I am using a ten pound weighted with good success! I walk three times a week for about 45 minutes. I weigh 112 pounds.

I went from osteoporosis to osteopenia after just four months of using the vest with improved bone quality. My hips were stable but still osteoporosis. I will continue with the vest and Body Pump (strength training) workout three times a week. Because of my increased bone density in my spine and stability in my hips, my doctor said I didn't need Reclast at this time.

I am also adding one legged hops to my workout. See below from Better Bones website:

Here are the details of this ground-breaking study on women ages 55 to 70:
* The clinical trial tested for changes in the bone mineral density and bone mineral content, bone bending strength, and cartilage health markers.
* Before hopping, there was a 5-minute stretching warm-up.
* Study subjects began with very few single-leg vertical hops per day and over time worked up to 50 hops per day for a total hopping time of 3-4 minutes.
* Hops were progressively increased to reach 5 sets of 10 hops.
* 15-second rests were taken between each set of hops.
* By week 6, the women were hopping in all four directions; front, back, and both sides. The rotational hopping stimulated different parts of the hip.
* After 6 months, changes in the hopping leg were compared to those in the control leg (no hopping on this leg).
