquel, California, my girlfriend and I were walking around the neighborhood and saw a used sports supply company.
Their basement had a large selection of new and used barbell plates, priced reasonably at $0.60/lb so I picked up:
Total cumulative cost: $670
I made the foolish mistake of buying a pair of cheap 5lb plates off of Amazon.
I discovered after they arrived that they weighed significatnly different than advertised (or relative to each other).
I didn’t return them (which I now regret). Don’t make my mistake–do not put up with being sold garbage!
Total cumulative cost: $720
As I got interested in olympic weightlifting I went ahead and bought bumper plates directly from RogueFitness.com:
They shipped them direct to our house, but it took a while and one 20kg plate was missing from the first shipment so I had to call Rogue support to send another one (for free).
Here’s a screenshot of the two orders I placed with Rogue through their website:
Total cost of Rogue equipment: ~$1.1k
