If you’ve been told to “take it easy” because you have arthritis, I’m here to tell you that’s bullsh*t advice. Strength training isn’t just safe when you have arthritis — it’s one of the best things you can do to fight it. And I don’t just say that as a trainer — I say that as someone living with arthritis in both shoulders, my left knee, and as someone who had my right hip replaced due to osteoarthritis.
