@jspr422 I learned a valuable lesson on how much I can lift recently. For context, I have severe osteoporosis in my spine. My doctor said lift no more than 30lbs. So I learned, under 30lbs is an issue if you lift it with arms outstretched. It feels like a “no duh” now, but I felt the object I was lifting was much lighter than what I’ve lifted recently so wasn’t really thinking. But I can tell you with confidence it’s every bit about how you are doing the lifting as it is about the weight itself. Of course you should engage the core (lower abs, straight back, bend the knees, etc.) but lift/carry the weight close to the body if you have osteoporosis of the spine. Always good to have your physical therapists input. And hopefully you are also doing your physical therapy exercises 3x/week to maintain balance and strength.
