Interesting turn of events!
I live with chronic pain and sometimes (I admit) I use that as an excuse to quit early or not workout at all. My 9 year old son helps to keep me honest; he pushes me, encourages me and will workout with me (I bought him his own little set of dumbbells). We also watch 'American Ninja Warrior' together, which is a blast! (Monday 8/7C on NBC). Having children as buddies and/or motivators is amazing. Kudos to you and your experience
