Each day you work your exercises. Following the regimen is based on what has worked for others in the past.
Some days you feel like you are getting somewhere. Swelling goes down. You can do two laps instead of one around the living room. You still feel refreshed when you finish 10 prescribed exercises.
Somedays feel like a plateau. I know I’m doing what is needed. And I fully expect in few days I’ll see results. But yesterday, and possibly today I’ll just be doing what needs to be done!
