My friend recommended strength training to me because I was always in a ton of pain because my muscles (lack thereof actually) did a bad job of holding up my loose (?) bones (I have RA), so I started strength training and it has made sooo much of a difference in terms of my energy and joint pain and general health. It’s also very mentally empowering to not feel extremely feeble and frail at all times of every day, and I think being in a more science-based strength training situation helps me prioritize feeling strong and not worrying so much about an aesthetic result.
