Yup, you should do it when you can! I haven't been so excited about training for a long time. Going through this process is lighting up that fire again.Nice!
Love home gyms, I'm definitely going to do one when I get my own home. Long-term wise it's much better than a regular gym. Stuff on classifieds are your friend. Friends and colleagues of mine who've gone down this route have gotten steals off them.
I can do all the squat rack curls I want without re-percussion
Overall it will be slightly over 2" thick. If I want to bolt down my rack I could use 1 3/4" screws. I'm still unsure if I want to put the thicker plywood down first or as the second layer and I have no clue if the plywood crossing is even optimal. I just want to lay the plywood whatever is best to keep the platform as stable as possible and protect my floors. I would hate to creat this platform for it to start getting wobbly. I know nothing about this kind of stuff so any suggestions would be appreciated.
Look second hand. You can get it for a quarter of a price.
I got a decent home gym from over the years. Squat rack, bench, power station plenty of weights.
Just keep an eye out. I remember i was at a thrift store and they had weights there Olympic size. I grabbdd a bunch of 45 lbs plates and offeres up $20... They accepted.
Second hand is the way to go if you have a budget.
