Time to get back my body!!

Oh my gosh.. These last few weeks have just killed me.. Since I have stopped running constantly and stopped lifting weights my body has gone to pot... It's amazing how fast it can do that.. I have definently put on some inches and pounds and i have been so depressed about it so today I decided I am going to get back into a routine and some kind of diet.. the last one I was on worked but it is so hard to stay on so i need to find some kind of happy medium.. Anyone got any tips or tricks any advice or diets they have tried that works that is doable?
I did get on the treadmill this morning.. It was a good run other then of course it was on the treadmill.. Have I mentioned I HATE running on treadmills. Between walking and running I got in 3.25 miles in 42.30 mins and then I jumped on the elliptical and did 1.3 miles in 15 min giving me a total of 4.55 Miles..
Ok now I was able to get in 1.3 miles on the elliptical in 15 mins going at a medium to slower pace yet it takes me about 15-20 mins to speed walk a mile. There is something wrong with this picture.. I can do a mile quicker on the elliptical then I can run it on the treadmill.. Doesnt seem quite right.. Anyways I was able to get some ab work in and my upper body I was hoping to get into physical therapy tonight to do my legs but didnt happen..
I only have a few more weeks before logan is in school so I just hope the weather stays good. I am so missing running in this beautiful 75 degree weather.. It's just gorgeous here.. I think I may set up a schedule with a friend of swapping kids a couple times a week so I can do my running and she can go to the gym.. hopefully it will work out.. It felt great to run today.. Hope it wont take to long to get back into my miles and my old body.....
