I was diagnosed as osteoporosis six years ago. Osteoporosis is where bones become thin and lose density. So I started weight training called Body Pump.
Body Pump is a revolutionary workout that strengthens every muscle in your body using barbells and adjustable weights.
I go to a gym twice a week. I use 10 kg weights each time. That's only 45 minutes' program. With a loud music, a young instructor will give you demonstrations on which part you have to focus.
Believe it or not, it worked on me! My bone density rate increased.
