I am 3 yr female who used to run in high school, started a walk/jog exercise self-training program a couple months ago. I feel so much better after going out for a 5-mile walk/jog, and the hardest thing is to find the time around work schedule (shifts change all the time, from very early to late shifts, and a lot of 6-day weeks). How do I know when I reach a place where I need to 'crank it up'? I'm thinkng it's taking a bit longer because I haven't maintained a consistency (just short walks for several days, then a long walk/jog for a day or 2, then back to almost nothing 'cause of the work thing).View Thread
