@jeepgrl , I have joined Orange Theory Fitness Classes. They have 50 minute strength classes and 2G and 3G classes. 2G for 2 groups, Rower to warmup, then on the floor to get stronger with free weights with a coat and TV Screen showing the workouts and then the treadmill. Three oups are the 3G classes that have 1/3rd rower, 1/3rd weights on the floor and 1/3rd treadmill. The coaches are great, making sure I do the exercises correctly and showed me how to lower my bench since I am less than 5 feet tall. I am getting stronger. Hoping this helps my bones as I am eating a lot more protein and making sure I get enough healthy fats for the fat soluble vitamins. I don't want to have my S-shaped scoliosis spine curve more and I don't want anymore bone loss. I hope I can get out of osteoporosis. I will keep you all updated.
