I ride a bike early in the morning for just 15 minutes on level ground. Beyond that I go by the rule of 5. That means no more than 5 reps of any exercise at any one time. The routine includes arms, legs, neck and shoulder stretches. I like the one where I put my weight on one leg while holding on the fridge and swing my legs in all directions. The amount of weight bearing is minimal but is better than nothing and it can work holding either the top of the fridge or the handles. Tomorrow I will do weeding for 10 minutes in a seated position. I am at 4 mg of Methylprednisolone and I started in Sept 2023.
