I belong to a dance studio where I do jazz dance weekly (2,5 hrs) and I belong to a gym where I go two times a week and do the weightlifting machines to have the power to dance

I didn't join the latter until May this year. I felt that I really really had lost power in the last year or so and felt I need to strengthen my muscles. The good thing is it helps your joints ( as the muscles help holding them), your back and it is good for osteoporosis (my mom being very osteoporotic I am afraid it might happen to me too) as it increases the growth of bone substance.

Plus I hope I will have arms like Madonna in a year
