You want something - you work for it - you get your reward! Follow these examples, and be inspired, particularly by the younger generation (featured near the end) who are increasingly getting off their phones and into physical training!  Junior leaders... No doubt there who really want it!    

Friends give encouragement and support in the gym - and great companionship elsewhere! In the gym first...   ...or, sometimes, not such helpful support! ... ...  But seriously...   Other environments - but there'll sometimes be a bit of flexing and posing... Yeah- note that age should not be stopping you!
