I have a home-gym setup back when I'm not at Uni consisting of-
-Great quality power-rack. This is by far the best investment you can make imo- 'center of the gym'
-200kgish (440lbs) assorted metal plates. Wish they were bumpers & 'taller' for lifting off the ground.
-Adjustable DBs up to about 20kg or 30kg with all little plates on 1 DB.
-I chin in the power-rack, make-shift dip using parallel bars across pins in power-rack.
-Shit semi-adjustable bench w/shit leg extension/curl. Couple of light bands. NON-olympic bar (10kg)
With what I have in theory I can do a lot of decent work, adjustments I want to make are:
Not even consider anything other then olympic bar/plates, preferably bumper plates. Little plates to have 2 DB's adjustable up to around 50kg. Probably most importantly a wider, non-shit flat or GOOD adjustable bench.
Dream would include- Proper lifting platform, proper dip station/rack that included, a calf raise, EZ-bar. Most stuff outside of that is unrealistic for the space I have, and beyond that I can't help but thinking a gym membership is the better option unless having a lot of space and money
