I'd include pictures of what I did but honestly, I don't see how. I see how to link pictures from the internet but not direct photos from my device. But I went a little nuts on this and am loving it. Power rack with lat/low row attachments and pullup bar. Hex bar for deadlifts and silencer pads. 5 to 100 lbs dumbbell set and rack. Adjustable incline and a separate flat bench. Preacher curl. Leg extension/curl machine. 20"x24"x30" Plyobox for box jumps. Hyper Back Extension. 8-45lbs plates, 2-25s, 2-10s, 2-5s. A bunch of attachments for the pulley system. Straight bar. Curl bar. Concept2 Rower. TRX and SPIN cycle for the wife. I went about 10k into this project which gives additional motivation to use it daily.
Thought about adding a slant board (may still, they are cheap), leg press (space eater though and can do the work with other means), fly and rear delt machine (can do the work with dumbbells), and calf raise machine (currently doing one leg calf raises with dumbbells in hand holding the hand rail on the steps to the gym). Not sure if I need to do any of this but at some point I might go there. May also want to get a weight belt with chain to attach weights, currently I just cross the legs at the ankle to hold a dumbbell though this can be uncomfortable with heavier dumbbells.
