This is, more-or-less, a repost of my response to a similar question posted here in the past.
I have a small gym on the second level of my home, and have learned a few things over the years.
I initially had a Soloflex and then switched up to a Bowflex believing the Soloflex was too limiting. After a year of the Bowflex pretty much gathering dust, I decided to add a treadmill and purchased one of Sears’ ProForm treadmill units. Although it was more expensive than I would have preferred, it has many features of a commercial treadmill, and that was important to me because I didn’t want to give myself an excuse not to use it, so I didn’t concern myself too much about the cost. After all, the most expensive treadmill in the world is the one that doesn’t get used.
I also have a LifeCore elliptical machine, which was very reasonably priced. A Caveat on LifeCore is that their products, as far as I’m aware, are available for online purchase only. Why does this matter? Well, when I purchased my treadmill, Sears delivered it, brought it up to my gym, assembled it, and placed it where I wanted it; good thing too, because it’s over 250 pounds. The elliptical machine, on the other hand, was delivered by UPS in a box, disassembled, and left in front of my garage door. I had to get the thing in the house, up to my gym, and assemble it myself…no fun at all.
Another thing to bear in mind if you want to be serious about working out at home, is to make the environment as appealing and stress-free as possible. If your workout feels like a chore or the environment is uncomfortable, you will quickly find excuses not to do it. To that end, I made a few investments that help to improve the experience.
I purchased interlocking rubber matting for the floor from Modell’s Sporting Goods. They come in 12x12 and 24x24 inch panels that are a half inch thick. The matting not only protects the floors from scuffs and scrapes from the equipment, they absorb impact from floor exercises and help to ease the stress that comes from running on the treadmill. Not only will your knees and ankles thank you for it, it makes the room look more like a gym. See? Form and function.
I also have a TV/DVD combo unit wall-mounted within easy eye shot of all the equipment and exercise areas. I subsequently added a laptop and connected it to the TV to give me broadband entertainment options as I work out.
A modular, expandable, multi-shelf aluminum rack with casters holds all my smaller equipment and related paraphernalia, e.g., wrist and leg weights, rubber dumbells, free-weight plates, resistance straps, etc…
One of the last things I did was have one wall covered end to end, floor to ceiling, with a mirror. It’s actually two 6x9 ft mirrors placed side by side, but the installers did such a good job that you really have to look for the seam to see it. Not only do mirrors help you gauge your progress visually, they make the room look twice as large.
I also painted the walls a bright, cheery color, and mounted motivational posters.
It all works for me. I exercise between 40 minutes and an hour every day when I’m home. It’s so much a part of my daily routine now that I don’t really think about it anymore. Although I gravitate to the treadmill most days, I do use the elliptical, and even the Bowflex from time to time. The bottom line is I’m in there working out, which is much more than I can say about my old WoW membership I let lapse.
