That's pretty amazing! Good for you! My bone density is -3.5 and after a series of 13 spinal compression fractures, I have a fear of fracture risk with weights. I do use 5 pound weights while walking on a treadmill 30 minutes in the evening, in addition to 30 minutes trail walking earlier in the day. Grand children keep me busy as well. It is so important to stay active for sure. I am 67 so figure I need to keep ahead of this and really appreciate all the info shared on this site. Thank you!
