So, we’re looking at Osteoporosis and which type of exercise is best for it. This study looked at how weight bearing exercise (that is, exercise where you bear your own weight, like running, as opposed to swimming, where your weight is supported by the water) compares with resistance exercise (that is, weights). Hope I haven’t used the word weight too much yet…
Now we all know that weight bearing exercise is better than non weight bearing for increasing bone mineral density. There had been some studies in recent years where it …

So the theory goes something like this: Osteoporosis develops as your bone mineral density decreases, which happens with age (after menopause it can really accelerate). Your peak levels are in your mid 30’s. The higher you can get your bone mineral density at that point, the longer you will be able to stave off osteoporosis.
Two really important factors for increasing your bone mineral density (BMD) are diet/nutrition, and exercise (traditonally weight bearing exercise such as walking has been championed, but also resistance exercise, that is, weights, have been shown to …
