Weightlifting is the only one that's ever really clicked for me, and I think it's cause I feel like I'm making some sort of obvious progress. Getting strong and being able to lift more, seeing muscles grow, pushing myself and exhausting my muscles, knowing I'm getting those micro-tears that will heal back even stronger.

Plus being at a gym, around other people who are working out feels motivating. Including more attractive women around than I'm used to ever seeing in day-to-day life!
