Have been on myfitness pal for the whole time, I love it. My knees aren't bad, they just begin to bother me, and I don't know if I should push on, or stop. The last Dr I talked to about them said I would need an MRI to tell if there was a problem...
That's why I came up with the drop weight and see theory. Just gonna take the running slow and see. No time or extra cash for the gym, looking at body weight workouts I can do at home, and I have a set of 25# barbells... lol.
push-ups, pull-ups, bw squats, leg raises, if you can be physically active for an hour a day or 3 mins everyday you should be good it may become monotonous though. For your knee just take it easy until you feel you should test yourself.
