Question

I'm 6 feet tall and 300 pounds of fat…I want to buy a very sturdy, stable, but compact (preferably single stack) home gym that doesn't FEEL cheap or flimsy and can target just the basic muscle groups. No bells or whistles and something upgradable.

It would be placed in the middle of my effiency apartment.  So I don't have a lot of space but I'm willing to sacrifice what I have to get a dam good workout.   Its about the space of any suburban home living room if that gives you an idea (maybe a tad smaller).

Realistically, I'm just interested in general functionality but I thought that to get something sturdy, especially for someone my size, I would have to invest in a machine thats heavy, like for bodybuilders. Money is not much an issue, I don't mind paying top dollar for something good in quality. I'll do whatever what it takes, I'm just ready to be strong, and fit.

Answer

Sounds like you're pretty serious about finally getting in shape, that's fantastic! Finding the best home gym to reach your goals as you've outlined is pretty simple if you know what to look for in a quality piece of equipment.

Based on your criteria for a home gym (single stack, upgradable, space effiicient, and sturdy) two home gyms come to mind right away that are a good option for your needs.

 Best Home Gym Options

• Body Solid G6B Home Gym
• Hoist V5 Home Gym

Body Solid G6B Quick Review
The Body Solid G6B is a single stack gym with commercial quality features like a gas assist seat adjustment, pads with lumbar support, a 260 pound weight stack, and a Patented Bi-Angular converging press station that replicates free weights and dumbbell presses.

The options for the G6B are impressive as well. You can outfit the gym with a mounted accessory rack for attachments, a cable column and leg press station.
