I was looking at a pic from a few years ago of when I was at my smallest. I was tracking my food at that time and I was also running/walking 3 miles 5-7 days a week and sometimes twice a day. I was not working full time then either.  I know running and walking will keep a person slender. I want to get back to that slenderness but I'm no sure I have the time or energy to do that much again. How does jumping compare to running/walking? Would I have to give up one for the other? I love my jumping. I just want to know the comparison.
