I think her main issue is lack of space. She talked in other threads about w/o in her living room. If i remember right, she lives in an apt. What you could do...buy a barbell bar that collapses with plates. then take it apart and store under the couch, depending on the style of your couch, or under a bed. the plates can also be used holding them instead of a dumbell. i do this sometimes too. i hold a 15# for squats, side lunges, step ups, overhead tricep extensions, and doing crunches.
i have limited space and limited db's too. my only set of 2 db is 25# each. clearly i often can't go that heavy, so i use my single adjustable wt and do one arm at a time. or hold a plate with both hands. i use them for different things. like the adjustable for doing bicep curls, so this stays at the same wt. for squats and deadlifts i use the cast iron 25's.
there's also a ton you can do with resistance bands. that may also work for now. no storage issue, and don't have to worry about any kids messing with it. sometimes my kids like to roll the db's around. obviously some toes get rolled over.
or like i said before, ankle wts are very versatile.
