I walked, lunged, and did squats today

I walked over 2.7 miles per hour today for 11 minutes.  I was supposed to walk for 10-30 minutes which I did.  I walked for nearly 1000 steps.  I feel great about this accomplishments.  My legs feel like jelly after the strength training, lunges, and also the squats.  I feel like I am in better shape.  Exercise is something that I plan to continue to do and I hope I never quit.  I want to lose weight and stay in shape after I lose.  I will do a few stretches, which is I admit I should have done beforehand, but I won't skip the stretching at all.  I actually plan to walk tomorrow despite the fact that I rest on Sundays.
