No problem, @becsbusddy. I also found Carol Michaels on YouTube. She specializes in safe exercises for osteoporosis. I do better with DVDs - so I purchased three of hers from Amazon. I'm happy with them. After getting back to strength training after a terrible year with an autoimmune disorder, they're the right pace for me now, challenging enough. They can be made more challenging with more repetitions and heavier weights as strength returns.
