When I was first diagnosed, I initially found this post very helpful because I had such minimal knowledge of heads/HSD, and desperately needed guideline recommendations for exercise. However, I now realize this exercise advise is completely inaccurate and potentially harmful. 150 hours per week of exercise is a lot for the average EDS patient and can only be achieved after YEARS of slow and stable progress. Furthermore, I have multiple highly qualified medical professionals (including a rheumatologist and orthopedic surgeon) warn me to never use an elliptical because of the proclivity towards hip subluxation for hypermobile people. This caution can be applied towards many exercises but apparently ellipticals should always be avoided.
