The docs seem fairly certain the direction it flows is weakness leads to sickness. Apparently something to do with muscle tissue vs insulin response. Lower muscle tissue leads to lower BMR which leads to obesity related issues and insulin resistance issues. Its almost too trivial to point out the orthopedic issues like weak back muscles leading to back problems. Also the accidental injury issue is trivial obvious; when I was younger working on a home improvement project I dropped a solid wood (not hollow core) door and then caught it, wrenching my back, obviously if my arms were stronger I wouldn't have dropped the door to begin with, and if my back had been stronger (I had been taking a break from lifting) then my back wouldn't have been as messed up. https://www.ncbi.nlm.nih.gov/pubmed/15107011?report=abstract https://www.ncbi.nlm.nih.gov/pubmed/15107011?report=abstract
