What are some tips for training a client who has MS?

Depends on how aggressive the MS is with that client. I recently had a client with progressive MS. She was an ex professional dancer/choreographer for Disney and an ex-professional cheerleader for the Rams, so she did not want to be treated like she was disabled. She knew she had limitations on what she wanted to do and what her body/brain/nervous system was going to decide on what it wanted to do, but it was all about the Intention of trying. I modified all of her exercises so she could activate those muscles that were always in a fixed position due to being in a wheel chair most of the day. For some individuals, it may be challenging to exercise someone with MS because there are sometimes when you need to muscle their bodies in the position you want to get them in. Most of the time you can use their momentum to adjust a position, etc. When it came time to pass my client on to the next trainer that I trusted, I had to make sure they not only had the knowledge, but they also needed to have the strength.
