What's the best forms of exercise to increase bone density?

Hello fellow patients,

I'm new to this online forum but am so glad I found all of you! Currently I'm taking Forteo in hoping to build up my bone density. My results is mixed but certainly give me great hope. My spine is my main problem, it's Tscore improved from -3.5 to 3.1 in a year while on forteo.

I know exercise is extremely important but I felt I haven't been doing enough since I was only consistent in resistence/strength training and some walking when weather and time allows.

The following list is what I gathered, some are for bone building, some are for preventing falls. Please feel free to add more to the list and comment what you thinking whats helping you.
1. Resistence/Strength training of upper body, lower body and core
2. Walking on treadmill with an incline
3. Elliptical
4. High impact exercise as tolerated
5. Balancing exercise
6. Wearing a weighted vest

In your experience, which type of exercise help you the most to increase or maintain bone density?

I read that walking, cycling, yoga and swimming doesn't help building bone density but they do generally help our overall body health, strength and stamina. Hope this information is correct.

Advices and insights from any of you are greatly appreciated!
