I am fairly athletic and do cardio and strength exercises since I was in a school (60+ now). I do it without gym though For cardio I bike, hike, swim in open water etc. For strength I do some bodyweight stuff that does not take up much time at all. I also have rowing machine and treadmill that I use in winter time. Thought of visiting gym had never even occurred to me.
