I have a yearly cycle of weight gain and loss. I usually lose about 10 lbs in the summer and gain 15 in the winter... I noticed this year, as I started my yearly summer running/ weight loss, that I have lower back pain during and after running that I’ve never had before. I enjoy running and usually get in 3-5 runs a week during the summer months. This year is different, I wake up in pain dreading the feeling of my feet hitting the floor and the inevitable pain that will go with it. I decided this week to try something different to get in better shape this summer. I put on a ruck sack and headed out for about an hour and a half. To my surprise I felt like I had a good workout even though the perceived effect was lower. Best of all is my back didn’t hurt afterwards. Three days in a row now, I’ve done at least 6 Miles a day with the ruck. I’m feeling much better overall than I was while running. I think this is going to be my new go to cardio.
