@pamperme At the center where I am almost finished with my 20 sessions of external beam treatment, they aren't set up to facilitate exercise immediately prior to getting the treatment.

What I've been doing is to walk up stairs 5 floors and back down, then back up and down, for 5 - 10 minutes depending how organized I've been that day, prior to checking in as available for treatment. The check in procedure, changing out of street clothes, drinking the prescribed amount of water, and waiting in a room registered as available for treatment typically results in about a 30 minute delay from exercise to treatment.

I think Newton has experimented with exercising patients for longer periods then immediately, with no delay, putting them on the table for radiation. He thinks that is the best way to do it.

I don't think anyone has yet done a trial of similarly staged patients who were randomly assigned, one half who were exercised immediately prior to radiation, or to another half who did not exercise to see what happens. His theory makes a lot of sense though.
