I do believe that there are some concerns that we, as trainers, should be mindful of when training menopausal and post-menopausal clients. If your client has not been doing any kind of strength training before menopause, it is a very good idea to ask if they have had a bone scan done. Women with osteoporosis and extreme osteopenia may be contraindicated from doing flexion exercises (especially if the bone loss is in the neck or lower back).
I have found that many of my clients who have returned to strength training after a few years have a harder time accumulating muscle mass than they did pre-menopause. They should be counseled to be patient and to work their bodies appropriately.
That being said, clients around my age (56) are, on average, more dedicated and more disciplined in their training than many of their younger counterparts.
Wishing you Strength~Joy~Wisdom
