Thanks for the articles. Knowledge is key to handling arthritis. As to exercises that have helped most, there are two areas. The first is the flexibility and/or range of motion. I target neck, shoulders, spine, hands, and hips. These I do every day. I spend about 20 minutes on these. The second is the weight training, two days a week. Dan Abrams recommended I go from a 12-15 rep target to 6-8 rep target on each of 3 sets. They also suggested I go from an hour of cardio (biking and fast walk) to 30 minutes. With weights, I target upper body, core, and legs. Upper body includes presses, curls, extensions, rows, etc. Core includes side planks, front planks, crunches. I use a foam roller for some of the spine exercises. Legs are several variations of squats. I highly recommend you go to a personal trainer such as those at Dan Abrams. The help they gave with targeting various joints was what helped the most. Form is crucial in protecting the joint, and maximizing the muscle development. I spend about 1 hour on weight training, two days a week.
