Advice on back pain based on personal evidence (single data point).
- Did squats and deadlifts for the first time at age 33. Did them for 1 year. At age 36, again did them for 3 months. (I'll get back into it again once I'm done with my current hectic schedule. Planning on doing at least 3-6 months every year).
- Here's how I sleep: No mattress. I create layers out of (bottom to top):
- Solid floor,
- Carpet or rug,
- Gym mat,
- Thick korean type blanket (mink blanket?), folded twice or thrice,
- a comforter folded twice,
- Regular bed sheet
This makes a layer soft enough so I can sleep, but still stiff enough that I can feel the floor.
In addition, I take two large towels, each twisted into a thick rope, then rolled into something resembling a cinnamon roll. One supports my back, one my tummy/abs area. When I lie upright, they're on my left and right. When I lie on the side, one is next to my back and one in the front next to my abs. Every time I twist or turn while sleeping, I've developed a habit of pulling both in to keep them packed tight next to my body.
I'm 39 now. Have been sitting in front of a computer all day for the last 20 years. Never experienced back pain.
