4 weeks out from surgery

well I am down only 25 pounds since surgery, I read and read all the discoussions every day and am feeling a little discouraged by my smallish weight loss ( I KNOW that without this surgery I would not have this weight loss) but still on a better note my knees have not hurt since surgery! no pain meds for them at all! I Wii Fit every day starting with yoga, then on to strength training mostly legs and arms I can not do pushups yet nor can i get on my knees for the exercises. then on to aerobics! I started with the basic step but is was too slow and my coordination was off :( but once I unlocked the advanced and freestyle step I am loving it! I now do just the freestyle and at top speed I can now do 30 min without feeling like I can't breath or my knees killing me! (tomorrow I am going to do 45 min and see what happens) then I go for a walk around the driveway to cool down! I am even doing the 1 person run (short) but still I am proud of my progress a month ago no way could I have done this:)
