Hi I'm Lisa, I am really looking forward to this challenge. I feel I will benefit greatly from the push ups daily. I have a twisted pelvis and bursitis in both hips with lower back pain. Needless to say I'm in a great deal of pain every day. I had some physical therapy for a period of time and was told that I have great weakness in my hips and need to strengthen the muscles. Exercise is very tricky with so many issues at the same time. The therapist described it as "there is a bunch of little kids and they are not getting along". What I have been able to do is swim and dance (zumba) or ride my bike. I have noticed some improvement in mobility (very painful to walk) over the last 3 weeks doing zumba but really needed another way to strengthen and tone my lower back and abdominal muscles and I believe this will help. I welcome any suggestions that you might have. Thank you and I wish the very best to all members who are BRAVE enough to join us in this challenge!!
