I was sitting in my office today, reading through my Food and Nutrition Magazine, when I came across a series of articles about bone health & osteoporosis prevention. You'd think the articles would be littered with fruit & vegetable recommendations and images of milk mustaches & calcium supplements, but instead of a huge glass of milk on the page there was a picture of a kettlebell. The main takeaway of that article: Weight Bearing Exercise is Key to Building AND Maintaining Strong Bones.
One particular piece stuck out at me:
Like muscles, bones are living tissue, and they require stress to stimulate growth and maintain integrity. Just as consuming extra protein without exercising will not result in strong muscles, consuming calcium without exercising will not result in optimal bone mass.
Exercise positively effects bone health in more than one way and at all ages. Weight bearing exercise stimulates mineral uptake in children and adults, which is great because although we don't usually think about fractures and thinning bones affecting us until we are well into our sixties, these conditions are directly influenced by the choices we make decades earlier.
The article went on to recommend & categorize different kinds of exercise including high and low impact weight bearing exercises, strength building exercises, and balance/posture/functional exercises. The cool thing here is that CrossFit can fall into ALL of those categories.
All our WODS include some sort of weight bearing exercise on most days, sprinkled with strength building exercises, and functional movements left & right! So not only are we all making muscular gainz, but we're also making bone health gainz every day.
