Exercise
can increase bone density
denser = stronger
puts stress through the bones
stronger = less likely to break or fracture
strengthens ligaments and tendons
adapt with exercise
less likely to injure yourself
weight-bearing exercise can help prevent osteoporosis
get older = body gets slower at repairing and strengthening bones
osteoporosis = disease where bone density is SO LOW your bones are fragile and fracture easily
where you support your whole body weight e.g. running
larger force on bones = the better your body is at strengthening bone
