Securing a power rack on post tensioned concrete
Hello everyone. First time caller, long time listener. I've finally gotten around to convincing the missus that not only do I need a power rack in the garage, I need one as soon as possible, because the gym is about to become a zoo with all the post-holiday repenters taking up already sparse rack space.
I however have one problem. All of the concrete in my house is post-tensioned. So, naturally, I can't drill into it to sink some lag bolts or something to secure the power rack.
I am looking for ideas. Right now I am thinking that a good 500 lbs of weights or so on the rack itself should do well to give it enough inertia that I can safely re-rack or drop weight onto the safeties. I am mostly concerned about tipping backwards on a bad/failed squat and knocking the rack over. Though, I'm not convinced this can even be avoided with bolts because the bolt holes I've seen on these racks arent big enough for substantial hardware anyway.
