One thing I’ve learned from training adults 50 years old and up is that each of their stories, and bodies, is different. A cookie cutter exercise prescription is less likely to work and may lead to injury. This can result in abandoning very good intentions of adopting a more active lifestyle.
Genetics, old injuries, body structure and weight, exercise history and osteoarthritis all play a role in how the body will perform as it ages. The major joints come into play and will likely make themselves heard loud and clear. The shoulders, knees, hips, and spine are the joints most likely to affect mobility.
