I started walking the day of surgery and never looked back. I walk every day. Now, I'm up to walking 1-40 minute session and 1-30 minute session per day--that's over 2 miles per day which sounds wussy, but is HUGE for me.
At 6 weeks I was released to do strength training and I began in PT again to help me build core strength and endurance in preparation to working with someone to help me with a strength training (weights) plan. I have no limitations.
