i use crash pads for my oly lifts, tho i'm lifting in my outdoor homegym, but i imagine it would help for condo. Get something like this. But beware, it's huge, since you're staying in condo i'm gonna assume you're tied for space unless it's at least 2000+ sq.ft ones.

Also, without saying, bumper plates of course. And most importantly, you do not have to "crash" or "release" your full weight during the descent, hell even when i'm lifting in gym i try to control the weight down, because i'm not ego lifting or constantly trying out my 1rm. Instead i'm purely lifting for health so i choose a weight that i can handle for 8x5 yet it completely leaves me shaking by the last 2 set.

I live in a condo unit.

As a bodybuilder, I only do RDLs.
RDLs builds my hamstring while Squats hit my quads. Perfect balance.
Get a nice hamstring stretch at bottom of each RDL rep.
My RDL max is 160KG, i do sets of 6~8 reps.
RDLs also grows my traps alot due to constant tension. Lower back also gets hit hard.

RDL = Solid Hams/Traps/Low Back builder + Condo/Floor/Noise friendly

Don't see a point to do a suboptimal hypertrophy exr like deads.
Won't build your hams as good as RDLs.

have u found any solution ?

maybe can try 5by5 so less heavy and less noise ?
