I have been training most my adult life and motivation has never been a issue until the last year. My motivation was normally my sport and training for an event. I guess that kept me motivated. Plus my body is feeling it the last 3 or 4 years and I guess at my age I need to start understanding I am getting older... Over the years have changed the type of training from strength training to at the end more intense cardio and boxing. I also Ignore the alcohol advice.
