My therapist wants me to try some

So I have a very bad tic of pacing back and forth. I pace pretty fast and it can be very exhausting pace back and forth many times a hour so he wants me to try this instead
This way I'll be sitting and still able to move my legs. He thinks it will be much easier on my body..

Plus is my mind can replace the need to pace with the bike, I might have this tic less in public and at work.

So we'll give it a try

Plus Star will need this for her rehab in a few weeks so what can it hurt
