I have the feeling I’ve always had a weak back.
Some 4 months ago I started working out regularly. Now I can almost touch the floor with my hands without bending my knees.
While doing this exercise I heard a small crack on my back, nothing serious.
Since then I can lift weights easier than before but my back still hurts a bit. My back doesn’t hurt as much after coming home from work, which was normal before.
What else could I do to have a stronger back?
Yoga in general and deadlifts are what I do. Back extension in both directions laying on your belly on a bench is good for strengthening it safely, start with small range of motion and extend it as you can.
Remember a few things - we spend more time bent forward than back, so make sure to strengthen the back in the arched direction as well. The whole body is connected so develop it in a balanced way. And move in every direction (intentionally). That last one is what yoga is so good for.
